    ______________
    Before:
    WESLEY, CHIN, and SULLIVAN, Circuit Judges.
    This is a class action lawsuit brought by shareholders of Defendant-
    Appellant Goldman Sachs Group, Inc. The shareholders allege that Goldman and
    several of its executives committed securities fraud in violation of § 10(b) of the
    Securities Exchange Act of 1934 and Rule 10b–5 promulgated thereunder by
    misrepresenting Goldman’s freedom from, or ability to combat, conflicts of
    interest in its business practices. The shareholders argue that several high-profile
    government fines and investigations revealed the truth of Goldman’s flawed
    conflicts management to the market thereby reducing its share price.
    Several years ago, the United States District Court for the Southern District
    of New York (Crotty, J.) certified a shareholder class under Federal Rule of Civil
    Procedure 23(b)(3). In 2018, we vacated the class certification order, holding that
    the district court had failed to apply the “preponderance of the evidence” standard
    for determining whether Goldman had rebutted a legal presumption, known as
    the Basic presumption, that the shareholders relied on Goldman’s alleged
    misstatements in purchasing its stock at the market price. We remanded for the
    court to apply the correct standard and to consider Goldman’s evidence intended
    to rebut the Basic presumption.
    On remand, the district court certified the class once more. Goldman argues
    on legal and evidentiary grounds that this decision was an abuse of discretion. On
    the law, Goldman contends that the court misapplied the inflation-maintenance
    theory for demonstrating price impact. It also argues that we should modify the
    theory to exclude what it terms “general statements.” On the evidence, Goldman
    argues that the court erroneously rejected its rebuttal evidence in holding that it
    failed to rebut the Basic presumption.
    The district court applied the correct legal standard and we find no abuse of
    discretion in its weighing of Goldman’s rebuttal evidence. We AFFIRM. Judge
    Sullivan dissents in a separate opinion.

    ________________
    WESLEY, Circuit Judge:
    This is the second time this securities class action has arrived at our doorstep
    on a Rule 23(f) appeal. The first time we took the case, the United States District
    Court for the Southern District of New York (Crotty, J.) had certified under Rule
    23(b)(3) a shareholder class suing Goldman Sachs Group, Inc. and a handful of its
    executives (collectively, “Goldman”) for securities fraud. We vacated the class
    certification order, holding that the district court did not apply the
    “preponderance of the evidence” standard for determining whether Goldman had
    4
    rebutted a legal presumption, known as the Basic presumption, that the
    shareholders relied on Goldman’s allegedly material misstatements in choosing to
    purchase its stock at the market price. See Ark. Teachers Ret. Sys. v. Goldman Sachs
    Grp., Inc. (ATRS I), 
    879 F.3d 474
    , 484–85 (2d Cir. 2018); see also Basic Inc. v. Levinson,
    
    485 U.S. 224
    , 245–48 (1988). We also held that the court erroneously declined to
    consider some of Goldman’s evidence of “price impact”—that is, the question of
    whether the revelation that Goldman’s statements were false affected its share
    price. See ATRS 
    I, 879 F.3d at 485
    –86.
    On remand, the district court ordered additional briefing and held an
    evidentiary hearing. After concluding that Goldman failed to rebut the Basic
    presumption by a preponderance of the evidence, the court certified the class once
    more. See In re Goldman Sachs Grp., Inc. Sec. Litig., No. 10 Civ. 3461 (PAC), 
    2018 WL 3854757
    (S.D.N.Y. Aug. 14, 2018). We again granted Goldman’s petition for
    permission to appeal under Rule 23(f).
    The question before us is whether the district court abused its discretion by
    certifying the shareholder class, either on legal grounds or in its application of the
    Basic presumption. For the following reasons, we hold that it did not.

    BACKGROUND
    Factual Background
    The facts giving rise to this lawsuit are discussed at length in our prior
    opinion. See ATRS I, 
    879 F.3d 478
    –82. All that is required here is an abridged
    version.
    Between 2006 and 2010, Goldman made the following statements about its
    business practices:
    Our reputation is one of our most important assets. As we have
    expanded the scope of our business and our client base, we
    increasingly have to address potential conflicts of interest, including
    situations where our services to a particular client or our own
    proprietary investments or other interests conflict, or are perceived to
    conflict, with the interest of another client . . . .
    We have extensive procedures and controls that are designed to
    identify and address conflicts of interest . . . .
    Our clients’ interests always come first. Our experience shows that if
    we serve our clients well, our own success will follow. . . .
    We are dedicated to complying fully with the letter and spirit of the
    laws, rules and ethical principles that govern us. Our continued
    success depends upon unswerving adherence to this standard. . . .
    Most importantly, and the basic reason for our success, is our
    extraordinary focus on our clients. . . .
    Integrity and honesty are at the heart of our business.
    6
    J.A. 87–88, 93 (alterations omitted). The Plaintiffs-Appellees (“shareholders”)—
    individuals and institutions holding shares of Goldman’s common stock—allege
    that these statements were false because Goldman made them while knowing that
    it was riddled with undisclosed conflicts of interest.
    The conflicts at issue here surround several collateralized debt obligation
    (“CDO”) transactions involving subprime mortgages. Chief among them is the
    Abacus 2007 AC-1 (“Abacus”) transaction. Publicly, Goldman marketed Abacus
    as an ordinary asset-backed security, through which investors could buy shares in
    bundles of mortgages that the investors, and presumably Goldman, hoped would
    succeed. But behind the scenes, Goldman purportedly allowed the hedge fund
    Paulson & Co. to play an active role in selecting the mortgages that constituted the
    CDO. And Paulson, which bet against the success of the Abacus investment
    through short sales, chose risky mortgages that it “believed would perform poorly
    or fail.”
    Id. at 59.
    The alleged plan worked, and Paulson made roughly $1 billion
    at the expense of the CDO investors (who are not the plaintiffs here). Goldman
    ultimately admitted that it failed to disclose Paulson’s role in the portfolio
    selection, and it reached a $550 million settlement with the SEC—the largest-ever
    penalty paid by a Wall Street firm at the time. See generally Press Release, SEC,
    7
    Goldman Sachs to Pay Record $550 Million to Settle SEC Charges Related to Subprime
    Mortgage CDO (July 15, 2010), https://www.sec.gov/news/press/2010/2010-
    123.htm. Goldman allegedly engaged in similar conduct with respect to three
    other CDOs. At times, Goldman allegedly represented to its investors that it was
    aligned with them when it was in fact short selling against their positions.
    Early Litigation History
    In 2011, the named plaintiffs filed a class action complaint in the United
    States District Court for the Southern District of New York, seeking under Federal
    Rule of Civil Procedure 23(b)(3) to represent a class of all individuals and entities
    that acquired shares of Goldman’s common stock between February 5, 2007 and
    June 10, 2010. They alleged that Goldman and several of its directors violated
    § 10(b) of the Securities Exchange Act of 1934 and Rule 10b–5 promulgated
    thereunder. See 15 U.S.C. § 78j(b); 17 C.F.R. § 240.10b–5. The crux of their claim is
    that Goldman’s representations about being conflict free artificially maintained an
    inflated stock price and that the revelations of Goldman’s conflicts, such as those
    presented by the SEC in its complaint against Goldman concerning the Abacus
    deal, were “corrective disclosures” that caused the market to devalue their
    8
    Goldman shares. 1 They noted, for example, that Goldman’s share price dropped
    13% when the SEC filed a securities-fraud complaint against Goldman in
    connection with the Abacus transaction, and that it dropped even further on two
    later dates when news broke that several federal agencies were investigating
    Goldman for its role in the other conflicted transactions. In the shareholders’ view,
    these announcements revealed to the market that Goldman had created “clear
    conflicts of interest with its own clients” by “intentionally packag[ing] and
    s[elling] . . . securities that were designed to fail, while at the same time reaping
    billions for itself or its favored clients by taking massive short positions” in the
    same transactions. J.A. 49. They claim that they lost over $13 billion as a result of
    Goldman’s fraud.
    Goldman moved to dismiss the complaint under Federal Rules of Civil
    Procedure 9(b) and 12(b)(6). It argued that the alleged misstatements were not, as
    the securities law requires, “material.” 2 This was because, in Goldman’s view, the
    1A “corrective disclosure” is an announcement or series of announcements that reveals
    to the market the falsity of a prior statement. See Lentell v. Merrill Lynch & Co., 
    396 F.3d 161
    , 175 n.4 (2d Cir. 2005).
    2The six elements of securities fraud are “(1) a material misrepresentation or omission by
    the defendant; (2) scienter; (3) a connection between the misrepresentation or omission
    9
    statements were too general and vague for a reasonable shareholder to have relied
    on them in determining the value of Goldman’s stock. Thus, Goldman argued, the
    statements had no impact on its stock price, and any loss the shareholders suffered
    was due to something other than the corrective disclosures. The district court
    largely disagreed, holding that most of Goldman’s statements presented an
    actionable question of materiality. See Richman v. Goldman Sachs Grp., Inc., 868 F.
    Supp. 2d 261, 276, 280 (S.D.N.Y. 2012). The court did, however, agree with
    Goldman that some of its statements were immaterial as a matter of law; it
    dismissed the complaint to the extent it relied upon those statements. See
    id. at 274.
    The court subsequently denied Goldman’s motions for reconsideration of,
    and an interlocutory appeal from, the order denying the motion to dismiss. See In
    re Goldman Sachs Grp., Inc. Sec. Litig., No. 10 Civ. 3461 (PAC),

    552 U.S. 148
    , 157 (2008).
    10
    Class Certification and the First Appeal
    Following discovery, the shareholders moved for class certification. To
    certify a class under Rule 23 of the Federal Rules of Civil Procedure, the named
    plaintiffs must demonstrate (1) that the class is so numerous that joinder is
    impracticable, (2) that at least one question of law or fact is common to the class,
    (3) that the class representatives’ claims are typical of the classwide claims, and
    (4) that the class representatives will be able to fairly and adequately protect the
    interests of the class. See Fed. R. Civ. P. 23(a). Goldman did not contest that these
    requirements were met. Instead, it focused on an additional prerequisite for
    classes primarily seeking money damages, found in Rule 23(b)(3), that common
    questions of law or fact predominate over individual questions that pertain only
    to certain class members. See
    id. 23(b)(3). Facially,
    securities fraud appears to be a bad fit for the predominance
    requirement because the key question is whether each individual shareholder
    relied on a defendant’s misstatement in choosing to purchase its stock. But under
    Basic Inc. v. Levinson, 
    485 U.S. 224
    , courts may presume reliance on a classwide
    basis if the plaintiffs “establish certain prerequisites—namely, that [the]
    defendants’ misstatements were publicly known, their shares traded in an efficient
    11
    market, and [the] plaintiffs purchased the shares at the market price after the
    misstatements were made but before the truth was revealed.” ATRS 
    I, 879 F.3d at 481
    ; see Halliburton Co. v. Erica P. John Fund, Inc. (Halliburton II), 
    573 U.S. 258
    , 268
    (2014). 3 The idea behind Basic is that investors presume that theoretically efficient
    markets, such as the New York Stock Exchange or Nasdaq, incorporate all public
    information—including material misstatements—into a share price. 
    See 485 U.S. at 246
    ; see generally 7 William B. Rubenstein, Newberg on Class Actions
    §§ 22:16, 22:81 (5th ed.).
    Plaintiffs seeking to invoke the Basic presumption need not directly prove
    that the defendant’s statements had price impact—that is, an effect on its share
    price. See Halliburton 
    II, 573 U.S. at 278
    –79. They may instead rely on the
    requirements for invoking the Basic presumption as an “indirect proxy” for a
    showing of price impact. See
    id. at 281.
    “But an indirect proxy should not preclude
    . . . a defendant’s direct, more salient evidence showing that the alleged
    misrepresentation did not actually affect the stock’s market price and,
    consequently, that the Basic presumption does not apply.”
    Id. at 281–82;
    see also
    3Materiality is also a prerequisite for Basic, but class members need not prove it prior to
    class certification. See Halliburton 
    II, 573 U.S. at 276
    .
    12
    
    Basic, 485 U.S. at 248
    (noting that “[a]ny showing that severs the link between the
    alleged misrepresentation and . . . the price received (or paid) by the plaintiff . . .
    will be sufficient to rebut the presumption of reliance” because “the basis for
    finding that the fraud had been transmitted through market price would be
    gone”).
    Goldman attempted to rebut the Basic presumption in several ways. It
    introduced an event study designed to show that its alleged misstatements had no
    impact on its share price. 4 It also argued that the market did not react on several
    dozen occasions before the corrective-disclosure dates when media outlets
    reported on its alleged conflicts of interest; and, thus, the market was indifferent
    to this information when it appeared in the corrective disclosures.                  Under
    Goldman’s theory, its share price declined solely because of new information
    4An event study isolates the stock price movement attributable to a company (as opposed
    to market-wide or industry-wide movements) and then examines whether the price
    movement on a given date is outside the range of typical random stock price fluctuations
    observed for that stock. If the isolated stock price movement falls outside the range of
    typical random stock price fluctuations, it is statistically significant. If the stock price
    movement is indistinguishable from random price fluctuations, it cannot be attributed to
    company-specific information announced on the event date. See Mark L. Mitchell & Jeffry

    Securities and Exchange Commission, 49 Bus. Law. 545, 556–69 (1994); In re Vivendi, S.A. Sec.

    contained in the corrective disclosures: that several federal agencies were
    enforcing the securities laws against Goldman with investigations and fines for
    the same allegedly fraudulent trading practices.
    The district court rejected Goldman’s theory and certified the class. See In
    re Goldman Sachs Grp., Inc. Sec. Litig., No. 10 Civ. 3461 (PAC), 
    2015 WL 5613150
    (S.D.N.Y. Sept. 24, 2015). We vacated this decision on appeal. See ATRS 
    I, 879 F.3d at 478
    .   We began our analysis by noting Goldman’s concession that the
    shareholders successfully invoked the Basic presumption.
    Id. at 484.
    But as to the
    rebuttal stage, we found that the district court failed to apply the “preponderance
    of the evidence” standard, which our Court had clarified in an intervening
    decision.
    Id. at 485
    (citing Waggoner v. Barclays PLC, 
    875 F.3d 79
    , 101 (2d Cir. 2017)).
    We also found that, in making this determination, the court mistakenly concluded
    that certain price-impact evidence Goldman had sought to introduce was
    irrelevant under Rule 23.
    Id. at 486.
    We remanded for the court to reconsider,
    under the correct standard and with this additional evidence, whether Goldman
    could rebut the Basic presumption.
    Id. We offered
    no views on the merits of that
    question or the sufficiency of Goldman’s rebuttal evidence.
    Id. 14 Proceedings
    on Remand
    On remand, the district court accepted supplemental briefs from the parties
    and held an evidentiary hearing and oral argument. It framed the issue as whether
    Goldman could “demonstrate[], by a preponderance of the evidence, that the
    alleged misstatements had no price impact.” In re Goldman, No. 10 Civ. 3461
    (PAC), 
    2018 WL 3854757
    , at *2.
    Although Goldman bore the burden of persuasion, the district court first
    looked to the shareholders’ evidence intended to show the shortcomings of
    Goldman’s rebuttal argument. It characterized the shareholders’ claims as resting
    on an “inflation-maintenance” theory: that “the misstatements themselves did not
    inflate the stock price, [but] allegedly served to maintain an already inflated stock
    price.”
    Id. 5 The
    court credited evidence from Dr. John D. Finnerty, the
    shareholders’ expert who testified at the evidentiary hearing, “that the news of
    Goldman’s conflicts on the . . . corrective disclosure dates negatively impacted
    5 This theory is sometimes referred to as the “price-maintenance theory,” and what we
    term “inflation-maintaining statements” are sometimes called “price-maintaining
    statements.” We use the “inflation” language because it is more precise and the phrase
    “price-maintenance” also has currency in antitrust law. See also 
    Vivendi, 838 F.3d at 258
    (dubbing this doctrine the “inflation-maintenance theory”).
    15
    Goldman’s stock price.”
    Id. at *4
    . 
    It concluded that “Dr. Finnerty’s model, at the
    very least, establishes a link between the news of Goldman’s conflicts and the
    subsequent stock price declines.”
    Id. The district
    court then turned to evidence presented by two of Goldman’s
    experts to rebut the Basic presumption. The first expert, Dr. Paul Gompers, cited
    news articles published on thirty-six dates prior to the corrective disclosures
    discussing aspects of Goldman’s conflicts. Asserting that the content of the reports
    was no different than the content of the corrective disclosures, and noting that
    Goldman’s share price did not meaningfully move on the dates of the reports, Dr.
    Gompers concluded that the market was indifferent to the news of Goldman’s
    conflicts. The court found this evidence was “not persuasive.”
    Id. Although it
    agreed (as did Dr. Finnerty) that Goldman’s stock price did not move on the thirty-
    six dates, it found that “[t]he absence of price movement, . . . in and of itself, is not
    sufficient to sever the link between the first corrective disclosure and the
    subsequent stock price drop.”
    Id. This was
    because “the [Abacus] complaint was
    the first to expose hard evidence of Goldman’s client conflicts” by its inclusion of
    “direct quotes from damning emails . . . [and] internal memoranda, disclosing
    hard evidence that Goldman had indeed engaged in conflicts to its own
    16
    advantage.”
    Id. at *5.
    The court found that this hard evidence and other “material
    information” about “the nature and extent of Goldman’s client conflicts” “had not
    been described in any of the 36 more generic reports on conflicts.”
    Id.
    at *4
    . 
    6 It
    found that Dr. Gompers did not “credibly explain[] how such hard evidence did
    not contribute to the price decline following the first corrective disclosure.”
    Id. at *5.
    The district court was similarly unpersuaded by Goldman’s second expert,
    Dr. Stephen Choi. Dr. Choi presented an event study concluding that, because
    “the conflicts were reported on 36 separate occasions with no price movement, the
    . . . price drops [following the corrective disclosures] must have been due
    exclusively to the news of enforcement activities [such as the Abacus complaint].”
    Id. at *3
    (citation omitted). Dr. Choi identified three “factors” descriptive of the
    Abacus complaint: it was not accompanied by a concurrent resolution, it included
    scienter-based allegations, and it charged an individual defendant in addition to
    Goldman.
    Id. He used
    a data set of 117 enforcement actions and identified four
    6  The court noted that the articles “vary significantly” and that, while some “suggest
    possible or theoretical conflicts[,] . . . others appear to be a cri de couer from sworn enemies
    . . . [or] not damaging or revelatory, but rather commendatory . . . prais[ing] Goldman for
    managing its conflicts and still outperforming competitors.”
    Id. at *4
    n.6.
    17
    involving these same factors. The average share price decline following those four
    enforcement events was 8.07%. Because Goldman’s share price declined by 9.27%
    following the Abacus disclosure, and Dr. Choi found that the 1.2% difference was
    not statistically significant, he opined that the entire price drop was due to the
    news of the enforcement action, rather than the revelation of Goldman’s conflicts.
    The district court found that “Dr. Choi’s conclusion [was] not supported by
    his event study.”
    Id. at *5.
    To begin, it noted that Dr. Choi looked only at the
    Abacus complaint and did not examine the other corrective disclosures; the court
    found there was “no good reason to extend [his] findings” to those disclosures.
    Id. The court
    also found Dr. Choi’s three “factors” were “arbitrary characteristics,”
    emphasizing that Dr. Choi conceded “he was the first person to use [the factors]
    together” and that the factors “are not generally accepted in the field.”
    Id. The court
    then explained that the four enforcement events from Dr. Choi’s study were
    different than the Abacus event because they did not involve allegations of
    mismanagement of conflicts of interest or companies with comparable size or
    operations to Goldman. The court further found the event study did not account
    for the misconduct allegations underlying each event. It also noted that Dr. Choi’s
    study did not produce statistically significant results because it looked to the
    18
    average price decline of only four events (out of a population of 117) with a large
    variance: declines of 3.34%, 3.73%, 8.13%, and 17.09%. Finally, the court faulted
    Dr. Choi for comparing the Goldman price decline to the four events using a two-
    sample t-test, which some authorities have explained “is not appropriate for small
    samples drawn from a population that is not [statistically] normal.”

    DISCUSSION
    “[W]e review the [district court’s] grant of class certification for an abuse of
    discretion, and the legal conclusions underlying that decision de novo.” ATRS 
    I, 879 F.3d at 482

    19
    look at whether the [district court’s] application ‘falls within the range of
    permissible decisions.’”
    Id. (quoting Waggoner,
    875 F.3d at 92).
    Goldman argues for reversal on two general grounds. First, it contends that
    the district court misapplied the inflation-maintenance theory, which it asks us to
    modify. Second, based largely on the court’s evidentiary findings, Goldman argues
    that the court abused its discretion by holding that Goldman failed to rebut the
    Basic presumption by a preponderance of the evidence.
    I.    The District Court Correctly Applied the Inflation-Maintenance
    Theory, and We Reject Goldman’s Invitation to Narrow It.
    In the classic § 10(b) case, a corporation’s shareholders allege that a
    corporation, in financial statements or through its officers, made false statements
    that caused them to overvalue its stock. As noted above, the question of whether
    the statements actually affected the market price is called “price impact.” We have
    held that two types of false statements can have price impact. See In re Vivendi,
    S.A. Sec. Litig., 
    838 F.3d 223
    , 257 (2d Cir. 2016). The first category is inflation-
    introducing statements. Shareholders relying on an inflation-introduction theory
    claim that the corporation’s false statements “introduced” inflation into its share
    price because the market believed them to be true and reacted accordingly. See
    id. 20 The
    second category is inflation-maintaining statements. These statements
    have price impact not because they introduce inflation into a share price, but
    because they “maintain” it. See
    id. Imagine, for
    example, that major media outlets
    report a false rumor that a record label plans to sell a secretly recorded Beatles
    album containing a dozen unreleased songs. Although the record company
    played no role in starting or spreading this rumor, its share price increases from
    $60 to $70 because the market believes the rumor and thinks the album will be
    profitable. Not wanting to disappoint the public, the company’s CEO confirms
    the rumor even though she knows it is false. While the CEO’s misstatement does
    not move the record company’s share price—which stays at $70 because the
    market has already incorporated the album’s predicted profits—the statement is
    fraudulent because it maintains the artificial inflation. Had the CEO told the truth,
    the share price would have returned to $60. The “inflation-maintenance” theory
    allows shareholders to claim they relied on statements like these when suing for
    securities fraud.
    Our original case on the inflation-maintenance theory is Vivendi, 
    838 F.3d 223
    . There, we joined the Seventh and Eleventh Circuits in holding that “theories
    of ‘inflation maintenance’ and ‘inflation introduction’ are not separate legal
    21
    categories.”
    Id. at 259
    (quoting Glickenhaus & Co. v. Household Int’l, Inc., 
    787 F.3d 408
    , 418 (7th Cir. 2015), and citing FindWhat Inv’r Grp. v. FindWhat.com, 
    658 F.3d 1282
    , 1316 (11th Cir. 2011)). On that basis, we held, “securities-fraud defendants
    cannot avoid liability for an alleged misstatement merely because the
    misstatement is not associated with an uptick in inflation.”
    Id. Goldman raises
    two objections to the district court’s application of the
    inflation-maintenance theory: (A) in its view, the theory applies only when alleged
    misstatements prop up “fraud-induced inflation” and the court failed to make a
    finding to this effect; and (B) the court erred by finding that what Goldman
    describes as “general statements” can ever satisfy the inflation-maintenance
    theory.
    The Inflation-Maintenance Theory Does Not Require
    Proof of Fraud-Induced Inflation, and the District Court
    Applied the Correct Standard in Concluding that
    Goldman’s Share Price Was Inflated.
    It should be apparent that a statement cannot maintain price inflation unless
    the price is already inflated. See
    id. at 255
    . 
    Accordingly, a court allowing plaintiffs
    to claim inflation maintenance must make a finding of price inflation. The parties
    22
    agree on this basic principle. But Goldman would add that the price inflation must
    have been “fraud-induced.” It draws this putative rule from Vivendi. 7
    Vivendi said no such thing. In fact, the sentence from which Goldman plucks
    “fraud-induced” contradicts Goldman’s claim. “Artificial inflation is not necessarily
    fraud-induced, for a falsehood can exist in the market (and thereby cause artificial
    inflation) for reasons unrelated to fraudulent conduct.”
    Id. at 256
    (emphasis
    added). Accordingly, “the question of . . . liability for securities fraud . . . does
    [not] rest on whether the market originally arrived at a misconception about the
    model’s safety on its own, or whether the company led the market to that
    misconception in the first place.”
    Id. at 259
    . 8
    7 Appellant Br. 29 (“Although a stock’s price can be inflated for any number of reasons,
    the securities laws are concerned only with ‘fraud-induced’ inflation, 
    Vivendi, 838 F.3d at 256
    , which is ‘the difference between the stock price and what the price would have been
    if the defendants had spoken truthfully,’ 
    Glickenhaus, 787 F.3d at 418
    .”).
    8The Vivendi defendant made essentially the same argument as Goldman in opposing the
    adoption of the inflation-maintenance theory. In rejecting it, we explained its
    inconsistency with the theory.
    [I]t is hardly illogical or inconsistent with precedent to find that a statement
    may cause inflation not simply by adding it to a stock, but by maintaining
    it. Were this not the case, companies could eschew securities-fraud liability
    whenever they actively perpetuate (i.e., though affirmative misstatements)
    inflation that is already extant in their stock price, as long as they cannot be
    found liable for whatever originally introduced the inflation. Indeed, under
    23
    Thus, the actual issue is simply whether Goldman’s share price was inflated.
    Goldman argues that the district court made no finding to this effect. We disagree.
    This Court, like every Court of Appeals that has adopted the inflation-
    maintenance theory, has held that if a court finds a disclosure caused a reduction
    in a defendant’s share price, it can infer that the price was inflated by the amount
    of the reduction. See
    id. at 255
    (“The best way to determine the impact of a false
    statement is to observe what happens when the truth is finally disclosed and use
    that to work backward, on the assumption that the lie’s positive effect on the share
    price is equal to the additive inverse of the truth’s negative effect.” (quoting
    
    Glickenhaus, 787 F.3d at 415
    )).
    The district court found that “[t]he inflation was demonstrated on [the
    corrective-disclosure] dates, when the falsity of the misstatements was revealed.”
    In re Goldman, No. 10 Civ. 3461 (PAC), 
    2018 WL 3854757
    , at *2. It also credited Dr.
    Finnerty’s testimony that “the price declines following these corrective disclosures
    Vivendi’s approach, companies (like Vivendi) would have every incentive
    to maintain inflation that already exists in their stock price by making false
    or misleading statements.
    
    Vivendi, 838 F.3d at 258
    .
    24
    were caused by the news of Goldman’s conflicts.”
    Id. We find
    no abuse of
    discretion in the court’s finding that the inflation maintained by Goldman’s
    statements equaled the price drop caused by the corrective disclosures.
    We Decline Goldman’s Request to Narrow the Inflation-
    Maintenance Theory.
    Although these findings satisfy the inflation-maintenance doctrine,
    Goldman asks us to narrow the doctrine’s focus. Under Goldman’s proposed
    revision, what it terms “general statements” would be legally insufficient as
    evidence of price impact. Plaintiffs relying on such statements would be unable
    to invoke the Basic presumption of classwide reliance and would therefore be
    unable to demonstrate under Rule 23(b)(3) that classwide issues (i.e., reliance on
    the defendant’s misstatements) predominate over individual issues.
    Goldman’s theory is as follows. In its view, “[c]ourts have applied the
    narrow price maintenance theory only in two ‘special circumstances.’” Appellant
    Br. 35 (citation omitted). 9 The first is “‘unduly optimistic statement[s]’ about
    9Although Goldman repeatedly frames inflation maintenance as a “narrow” alternative
    to inflation introduction, this is incorrect. In the wake of the Supreme Court’s 2014
    decision in Halliburton II, securities plaintiffs invoked the inflation-maintenance theory in
    20/28 (71%) of federal district court cases involving a defendant’s attempt to rebut the
    25
    specific, material financial or operational information made to ‘stop[] a [stock]
    price from declining.”
    Id. (quoting Schleicher
    v. Wendt, 
    618 F.3d 679
    , 683 (7th Cir.
    2010)). The second is statements “falsely ‘convey[ing] that the company ha[s] met
    market expectations’ about a specific, material financial metric, product, or event.”
    Id. (quoting In
    re Scientific-Atlanta, Inc. Sec. Litig., 
    571 F. Supp. 2d 1315
    , 1340–41
    (N.D. Ga. 2007)).         Unsurprisingly, Goldman argues that neither special
    circumstance accounts for the alleged misstatements at issue here.
    In effect, what Goldman has done is surveyed nationwide inflation-
    maintenance cases (some Rule 23 decisions, some not), claimed that each case fits
    one of its special circumstances, and thereby concluded that these are the only
    permissible applications of the theory. The problem for Goldman is that none of
    these cases held that the inflation-maintenance theory applies so narrowly, at the
    Rule 23 stage or otherwise. Nor do they distinguish “general” statements from
    Basic presumption. See Note, Congress, the Supreme Court, and the Rise of Securities-Fraud
    Class Actions, 132 Harv. L. Rev. 1067, 1077 (2019). In all twenty of those cases, the district
    court held that the defendant failed to rebut the Basic presumption.
    Id. 26 “specific”
    ones. They simply apply the theory, which every Court of Appeals to
    adopt it has held covers all material misstatements, to the facts before them.10
    Goldman concedes that ATRS I “did not address whether general
    statements, like those challenged here, are capable of maintaining inflation in a
    stock price as a matter of law” for the purpose of class certification.
    Id. at 48.
    It
    characterizes the issue as one of “first impression in this Circuit.”
    Id. In its
    view,
    we should adopt this rule because the Supreme Court’s decision in Halliburton II
    allows lower courts to consider evidence of price impact at the Rule 23 stage, and
    so-called general statements like those at issue here “are incapable of maintaining
    inflation in a stock price for the same reasons that those statements are immaterial
    as a matter of law (as well as fact).”
    Id. (citing Halliburton
    II, 573 U.S. at 283
    ).
    We reject Goldman’s proposed revision of our inflation-maintenance
    doctrine.
    10It is unsurprising that Goldman’s survey of Rule 23 cases did not uncover ones
    involving truly general statements. As explained below, courts regularly dismiss
    securities claims predicated on such statements under Rule 12(b)(6) because they are too
    immaterial to induce reliance. Because courts virtually never entertain contested Rule 23
    motions prior to the conclusion of the pleading stage, class certification opinions rarely
    involve what Goldman deems to be impermissibly general statements. Put differently,
    Rule 12(b)(6) weeds out unmeritorious cases before they ever get to the Rule 23 stage.
    27
    As noted earlier, one of the elements a securities plaintiff must prove to
    succeed on her claim is that the defendant’s misstatements were “material”
    enough to induce the reliance of reasonable shareholders. But “materiality . . . is
    not an appropriate consideration at the class certification stage.” ATRS 
    I, 879 F.3d at 486
    . “Because a failure of proof on the issue of materiality . . . does not give rise
    to any prospect of individual questions overwhelming common ones, materiality
    need not be proved prior to Rule 23(b)(3) class certification.” Amgen Inc. v.
    Connecticut Ret. Plans & Tr. Funds, 
    568 U.S. 455
    , 474 (2013).11
    Goldman is not formally asking for a materiality test. But its “special
    circumstances” test would commandeer the inflation-maintenance theory by
    essentially requiring courts to ask whether the alleged misstatements are, in
    11Goldman argues that it can challenge materiality at the Rule 23 stage. In its view, Amgen
    held only that Rule 23 courts “need not” consider materiality, not that they may not do so.
    To whatever extent Amgen is ambiguous, Halliburton II is clear that Rule 23 courts may not
    consider materiality. 
    See 573 U.S. at 282
    (“[M]ateriality . . . should be left to the merits stage,
    because it does not bear on the predominance requirement of Rule 23(b)(3).” (emphasis
    added)). And ATRS I conclusively settled the matter in this circuit.
    28
    Goldman’s words, “immaterial as a matter of law.” Appellant Br. 48. This is the
    precise question posed by materiality. 12
    Goldman’s authority for what constitutes an impermissibly “general
    statement” provides further evidence that its “special circumstances” test is really
    a means for smuggling materiality into Rule 23. Its brief contains a table of nearly
    a dozen cases holding that “general statements . . . about business principles and
    conflicts controls are too general to cause a reasonable investor to rely upon them.”
    Id. at 43–46
    (quotation marks and citation omitted). But every one of these cases
    is the dismissal of a securities claim under Rule 12(b)(6) on the ground that the
    alleged misstatements were too general to be material.13 None of them concern
    12 See, e.g., United States v. Litvak, 
    808 F.3d 160
    , 175 (2d Cir. 2015) (“Where the
    misstatements are so obviously unimportant to a reasonable investor that reasonable
    minds could not differ on the question of their importance, we may find the
    misstatements immaterial as a matter of law.” (emphasis added, quotation marks and
    citation omitted)).
    13See, e.g., In re UBS AG Sec. Litig., No. 07 Civ. 11225 (RJS), 
    2012 WL 4471265
    , at *36
    (S.D.N.Y. Sept. 28, 2012) (holding on a motion to dismiss that “the statements are non-
    actionable puffery and do not constitute material misstatements”), aff’d sub nom., 
    752 F.3d 173
    (2d Cir. 2014); Indiana Pub. Ret. Sys. v. SAIC, Inc., 
    818 F.3d 85
    , 97–98 (2d Cir. 2016)
    (holding on a motion to dismiss the challenged statements do not “ris[e] to the level of
    materiality required to form the basis for assessing a potential investment”).
    29
    the issue here of whether so-called general statements that made it past the
    pleading stage can survive under Rule 23.
    Of course, just because something looks like materiality does not mean it is
    materiality. Price impact also resembles materiality, but defendants may attempt
    to disprove it at class certification. See Halliburton 
    II, 573 U.S. at 282
    . But here, we
    need not elevate function over form. There are three compelling reasons for
    rejecting Goldman’s argument.
    First, and most fundamentally, Goldman’s proposed rule is difficult to
    square with Rule 23(b)(3). Whether alleged misstatements are too general to
    demonstrate price impact has nothing to do with the issue of whether common
    questions predominate over individual ones. While Goldman’s test might weed
    out potentially unmeritorious claims, Rule 23 is not a weed whacker for merits
    problems. As the Supreme Court explained in Amgen:
    Although we have cautioned that a court’s class-certification analysis
    must be “rigorous” and may “entail some overlap with the merits of
    the plaintiff’s underlying claim,” Wal-Mart Stores, Inc. v. Dukes, 
    564 U.S. 338
    , 351 (2011) (internal quotation marks omitted), Rule 23 grants
    courts no license to engage in free-ranging merits inquiries at the
    certification stage. Merits questions may be considered to the extent—
    but only to the extent—that they are relevant to determining whether
    the Rule 23 prerequisites for class certification are satisfied.
    
    30 568 U.S. at 465
    –66 (emphasis added). 14 This is why materiality is irrelevant at the
    Rule 23 stage. Win or lose, the issue is common to all class members.
    Id. at 468.
    The same is true here, in no small part because Goldman’s test is materiality
    by another name. If general statements cannot maintain price inflation because no
    reasonable investor would have relied on them, then the question of inactionable
    generality is common to the class. For that reason, “the class is entirely cohesive:
    It will prevail or fail in unison. In no event will the individual circumstances of
    particular class members bear on the inquiry.”
    Id. at 460.
    Second, Goldman’s formulation of the inflation-maintenance theory is at
    odds with Vivendi. That opinion, relying on the Seventh and Eleventh Circuits
    whose doctrine it adopted, noted that “theories of ‘inflation maintenance’ and
    ‘inflation introduction’ are not separate legal categories.’” 
    Vivendi, 838 F.3d at 259
    (quoting 
    Glickenhaus, 787 F.3d at 418
    ). 15 Goldman’s proposed rule, by applying
    only to inflation-maintaining statements, would make inflation maintenance and
    See also, e.g., Sykes v. Mel S. Harris & Assocs. LLC, 
    780 F.3d 70
    , 81 (2d Cir. 2015) (applying
    14
    Amgen’s rule); Fezzani v. Bear, Stearns & Co. Inc., 
    777 F.3d 566
    , 569–70 (2d Cir. 2015) (same).
    15See also 
    Vivendi, 838 F.3d at 259
    (quoting 
    FindWhat, 658 F.3d at 1316
    , for the proposition
    that “[t]here is no reason to draw any legal distinction between fraudulent statements
    that wrongfully prolong the presence of inflation in a stock price and fraudulent
    statements that initially introduce that inflation”).
    31
    inflation introduction “separate legal categories.” Goldman points to no authority
    holding that “general statements” like those supposedly at issue here are legally
    insufficient to establish inflation introduction.
    Third, this Court has implicitly rejected Goldman’s “special circumstances”
    test. Waggoner, a Rule 23(f) appeal allowing shareholder plaintiffs to invoke the
    inflation-maintenance theory, involved claims that a high-ranking Barclays trader
    told a magazine that it “monitored activity in [a certain high-frequency exchange]
    and would remove traders who engaged in conduct that disadvantaged [its]
    
    clients.” 875 F.3d at 87
    . The trader elsewhere stated that the high-frequency
    system was “built on transparency” and “had safeguards to manage toxicity, and
    to help its institutional clients understand how to manage their interactions with
    high-frequency traders.”
    Id. (citation, quotation
    marks, and brackets omitted).
    It is true that Barclays’ statements were about a specific high-frequency
    exchange, while Goldman’s challenged statements were more generally about its
    controls for handling conflicts of interest. But Goldman’s alleged lack of, or
    disregard for, these controls is the specific problem that led to the corrective
    disclosures. See, e.g., J.A. 5716 (quoting Goldman as alleging to have “extensive
    procedures and controls that are designed to identify and address conflicts of
    32
    interest”). That Barclays mentioned a specific exchange does little to distinguish
    its statements from those at issue here; each is an alleged misrepresentation about
    general business practices.
    ***
    We are not blind to the widespread understanding that class certification
    can pressure defendants into settling large claims, meritorious or not, because of
    the financial risk of going to trial. See, e.g., In re Rhone-Poulenc Rorer Inc., 
    51 F.3d 1293
    , 1298 (7th Cir. 1995) (Posner, J.). Rule 23’s in terrorem effect is the reason
    Congress authorized interlocutory appeals under Rule 23(f). See Fed R. Civ. P. 23
    advisory committee’s note (1998).
    Referencing these legitimate policy concerns, Goldman argues that rejecting
    its theory would open the floodgates to unmeritorious litigation by allowing
    courts to certify classes that it believes should lose on the merits. Specifically, it
    argues that “[i]f allegations of misconduct caused a stock to drop, then investor
    plaintiffs could just point to any general statement about the company’s business
    principles or risk controls and proclaim ‘price maintenance.’” Appellant Br. 52–
    53.
    33
    This would indeed be troubling. But our law already beats back this parade
    of horribles in three meaningful ways.
    First, materiality challenges are fair game under Rule 12(b)(6). Dismissal at
    that early stage of the litigation prevents the case from ever reaching Rule 23. As
    Goldman’s table of materiality cases demonstrates, courts regularly dismiss
    securities complaints because the challenged statements were too general to have
    induced reliance. In fact, the district court in this case dismissed some of the alleged
    misstatements for this very reason. See 
    Richman, 868 F. Supp. 2d at 274
    . As to the
    statements before us now, the court rejected Goldman’s materiality challenge,
    holding that the shareholders plausibly stated a claim for securities fraud.
    Id. at 279–80.
    Right or wrong, we lack the authority to review that decision at this time. 16
    Rule 23 does not give defendants a do-over on materiality. 17
    Second, the Federal Rules of Civil Procedure do offer securities defendants a
    do-over on materiality prior to trial: summary judgment. Goldman has already
    moved for summary judgment in the court below. See District Court Docket, ECF
    16   We express no opinion on whether the misstatements at issue here are material.
    17Defendants may also, as Goldman did here, seek a district court’s permission to take an
    interlocutory appeal from decisions denying motions to dismiss on materiality grounds.
    34
    No. 168 (Nov. 6, 2015). One of its arguments is that the alleged misstatements are
    immaterial as a matter of law. See
    id. at 15–17.
    Third, even though defendants may not challenge materiality at the Rule 23
    stage, they may present evidence to disprove price impact when seeking to rebut
    the Basic presumption. Here, for example, Goldman presented event studies and
    testimony from multiple experts.         The district court found this evidence
    insufficient—a finding we turn to momentarily. But in appropriate cases, courts
    will decline to certify classes on this ground.
    In sum, while securities class action defendants have numerous avenues for
    challenging materiality, Rule 23 is not one of them. The inflation-maintenance
    theory does not discriminate between general and specific misstatements.
    II.    The District Court Did Not Abuse Its Discretion by Holding that
    Goldman Failed to Rebut the Basic Presumption by a
    Preponderance of the Evidence.
    Goldman’s second argument is that the district court abused its discretion
    in holding that Goldman failed to rebut the Basic presumption. To the extent a
    “ruling on a Rule 23 requirement is supported by a finding of fact, that finding is

    Metromedia Litig.,

    , 480 (2d Cir. 2008), abrogated on other grounds by
    Amgen, 
    568 U.S. 455
    .
    The plaintiff bears the initial burden of demonstrating that the prerequisites
    for the Basic presumption are met. 
    Waggoner, 875 F.3d at 95
    . The prerequisites a
    plaintiff must prove prior to class certification are “that [the] defendants’
    misstatements were publicly known, their shares traded in an efficient market, and
    [the] plaintiffs purchased the shares at the market price after the misstatements
    were made but before the truth was revealed.” ATRS 
    I, 879 F.3d at 481
    ; see
    Halliburton 
    II, 573 U.S. at 268
    , 276. Goldman conceded in the prior appeal that
    these prerequisites are met here. ATRS 
    I, 879 F.3d at 484
    .
    Once the plaintiff makes this showing, § 10(b)’s reliance requirement is
    presumptively satisfied. 
    Waggoner, 875 F.3d at 95
    . At that point, the burden shifts
    to the defendant to rebut the presumption.
    Id. at 101–03.
    It may do so by showing,
    by a preponderance of the evidence, that the entire price decline on the corrective-
    disclosure dates was due to something other than its alleged misstatements.
    “[M]erely suggesting that another factor also contributed to an impact on a
    security’s price does not establish that the fraudulent conduct complained of did
    36
    not also impact the price of the security.”
    Id. at 105.
    18 The plaintiff may also, as
    the shareholders did here, present evidence of price impact to demonstrate the
    shortcomings of the defendant’s rebuttal evidence. But it bears repeating that to
    invoke Basic, the shareholders need not prove price impact directly. See Halliburton
    
    II, 573 U.S. at 277
    –79.
    As outlined above, the district court applied the preponderance standard,
    credited the shareholders’ expert’s theory, and rejected the theories of Goldman’s
    experts. Goldman argues that the court (A) erroneously construed Goldman’s
    rebuttal evidence and (B) misapplied the preponderance standard in holding that
    Goldman failed to rebut the Basic presumption.
    18Although this rule places a heavy burden on defendants, a more relaxed alternative
    would be illogical under Basic. If a corrective disclosure decreases a defendant’s share
    price on a given date, the plaintiffs have a claim for securities fraud. That other events
    may have also decreased the share price on that date does not change this fact; it simply
    complicates the task of determining the effect of the corrective disclosure by creating a
    need to isolate it from the effects of the other events. By presuming reliance when its
    prerequisites are satisfied, Basic places the burden of untangling these events on the
    defendant. Thus, for a defendant to erase the inference that the corrective disclosure had
    price impact—i.e., that it played some role in the price decline—it must demonstrate
    under the preponderance-of-the-evidence standard, using event studies or other means,
    that the other events explain the entire price drop.
    37
    The District Court Did Not Misconstrue Goldman’s
    Evidence in Holding that It Failed to Rebut the Basic
    Presumption.
    Because the Basic presumption applies, Goldman bears the burden of
    rebutting it. It must show by a preponderance of the evidence that the entire price
    decline on the corrective-disclosure dates was due to something other than the
    corrective disclosures. See 
    Waggoner, 875 F.3d at 105
    . Goldman challenges the
    district court’s finding that its evidence was insufficient to satisfy this burden.
    1. Goldman’s primary contention is that the district court clearly erred by
    “ignor[ing] the substance of [the] press reports” preceding the corrective
    disclosures that touched on its conflicts. Appellant Br. 62. In Goldman’s view, the
    market’s nonreaction to these reports proved that it was indifferent to the
    revelation that Goldman’s statements about being conflict free were untrue.
    The district court reviewed each of the news reports and concluded by a
    preponderance of the evidence that “[t]he absence of price movement [on these
    dates], . . . in and of itself, is not sufficient to sever the link between the first
    corrective disclosure and the subsequent stock price drop.” In re Goldman, No. 10
    Civ. 3461 (PAC), 
    2018 WL 3854757
    , at *4. This was because the disclosures, and
    particularly the initial Abacus complaint, “included new material information that
    38
    had not been described in any of the 36 more generic reports on conflicts.”
    Id. This newly
    revealed “hard evidence of Goldman’s client conflicts” included “direct
    quotes from damning emails . . . [and] internal memoranda,” as well as details
    about “the manner in which Goldman . . . hid[] Paulson’s role in asset selection.”
    Id. at *4
    –5. The court also noted that because these details were “disclosed by a
    federal government agency,” they were “obviously . . . more reliable and credible
    than any of the 36 media reports, especially in the presence of the denials and
    rebuttals that accompanied some of the reports.”
    Id. at *4
    . 
    The court further found
    that some of the reports “were not damaging or revelatory, but rather
    commendatory” praise of Goldman’s risk management.
    Id. at *4
    n.6.
    We find no clear error in the district court’s weighing of the evidence. The
    court applied the correct legal standard and reasonably concluded by a
    preponderance of the evidence that the corrective disclosures revealed new and
    material information to the market. Goldman has no persuasive response to the
    court’s findings that the “hard evidence” first revealed in the corrective
    disclosures moved the market in a way that the news reports did not.
    Although it is possible that Goldman’s price declined in part because the
    market feared that Goldman would be fined, this is not enough to rebut the Basic
    39
    presumption. Moreover, there are good reasons to believe that the corrective
    disclosures were more significant than Goldman makes them out to be. Because
    the inflation-maintenance theory asks “what would have happened if [the
    defendant] had spoken truthfully,” 
    Vivendi, 838 F.3d at 258
    , Goldman’s burden is
    to show that the market would not have reacted had Goldman told the truth about
    its alleged failure to manage its conflicts. It is difficult to imagine that Goldman’s
    shareholders would have been indifferent had Goldman disclosed its alleged
    failure to prevent employees from illegally advising clients to buy into CDOs that
    were built to fail by a hedge fund secretly shorting the investors’ positions. It is
    therefore reasonable to assume that this disclosure would have harmed
    Goldman’s reputation, causing at least some of its clients and potential clients to
    seriously reconsider trusting Goldman with their money. This lost revenue would
    have reduced Goldman’s bottom line and caused the market to devalue its share
    price accordingly. These adverse consequences have nothing to do with the threat
    of enforcement actions, and everything to do with how Goldman managed its
    conflicts of interest.
    2. Goldman also argues that the district court did not “address the generality
    of [the corrective disclosures other than the Abacus complaint].” Appellant Br. at
    40
    62–63. In its view, these disclosures were “far less detailed than the press reports
    of client conflicts.”
    Id. at 63.
    It is true that the district court focused largely on the Abacus complaint. But
    so did Goldman. As the court found, Dr. Choi “performed no event study
    concerning stock price declines following the [other] corrective disclosures.” In re
    Goldman, No. 10 Civ. 3461 (PAC), 
    2018 WL 3854757
    , at *5. The burden of rebutting
    the Basic presumption was on Goldman, not the district court. The court’s finding
    that the Abacus disclosure had a price impact suffices at this stage for the reasons
    noted above.
    3. Finally, Goldman makes a one-paragraph argument that the district court
    misconstrued Dr. Choi’s event study. As noted above, the court found extensive
    flaws with Dr. Choi’s study and gave little weight to his conclusions.
    Goldman does not meaningfully engage with the district court’s detailed
    rejection of Dr. Choi’s report. Its most substantial argument is that the court
    erroneously found that Dr. Choi’s opinion rested on “the premise that the first
    price decline is consistent with price declines that four other companies previously
    experienced upon the news of similar enforcement events.”
    Id. Goldman argues
    that Dr. Choi actually concluded that the price declines were “not statistically
    41
    significantly different.” Appellant Br. 67. Even if the court mistakenly referred to
    consistency rather than a lack of statistically significant difference—and elsewhere
    it used the “statistically different” terminology, see In re Goldman, No. 10 Civ. 3461
    (PAC), 
    2018 WL 3854757
    , at *3—the difference is splitting hairs. Goldman does
    not clearly explain how this subtle difference in terminology renders clearly
    erroneous the court’s extensive reasons for rejecting Dr. Choi’s conclusions. Nor
    do Goldman’s remaining arguments point to an abuse of discretion.
    The District Court Correctly Applied the Preponderance
    Standard in Weighing the Evidence of Price Impact.
    Although Goldman bears the burden of persuasion, it focuses heavily on the
    supposed lack of evidence the shareholders introduced to undermine its
    contention that its statements had no price impact. 19
    1. Goldman first contends that the shareholders “submitted no evidence of
    fraud-induced inflation in Goldman Sachs’ stock price that the challenged
    statements maintained.” Appellant Br. 55. Thus, Goldman argues, the district
    19That Goldman focuses on the shareholders’ evidence, and the district court began its
    analysis with this evidence, should not obscure the fact that Goldman bears the burden
    of persuasion at this stage. Once the shareholders successfully invoke Basic, which
    happened here, the question is not which side has better evidence, but whether the
    defendant has rebutted the presumption.
    42
    court’s finding that the shareholders invoked Basic rested on allegations, rather
    than evidence. As explained above, we reject Goldman’s contention that the
    shareholders were required to submit evidence of “fraud-induced” inflation. We
    therefore take Goldman’s argument as one that the shareholders failed to submit
    any evidence of price inflation.
    We noted in Part I that “[t]he best way to determine the impact of a false
    statement is to observe what happens when the truth is finally disclosed and use
    that to work backward, on the assumption that the lie’s positive effect on the share
    price is equal to the additive inverse of the truth’s negative effect.” 
    Vivendi, 838 F.3d at 255
    (quoting 
    Glickenhaus, 787 F.3d at 415
    ). This is precisely what the district
    court did:
    The Court accepts Dr. Finnerty’s [the shareholders’ expert] opinion
    that the news of Goldman’s conflicts on the . . . corrective disclosure
    dates negatively impacted Goldman’s stock price. It is only natural
    that “economically significant negative news,” such as these, would
    at least contribute to the stock price declines. Defendants attempt to
    undermine Dr. Finnerty’s opinion, claiming in part that the
    underlying damages model is “completely made up.” That overstates
    the matter. Dr. Finnerty’s model, at the very least, establishes a link between
    the news of Goldman’s conflicts and the subsequent stock price declines.
    That is sufficient.
    43
    In re Goldman, No. 10 Civ. 3461 (PAC), 
    2018 WL 3854757
    , at *4 (emphasis added,
    citations omitted).
    We thus find no merit in Goldman’s contention that the district court
    accepted Dr. Finnerty’s model at face value or that it credited mere allegations. 20
    The court reviewed the evidence, traced the price declines back to Goldman’s
    alleged misstatements, and credited Dr. Finnerty’s report.               For Goldman’s
    In critiquing the district court’s purported lack of findings, Goldman homes in on the
    20
    word “allegedly” in the following passage:
    [The shareholders] claim that the alleged misstatements had impact on
    Goldman’s stock price. Although the misstatements themselves did not
    inflate the stock price, they allegedly served to maintain an already inflated
    stock price. The inflation was demonstrated on [several] dates, when the
    falsity of the misstatements was revealed . . . .
    In re Goldman, No. 10 Civ. 3461 (PAC), 
    2018 WL 3854757
    , at *2. This language leads
    Goldman to conclude that the “[district court] gave no indication that it actually weighed
    competing evidence or found facts,” and instead “accepted at face value [the
    shareholders’] and their expert’s ‘alleg[ation]’ that the challenged statements ‘served to
    maintain an already inflated stock price.” Appellant Br. 55 (citation omitted). But
    Goldman misreads the district court’s opinion. The language it quotes unremarkably
    lacks factual conclusions because it is from an impartial summary of the shareholders’
    evidence—what one might call the facts section of the opinion. The court saved its
    conclusions for the analysis section, where, as we have found, it made the necessary
    findings.
    44
    argument to have any force, it would need to show that the court clearly erred by
    accepting Dr. Finnerty’s findings. Goldman has failed to make this showing. 21
    2. Goldman also argues that the news of its alleged conflicts could not have
    caused its share price to decline on the corrective-disclosure dates because its
    alleged misstatements were “consistent” with the later-revealed fact that it had
    significant conflicts of interest. Specifically, Goldman contends that statements
    such as “potential or perceived conflicts could give rise to litigation or enforcement
    actions,” J.A. 5716, “expressly warned” the market that it might have conflicts,
    meaning the market should not have been surprised to learn that Goldman was in
    fact conflicted, Appellant Br. 61. This is doubtful. In effect, Goldman is arguing
    that a reasonable investor would have believed its vague statement was
    “consistent” with the revelation that it allegedly failed to prevent its employees
    from colluding with hedge funds to trick investors into buying risky securities.
    The district court did not abuse its discretion by rejecting that theory.
    21Goldman additionally asserts that Dr. Finnerty’s testimony implied that on one date,
    “70% of Goldman Sachs’ $20.6 billion market capitalization was ‘inflation’ maintained by
    [the alleged misstatements].” Appellant Br. 58. The shareholders accuse Goldman of
    cherry picking this data point using a date from the height of the financial crisis. We find
    no clear error in the district court’s decision to choose one reasonable interpretation of
    the evidence over another.
    45
    Goldman is free to make its merits arguments at summary judgment or trial.
    The issue here is simply whether the district court abused its discretion by finding
    that Goldman failed to rebut the Basic presumption by a preponderance of the
    evidence. We find no abuse of discretion in the court’s reasonable conclusion that
    Goldman failed to meet this burden.
    III.   The Dissent
    Our colleague Judge Sullivan disagrees with our ultimate conclusion. In his
    view, Goldman and its co-defendants “offered persuasive and uncontradicted
    evidence that Goldman’s share price was unaffected by earlier disclosures of
    Defendants’ alleged conflicts of interest.” Dissent Op. at 1. But the issue before us
    is not whether Judge Sullivan was persuaded; that task fell to Judge Crotty who
    conducted the hearing, heard the testimony, carefully reviewed all the evidence
    and analyzed the conclusions of the experts. Unlike Judge Sullivan, Judge Crotty
    was not persuaded. Judge Crotty was clear in his reasoning and we have reviewed
    it at length in our opinion through the lenses of clear error, abuse of discretion and
    Goldman’s burden. 
    See supra
    at 15–19, 36–46.
    We also disagree with our colleague’s characterization that Goldman’s
    evidence was “uncontradicted.” Goldman bore the burden of rebutting the Basic
    46
    presumption. Judge Crotty concluded that Goldman’s proffer simply came up
    short.   The shareholders pointed out, through their expert and through
    comparisons of the news stories on which Goldman tied its fate here, that the
    conclusions of Goldman’s experts were wanting if there were not equivalencies
    between the news stories and the “corrective disclosures.” 22 Judge Crotty agreed
    with the shareholders; his opinion reflects his reasoning in this regard. The
    majority opinion reviews that reasoning and finds it to have a firm basis in the
    facts of the record.      Our dissenting friend points to no inaccuracies or
    misstatements of the evidence to support his view that the district court’s
    conclusions were so clearly erroneous that they require appellate correction. It
    might well be that were one of us given the same task as that of the district judge
    we would conclude otherwise; but we cannot say there can only be one conclusion
    from the record presented.
    22The dissent is quite critical of Judge Crotty’s (and our) “failure to engage” with Dr.
    Choi’s analysis. See Dissent Op. at 6. Our colleague must have overlooked our
    description of Judge Crotty’s concerns about Dr. Choi’s data—Dr. Choi examined only
    one of three disclosures—and Dr. Choi’s employment of factors in his analysis that Dr.
    Choi himself conceded were not “generally accepted in the field.” In re Goldman, No. 10
    Civ. 3461 (PAC), 
    2018 WL 3854757
    , at *5–6. Judge Crotty had other concerns with the
    value of Dr. Choi’s analysis as set forth above. 
    See supra
    at 17–19.
    47
    Lastly, our colleague seems exceptionally eager to take on “the generic
    statements on which [the shareholders’] claims are based.” Dissent Op. at 8. His
    assertion that those statements are too general as a matter of law seems to endorse
    Goldman’s view that price maintenance cases are limited to more specific
    statements related to performance or corporate expectations. We disagree and
    have explained why in our opinion. 23
    What the dissent really wants to do is to revisit the question of whether the
    statements are too general as a matter of law to be deemed material. Judge
    Sullivan would inject materiality into our Rule 23 analysis in the name of limiting
    the types of statements that can be considered for price maintenance. 24 The
    question of whether the statements on which plaintiffs rely were not material as a
    matter of law will be addressed by the district court at an appropriate time. But
    23   
    See supra
    Section I.B.
    24The fact is that this argument is just a redux of Goldman’s unsuccessful Rule 12(b)(6)
    argument to dismiss and its motion to reconsider that loss in the district court. “[T]he
    Court cannot say that Goldman’s statements that it complies with the letter and spirit of
    the law and that its success depends on such compliance, its ability to address ‘potential’
    conflict of interests, and valuing its reputation, would be so obviously unimportant to a
    reasonable investor.” 
    Richman, 868 F. Supp. 2d at 280
    ; see also In re Goldman, No. 10 Civ.
    3461 (PAC) 
    2014 WL 2815571
    at *2–6.
    48
    for now, the procedural posture of the case and our understanding of binding
    precedent from this Court and the Supreme Court preclude reaching the matter.
    If acknowledging that limitation while further recognizing that some (but perhaps
    not all) 25 will view the merits of the shareholders’ claim through our colleague’s
    lens is “tiptoeing,” see Dissent Op. at 8–9, then so be it. Careful footwork is often
    required in intricate judicial tasks.
    CONCLUSION
    We AFFIRM the judgment of the district court and REMAND for further
    proceedings consistent with this opinion.
    25 One wonders if the folks who bought Goldman shares, thinking that Goldman
    assiduously guarded against conflicts of interests in its dealings with those it advised on
    financial matters, would be concerned not only with the fines the SEC and DOJ had in
    mind once specific details of Goldman’s fiduciary failures came to light, but also with the
    financial implications to Goldman’s bottom line once those who took Goldman’s advice
    knew it was tainted and had cost them millions or billions of losses in worthless
    Goldman-endorsed investments. Goldman’s specific assertions that it was conflict free
    might be seen as connected to a decision to buy, or hold on to, Goldman stock. 
    See supra
    at 40–41.

    RICHARD J. SULLIVAN, Circuit Judge, dissenting:
    It is difficult to criticize the majority’s cogent and highly logical opinion,
    except to suggest that it perhaps misses the forest for the trees. In my view, the
    district court misapplied the Basic presumption in its analysis of price impact,
    essentially turning the presumption on its head. Because Defendants offered
    persuasive and uncontradicted evidence that Goldman’s share price was
    unaffected by earlier disclosures of Defendants’ alleged conflicts of interest –
    thereby severing the link that undergirds the Basic presumption – I would reverse
    the lower court’s ruling and decertify the class.
    As an initial matter, I agree with the majority’s conclusion in Section I that
    the district court did not misapply the inflation-maintenance theory of price
    impact. Whatever the merits or flaws of that theory, it is clearly the law of this
    circuit and not for this panel to revisit. See In re Vivendi Sec. Litig., 
    838 F.3d 223
    , 258
    (2d Cir. 2016). Nevertheless, I believe that the majority uncritically accepted the
    district court’s conclusions regarding what rebuttal evidence is necessary to
    overcome the Basic presumption. Though the Basic standard is well-established, it
    bears repeating: “[I]f a plaintiff shows that the defendant’s misrepresentation was
    public and material and that the stock traded in a generally efficient market, he is
    entitled to a presumption that the misrepresentation affected the stock price;”
    moreover, “if the plaintiff also shows that he purchased the stock at the market
    price during the relevant period, he is entitled to a further presumption that he
    purchased the stock in reliance on the defendant’s representation.” Halliburton Co.
    v. Erica P. John Fund, Inc. (Halliburton II), 
    573 U.S. 258
    , 279 (2014). Once the Basic
    presumption has been invoked, however, a defendant may then rebut it “through
    ‘any showing that severs the link between the alleged misrepresentation and either
    the price received (or paid) by the plaintiff, or his decision to trade at a fair market
    price.’” Waggoner v. Barclays PLC, 
    875 F.3d 79
    , 95 (2d Cir. 2017) (emphasis added)
    (quoting Halliburton 
    II, 573 U.S. at 269
    ).
    In support of its initial opposition to class certification, Goldman did not
    dispute that Plaintiffs were able to invoke the Basic presumption. See Arkansas
    Teachers Ret. Sys. v. Goldman Sachs Grp., Inc. (ATRS I), 
    879 F.3d 474
    , 484 (2d Cir.
    2018). Instead, Goldman argued that it was able to rebut the presumption with
    evidence demonstrating the lack of price impact following earlier disclosures of
    the alleged conflicts.
    Id. The district
    court found that Goldman had not rebutted
    the presumption; we vacated and remanded, directing the district court to
    “determin[e] whether defendants established by a preponderance of the evidence
    2
    that the misrepresentations did not in fact affect the market price of Goldman
    stock.”
    Id. at 486.
    On remand, the district court held an evidentiary hearing at which Goldman
    offered the testimony of two experts to demonstrate that the alleged misstatements
    did not affect the stock price. The first, Dr. Paul Gompers, testified that 36 news
    reports – including stories on the front pages of The New York Times and The Wall
    Street Journal -- had in fact already revealed the supposed falsity of the alleged
    misrepresentations prior to the three “corrective disclosure” dates, with no
    discernible impact on the price of Goldman’s shares. The second, Dr. Stephen
    Choi, testified that the stock price declined on the corrective disclosure dates
    entirely due to the news that the SEC and Department of Justice had commenced
    enforcement actions against the company – not due to the revelation that Goldman
    had allegedly misrepresented its approach to conflicts of interest, which, as Dr.
    Gompers demonstrated, had already been revealed to the market. Plaintiffs called
    one expert, Dr. John Finnerty, to refute Defendants’ experts’ testimony. Although
    Dr. Finnerty principally testified that the market for Goldman stock was efficient
    – a point that Defendants did not dispute – Dr. Finnerty also conclusorily asserted
    that the 36 earlier news reports did not impact the share price because some of the
    3
    reports included “denials” from Goldman, while others were less detailed than
    the three corrective disclosures alleged in the complaint.
    Based on this testimony and the experts’ reports, the district court
    concluded that Goldman had again failed to rebut the Basic presumption and
    certified the class.   In particular, the district court relied on Dr. Finnerty’s
    testimony, such as it was, to announce that “[t]he absence of price movement
    [following the earlier disclosures] . . . is not sufficient to sever the link between the
    first corrective disclosure [alleged in the complaint] and the subsequent stock price
    drop.” In re Goldman Sachs Grp., Inc. Sec. Litig., No. 10-cv-3461 (PAC), 
    2018 WL 3854757
    , at *4 (S.D.N.Y. Aug. 14, 2018). I disagree.
    First, the district court, and Dr. Finnerty, relied primarily on the “efficient
    market” theory, which alone is insufficient to refute persuasive rebuttal evidence
    regarding the lack of price impact. As set forth in his January 30, 2015 report, Dr.
    Finnerty was retained to determine whether Goldman’s stock traded in an efficient
    market – a necessary precursor to Plaintiff’s invocation of the Basic presumption.
    But Defendants never disputed the efficiency of the market; they presumed as
    much. Rather, they presented evidence of 36 earlier news reports that revealed the
    falsity of the misstatements alleged in the complaint and yet never moved the
    4
    stock price. They argued, without contradiction, that the lack of movement in the
    share price – in an efficient market – proved that the later drop was caused by
    something other than the disclosure of the alleged conflicts of interest. Neither Dr.
    Finnerty nor the district court could refute that conclusion or explain the lack of
    price movement from the earlier disclosures. 1
    Second, Dr. Finnerty made no serious attempt to refute Dr. Choi’s analysis,
    let alone his conclusion that the stock drop was caused by the announcement of
    the SEC and DOJ enforcement actions rather than the underlying factual
    allegations. Instead of differentiating between the price impact of the conflict
    disclosures and the price impact of the enforcement actions, Dr. Finnerty did his
    best to conflate them, arguing that the two were inextricably intertwined. In the
    words of Dr. Finnerty:
    My analysis demonstrates that the description of Goldman’s conduct
    embodied in those three regulatory actions is inextricably tied to the
    actions themselves. To put it at a very simple level, if you were telling
    my students what the take-away is, is you can't have a fraud charge
    without the fraud – without the behavior – and particularly, the SEC
    1 Dr. Finnerty’s attempt to differentiate the 36 news reports from the three corrective
    disclosures by saying that the news reports were accompanied by “denials” from
    Goldman was equally conclusory and unpersuasive, particularly since many of the news
    reports did not include denials at all. See Joint App’x at 5284 –5437; see also
    id. at 3146–96
    (Plaintiffs’ Summary of News Reports);
    id. at 2951–57
    (Defendants’ Summary of News
    Reports).

    enforcement action does lay out the behavior that is the basis for the
    fraud charge.
    Joint App’x at 8196. But this failure to engage with Dr. Choi undermined the very
    purpose of the evidentiary hearing, which was designed to “determin[e] whether
    defendants established by a preponderance of the evidence that the
    misrepresentations did not in fact affect the market price of Goldman stock.”
    ATRS 
    I, 879 F.3d at 486
    . Although the district court was at times highly critical of
    Dr. Choi’s studies, it accepted Dr. Finnerty’s opinions at face value when it
    concluded that “[i]t is only natural that economically significant negative news,
    such as [the conflicts reiterated in the enforcement actions], would at least
    contribute to the stock price declines.” In re Goldman, 
    2018 WL 3854757
    , at *4
    (internal quotation marks omitted). But in addition to being wholly conclusory,
    that observation was largely beside the point, since it offered no clear explanation
    for why the market only moved after the 37th recital of fraud allegations.
    Of course, the majority correctly notes, as we held in Waggoner v. Barclays,
    that Plaintiffs were not required to prove that news of enforcement actions had no
    effect on 
    price. 875 F.3d at 104
    –05. In Waggoner, the plaintiffs – who were also
    proceeding under a price-maintenance theory – invoked the Basic presumption,
    prompting the defendants to argue that the stock price decline “was due to
    6
    potential regulatory action and fines, not the revelation of any allegedly concealed
    truth.”
    Id. at 104
    (internal quotation marks omitted). The district court disagreed,
    and we affirmed, finding that the “record support[ed] the district court’s
    conclusion that such a concern was merely a contributing factor to the decline.”
    Id. In particular,
    we noted that the defendants’ expert conceded that the
    “corrective disclosure . . . may have had a bigger impact on . . . price . . . due to the
    announcement of the New York Attorney General’s lawsuit and that some of the
    price reaction was independent of the specific allegations.”
    Id. (alterations and
    internal quotation marks omitted).
    But the key difference between this case and Waggoner is that Defendants
    here have demonstrated that the prior disclosures – as set forth in 36 separate news
    reports over as many months – had no impact on Goldman’s stock price. Indeed,
    as the district court expressly acknowledged, “Dr. Finnerty concede[d] that
    Goldman's stock price did not move on any of the 36 dates on which the falsity of
    the alleged misstatements was revealed to the public.” In re Goldman, 
    2018 WL 3854757
    , at *4 (emphasis added).        Thus, unlike the defendants in Waggoner,
    Goldman introduced hard evidence that “sever[ed] the link between the alleged
    misrepresentation and . . . the price . . . paid by the plaintiff.” Waggoner, 
    875 F.3d 7
    at 95 (quoting Halliburton 
    II, 573 U.S. at 269
    ). If such evidence can be neutralized
    by the mere assertion that the SEC’s repackaging of those disclosures must have
    “at least contribute[d] to the stock price declines,” In re Goldman, 
    2018 WL 3854757
    ,
    at *4, then the Basic presumption is truly irrebuttable and class certification is all
    but a certainty in every case.
    Finally, I think it’s fair for this court to consider the nature of the alleged
    misstatements in assessing whether and why “the misrepresentations did not in
    fact affect the market price of Goldman stock.” ATRS 
    I, 879 F.3d at 486
    . Although
    the majority concedes that “[p]rice impact . . . resembles materiality” and may be
    “disprove[n] . . . at class certification,” it then strains to avoid looking at the
    statements themselves for fear that such a review amounts to “smuggling
    materiality into Rule 23.” Maj. Op. at 29, 30. I disagree.
    Candidly, I don’t see how a reviewing court can ignore the alleged
    misrepresentations when assessing price impact. Here, the obvious explanation
    for why the share price didn’t move after 36 separate news stories on the subject
    of Goldman’s conflicts is that no reasonable investor would have attached any
    significance to the generic statements on which Plaintiffs’ claims are based. The
    majority tiptoes around this fact, noting on the one hand that “courts regularly
    8
    dismiss securities complaints [at the motion to dismiss stage] because the
    challenged statements were too general to have induced reliance,” while tepidly
    insisting that “[w]e express no opinion on whether the misstatements at issue here
    are material,” since “[r]ight or wrong, we lack the authority to review [the district
    court’s materiality findings] at this time.”
    Id. at 34
    & n.16. I don’t believe that such
    rigid compartmentalization is possible, much less required by Amgen, Halliburton
    II, or ATRS I. Once a defendant has challenged the Basic presumption and put
    forth evidence demonstrating that the misrepresentation did not affect share price,
    a reviewing court is free to consider the alleged misrepresentations in order to
    assess their impact on price. The mere fact that such an inquiry “resembles” an
    assessment of materiality does not make it improper.
    Here, the generic quality of Goldman’s alleged misstatements, coupled with
    the undisputed fact that “Goldman's stock price did not move on any of the 36
    dates on which the falsity of the alleged misstatements was revealed to the public,”
    In re Goldman, 
    2018 WL 3854757
    , at *4, clearly compels the conclusion that the stock
    drop following the corrective disclosures was attributable to something other than
    the misstatements alleged in the complaint.         The most obvious explanation,
    consistent with Dr. Choi’s report, is that the drop was caused by news that the SEC
    9
    and DOJ were pursuing enforcement actions against Goldman. But even without
    Dr. Choi’s testimony, the fact remains that Plaintiffs offered no hard evidence,
    expert or otherwise, to refute Goldman’s proof severing the link between the
    alleged misrepresentation and the price paid by Plaintiffs for Goldman shares. It
    therefore seems clear that Defendants “established by a preponderance of the
    evidence that the misrepresentations did not in fact affect the market price of
    Goldman stock.” ATRS 
    I, 879 F.3d at 486
    .
    Accordingly, I would reverse the finding of the district court with respect to
    the Basic presumption and decertify the class.
