DENNIS, Circuit Judge, concurring in the judgment:

   I concur in the judgment reversing the district court’s certification order, but I do so on grounds

different from those assigned by the majority. I respectfully disagree with the majority as to the issues

upon which it decides the case. Although I ultimately agree that the certification order must be

reversed, I do not believe that the law necessarily prevents the plaintiffs from prosecuting this case

as a class action, and, as I explain below, I would remand the case to the district court for further

consideration of whether the criteria for certification have been satisfied.

   The majority today holds that secondary actors (such as the investment banks involved in this case)

who act in concert with issuers of publicly-traded securities in schemes to defraud the investing public

cannot be held liable as primary violators of Section 10(b) or Rule 10b-5 unless they (1) directly make

public misrepresentations; (2) owe the issuer’s shareholders a duty to disclose; or (3) directly

“manipulate” the market for the issuer’s securities through practices such as wash sales or matched

orders. In doing so, the majority aligns this court with the Eighth Circuit1 and immunizes a broad

array of undeniably fraudulent conduct from civil liability under Section 10(b), effectively giving

secondary actors license to scheme with impunity, as long as they keep quiet.2

   Although, as I explain below, I cannot agree with the majority’s cramped interpretation of the

statutory language of section 10(b), in my view, the majority commits a significant error by even



   1
    See In re Charter Commc’ns, Inc. Sec. Litig., 443 F.3d 987 (8th Cir. 2006).
   2
      The majority notes that the investment banks’ alleged conduct was “hardly praiseworthy,” but it
brushes the significance of its decision to immunize their conduct aside by noting that “[u]ltimately,
. . . the rule of liability must be either overinclusive or underinclusive.” See supra, at ___.

                                                   20
reaching this issue. Because the issue on which the majority opinion bases its decision today — a

significant and unsettled question about the scope of primarily liability under Section 10(b) — is

unnecessary to a determination of whether the plaintiffs have satisfied the prerequisites for

maintaining a class action under Federal Rule of Civil Procedure 23, we should not consider it on this

interlocutory appeal of class certification.

   The investment banks have, however, raised two substantial issues that are related to the district

court’s Rule 23 inquiry. The banks argue that the plaintiffs are not entitled to the fraud-on-the-

market presumption of reliance because they have not satisfied the requirements of this court’s

decision in Greenberg v. Crossroad Systems, Inc., 364 F.3d 657 (5th Cir. 2004),3 and that the district

court erred when it concluded that any defendant found to have knowingly violated the securities laws

could be held jointly and severally liable for all of the plaintiffs’ losses in connection with Enron’s

multi-year fraudulent scheme. Greenberg, in my view, is inconsistent with prior precedents of the

Supreme Court and this court insofar as it purports to relieve securities defendants of the burden of

rebutting the fraud-on-the-market presumption. On the latter point, however, I conclude that the

district court erred by construing too broadly the joint and several liability provision of the Private

Securities Litigation Reform Act of 1995 (the “PSLRA”), 15 U.S.C. § 78u-4. I would remand the

case to the district court to determine whether, applying the correct legal standard, common damages

issues continue to predominate over individual issues and whether the case can be tried in a

manageable fashion.

                                                       I.


   3
    Plaintiffs also seek to rely on the Affiliated Ute presumption of reliance. See Affiliated Ute Citizens of
Utah v. United States, 406 U.S. 128 (1972). I do not disagree with the majority’s conclusion that the Affiliated
Ute presumption does not apply in this case. See supra, at ___.

                                                      21
   Our inquiry on this interlocutory appeal under Rule 23(f)4 is limited to determining whether the

district court erred in certifying the case as a class action. See Bell v. Ascendant Solutions, Inc., 422

F.3d 307, 314 (5th Cir. 2005) (stating that Rule 23(f) permits a party to “‘appeal only the issue of

class certification; no other issues may be raised’”) (quoting Bertulli v. Indep. Ass’n of Cont’l Pilots,

242 F.3d 290, 294 (5th Cir. 2001)). We are not permitted to go beyond the issues necessary to class

certification and rule on the merits of plaintiffs’ claims. See Unger v. Amedisys, Inc., 401 F.3d 316,

321 (5th Cir. 2005) (“Class certification hearings should not be mini-trials on the merits of the class

or individual claims.”); see also Eisen v. Carlisle & Jacquelin, 417 U.S. 156, 177 (1974) (noting that

courts cannot “conduct a preliminary inquiry into the merits of a suit” on class certification).

   It is clear, though, that a district court cannot certify a class action unless it finds that the plaintiffs

have satisfied all of the requirements of Rule 23(a) and of one of the three subsections of Rule 23(b).

To fulfill that obligation, it is often necessary for the district court to go “beyond the pleadings” and

“understand the claims, defenses, relevant facts, and applicable substantive law in order to make a

meaningful determination of the certification issues.” Castano v. Am. Tobacco Co., 84 F.3d 734, 744

(5th Cir. 1996). In addition, to the extent that issues relevant to the ultimate merits of the case are

also necessary to the district court’s determination of one or more of the requirements of Rule 23,

the district court can, and must, consider those issues at the class certification stage. See Bell, 422

F.3d at 311-12; see also In re Initial Pub. Offering Sec. Litig., 471 F.3d 24, 41 (2d Cir. 2006)

    Fed. R. Civ. P. 23(f) provides:

        A court of appeals may in its discretion permit an appeal from an order of a district court
        granting or denying class action certification under this rule if application is made to it within
        ten days after entry of the order. An appeal does not stay proceedings in the district court
        unless the district judge or the court of appeals so orders.

                                                       22
(“[T]here is no reason to lessen a district court’s obligation to make a determination that every Rule

23 requirement is met before certifying a class just because of some or even full overlap of that

requirement with a merits issue.”).5 By the same token, any such issues are also necessarily within

the scope of our review on an interlocutory appeal of a district court’s decision to certify a class.

Like the district court, however, this court can consider issues relevant to the merits of the plaintiffs’

claims only to the extent that such consideration is necessary to determine whether the proposed class

satisfies the requirements of Rule 23. See Initial Pub. Offering, 471 F.3d at 41 (“[A] district judge

should not assess any aspect of the merits unrelated to a Rule 23 requirement.”) (emphasis added).

   In the majority’s view, one of the issues that this court can review on this interlocutory appeal is

the district court’s conclusion that a secondary actor can be held liable as a primary violator of

Section 10(b) and Rule 10b-5 for its participation in a scheme to defraud, even though it does not

make a direct public misrepresentation or have a duty to speak.6 According to the majority, the


   5
    It is important to note that the factual findings made by the district court at the class certification
stage are not binding on the trier of fact at trial. See Initial Pub. Offering, 471 F.3d at 41 (“[T]he
determination as to a Rule 23 requirement is made only for purposes of class certification and is not
binding on the trier of facts, even if that trier is the class certification judge.”); Unger, 401 F.3d at 323
(stating that “the court’s determination for class certification purposes may be revised (or wholly
rejected) by the ultimate factfinder”); Gariety v. Grant Thornton, LLP, 368 F.3d 356, 366 (4th Cir.
2004) (“The findings made for resolving a class action certification motion serve the court only in its
determination of whether the requirements of Rule 23 have been demonstrated.”).
   6
    The district court initially held that secondary actors can be liable under Section 10(b) and Rule
10b-5 based on deceptive acts not involving a direct public misstatement or a duty to speak when it
denied certain defendants’ motions to dismiss the Section 10(b) claims against them. See In re Enron
Corp. Sec., Derivative & ERISA Litig., 235 F. Supp. 2d 549, 590-94 (S.D. Tex. 2002). In its
opinion on class certification, the court reconsidered (and ultimately adhered to) its earlier views in
light of recent developments in the case law, noting that it had “the power to reconsider such
interlocutory decisions.” See In re Enron Corp. Sec., Derivative & ERISA Litig., No. H-01-3624,
2006 U.S. Dist. LEXIS 43146, at *155 n.84 (S.D. Tex. June 5, 2006). The district court did not,
however, indicate at any point that it believed that its decision on that issue was relevant to any
                                                                                               (continued...)

                                                    23
district court’s determination that secondary actors can violate Section 10(b) and Rule 10b-5 by

engaging in “deceptive” acts without making a public misrepresentation or having a duty to speak

implicates Rule 23(b)(3)’s requirement that “questions of law or fact common to the members of the

class predominate over any questions affecting only individual members.” Fed. R. Civ. P. 23(b)(3).

Without that finding, the majority states, the district court could not have concluded that the plaintiffs

were entitled to a classwide presumption of reliance, and individual issues of reliance would

overwhelm the common, classwide issues, rendering class treatment inappropriate. Thus, the majority

variously characterizes the district court’s ruling on the scope of Section 10(b) liability as “integral”

or “critical” to its class certification decision.

   The majority opinion labors to create the impression of a relationship between the district court’s

decision that securities plaintiffs can state a Section 10(b) claim against a secondary actor who did

not make any affirmative misstatements and the issue of whether the plaintiffs are entitled to rely on

the fraud-on-the-market presumption of Basic Inc. v. Levinson, 485 U.S. 224 (1988). According to

the majority, because the banks did not make public misstatements and had no duty to disclose vis-a-

vis Enron’s shareholders, their participation with Enron in fraudulent transactions that lacked any

independent business purpose is beyond the reach of Section 10(b); because the banks’ conduct is not

actionable under Section 10(b), the plaintiffs cannot invoke a classwide presumption of reliance; and

because reliance cannot be presumed on a classwide basis, individual issues of reliance predominate

over common issues. In sum, the upshot of the majority’s reasoning is that plaintiffs are not entitled

to maintain a class action because the conduct for which they seek to recover — to take the



   6
    (...continued)
specific requirement of Rule 23.

                                                     24
majority’s example, Merrill Lynch’s alleged conduct in connection with the so-called “Nigerian

Barges Transaction” — is not actionable under Section 10(b).

   With the reasoning that underlies the majority’s view set out in this manner, it becomes apparent

that any link between the district court’s liability ruling and its application of the fraud-on-the-market

presumption is tangential at best. The question of whether the banks can be subject to Section 10(b)

liability without making public misrepresentations is by no means necessarily related to the

applicability of the fraud-on-the-market presumption of reliance. Although it is true that the fraud-

on-the-market presumption requires that there be a public misrepresentation upon which the market

can rely, in this case, there were certainly public misrepresentations that arose out of the banks’

allegedly fraudulent transactions with Enron; the rub, of course — and the banks’ primary argument

for why they are not subject to Section 10(b) liability — is that Enron, not the banks, conveyed the

misrepresentations to the market. According to the banks, because they made no public statements,

they are, at worst, aiders and abettors of Enron’s fraud. The plaintiffs counter by asserting, among

other things, that the banks’ allegedly fraudulent conduct is not immunized simply because their joint

scheme to defraud affected the market only through Enron’s public statements.

   The majority’s leap to reach and resolve this dispute — which is strictly a question about the

substantive reach of Section 10(b) — at the certification stage overlooks a key fact: Regardless of

whether this court ultimately agrees with the district court that the banks’ alleged actions are

“deceptive” acts within the meaning of Section 10(b), those actions affected the market via Enron’s

public misrepresentations. Thus, this court can determine whether the plaintiffs are entitled to the

fraud-on-the-market presumption without delving into the district court’s decision that the banks’

conduct is covered by Section 10(b). Viewed in this light, there is little doubt that in this case the


                                                   25
element of transaction causation, or reliance, can be satisfied by the market’s reliance on Enron’s

public representations of its financial health and/or its statements about the transactions in question.

See Simpson v. AOL Time Warner Inc., 452 F.3d 1040, 1052 (9th Cir. 2006) (“[A] plaintiff may be

presumed to have relied on th[e] scheme to defraud if a misrepresentation, which necessarily resulted

from the scheme and the defendant’s conduct therein, was disseminated into an efficient market and

was reflected in the market price.”); In re Parmalat Sec. Litig., 376 F. Supp. 2d 472, 509 (S.D.N.Y.

2005) (applying fraud-on-the-market presumption to claims against secondary actors even though

onlyissuer made public misrepresentations to the market). Accordingly, this court can assess whether

a classwide presumption of reliance applies in this case without first considering the district court’s

merits ruling on the scope of Section 10(b) liability. I would therefore find that the latter issue is

beyond the permissible scope of our limited, interlocutory review under Rule 23(f).

   The majority is, of course, correct in some sense — if the banks engaged in no conduct within the

reach of Section 10(b), then the plaintiffs cannot prevail against them in a class action. But the

plaintiffs’ inability to proceed under such circumstances would have nothing to do with the need to

prove reliance on an individual basis. When this court decides, on a common, classwide basis, as the

majority does today, that the banks’ alleged conduct is non-actionable as a matter of law, it is dubious

to then claim that we are actually finding only that individual issues of reliance predominate over

common issues. Under the majority’s reasoning, individual questions of reliance do not predominate;

rather, reliance is simply irrelevant, because no plaintiff can, on an individual or a class basis, establish

that the banks engaged in any actionable conduct.

   The mere fact that the resolution of a merits issue against a putative class of plaintiffs would, by

definition, preclude the maintenance of a class action simply cannot be sufficient to warrant review


                                                    26
of that issue on an interlocutory appeal. Under such a rule, the resolution of any Rule 12(b)(6) issue

would then become fair game for Rule 23(f) review. The D.C. Circuit has rejected just such a “but-

for” approach to Rule 23(f) appeals. In In re: Lorazepam & Clorazepate Antitrust Litigation, 289

F.3d 98, 107 (D.C. Cir. 2002), the court refused to grant a Rule 23(f) appeal despite the petitioner’s

assertions that the plaintiff class members lacked antitrust standing to maintain the suit. In a passage

that is particularly pertinent to this case, the court explained that Rule 23(f) does not permit review

of every issue that, if resolved against the plaintiffs, would destroy the class action:

        Mylan’s effort to recast its Rule 12(b)(6) arguments as a challenge to class
        certification on the ground that a class of direct purchasers lacks antitrust standing,
        is to no avail. That Mylan’s argument as to antitrust standing may dispose of the class
        as a whole and thereby preclude a lawsuit by direct purchasers goes well beyond the
        purpose of Rule 23(f) review because it is unrelated to the Rule 23 requirements. The
        fact that Mylan’s challenge would be dispositive of the class action is not unlike a
        variety of issues of law on the merits of a class action because of the very nature of
        commonality; review of such issues would expand Rule 23(f) interlocutory review to
        include review of any question raised in a motion to dismiss that may potentially
        dispose of a lawsuit as to the class as a whole. This result would inappropriately mix
        the issue of class certification with the merits of a case, which do not warrant
        interlocutory review pursuant to Rule 23(f). What matters for purposes of Rule 23(f)
        is whether the issue is related to class certification itself . . . .

Id. (internal citation omitted).

   The relationship between the banks’ potential Section 10(b) liability and class certification in this

case is no closer than the relationship between antitrust standing and class certification described in

Lorazepam. Despite the majority’s claims to the contrary, as I explained above, whether the banks’

conduct can give rise to a Section 10(b) action under any circumstances need not be decided in order

to determine whether the plaintiffs are entitled to invoke Basic’s presumption of reliance, and it is

therefore not sufficiently related to any of Rule 23’s class action requirements to warrant

interlocutory review.

   Even were it appropriate for this court to consider whether the banks’ alleged conduct can

constitute a primary violation of Section 10(b) and Rule 10b-5, the majority errs by defining the term

“deceptive” in Section 10(b) in an unduly restrictive fashion.

   Based on language gathered from inapposite Supreme Court decisions, the majority opinion

concludes that the Supreme Court has defined “deceptive” in a manner that both departs from the

plain meaning of the word and reduces Section 10(b)’s flexible prohibition on “directly or indirectly”

using or employing any “deceptive device or contrivance”7 to a much more circumscribed prohibition

that applies only to specific misrepresentations or omissions in breach of an affirmative duty to speak.

Having arrived at this narrow definition of deceptive acts, the majority opinion then finds that,

because the banks did not make misrepresentations or have a duty to speak, Section 10(b) does not

reach their conduct, and imposing liability on them would be indistinguishable from the type of aiding

and abetting liability barred by Central Bank of Denver, N.A. v. First Interstate Bank of Denver,

N.A., 511 U.S. 164 (1994).8

   Such a narrow interpretation of Section 10(b) is neither compelled nor justified by Supreme Court

precedent. The majority’s conclusion hinges almost entirely on its determination that a court

considering the reach of Section 10(b) cannot give the term “deceptive” (in the phrase “manipulative


   7
     Section 10(b) also prohibits any “manipulative” device or contrivance, but I do not take issue with the
majority opinion’s conclusion that the banks’ alleged conduct in this case was not “manipulative,” as that term
is used in Section 10(b). See supra, at ___.
   8
     Although this issue is commonly framed as whether liability can be imposed consistent with the Central
Bank decision, Central Bank itself establishes relatively little about the reach of Section 10(b). The plaintiffs
in that case alleged only that Central Bank aided and abetted a violation of Section 10(b); the plaintiffs did not
claim that the bank was liable as a primary violator of the statute. See Central Bank, 511 U.S. at 191
(“Respondents concede that Central Bank did not commit a manipulative or deceptive act within the meaning
of § 10(b).”).

or deceptive device or contrivance”) its commonly understood, or dictionary, meaning,9 because the

Supreme Court has told us that a defendant acts deceptively only if it makes a misrepresentation or

remains silent in the face of a duty to disclose. The majority opinion relies primarily on Chiarella v.

United States, 445 U.S. 222 (1980), and United States v. O’Hagan, 521 U.S. 642 (1997), to support

this narrow view of the statutory language. The majority’s view is not implausible — some

statements in Chiarella, O’Hagan, and other cases can be read together to support the majority’s

position10 — but neither is it compelling, and the passages upon which the majority relies fall far short

of establishing that the Supreme Court has limited Section 10(b)’s prohibition on “deceptive”

practices exclusively to misrepresentations or omissions.

   Neither Chiarella nor O’Hagan purported to hold that a person can never engage in “deceptive”

action through conduct, rather than speech or nondisclosure. In those cases, the Court held that a

person who trades on non-public information violates Section 10(b) only if he breaches a duty to

disclose, either to the source of the information or to the other party to the trade. See O’Hagan, 521

U.S. at 654-56; Chiarella, 445 U.S. at 235.11 Those cases, however, dealt only with insider trading



   9
    Reference to the common, dictionary definition is, incidentally, the approach that the Supreme Court has
used to define the words “manipulative,” “device,” and “contrivance.” See Ernst & Ernst v. Hochfelder, 425
U.S. 185, 199 & nn.20-21 (1976).
   10
     It is unsurprising that the Supreme Court’s decisions generally speak of misrepresentations or omissions,
as they are typically the means through which fraudulent conduct reaches the market. As Judge Kaplan
remarked in Parmalat, “[A]ny deceptive device or practice, other than one involving manipulative trading
activity, logically requires that somebody misrepresent or omit something at some point, even though the device
could entail more than the misrepresentation.” Parmalat, 376 F. Supp. 2d at 497.
   11
     Also central to those cases, however, was the Chiarella court’s observation that entering into a transaction
on the basis of unequal information, while perhaps unfair, is not inherently fraudulent or deceptive in any sense
of those words. See Chiarella, 445 U.S. at 232 (“[N]ot every instance of financial unfairness constitutes
fraudulent activity under § 10(b).”); id. at 233 (“[N]either the Congress nor the Commission ever has adopted
a parity-of-information rule.”).

                                                      29
— the defendants in those cases were prosecuted only for their silence, i.e., their failure to disclose

that they possessed material information that other investors in the market did not possess. Neither

of those cases involved allegations of a multi-party scheme to defraud. Here, by contrast, the

plaintiffs assert that the banks engaged in a scheme with Enron whereby they structured and entered

into wholly fraudulent transactions that were designed for the sole purpose of falsifying Enron’s

financial results. Nothing in Chiarella or O’Hagan forecloses the conclusion that Section 10(b) can

reach “deceptive” conduct that is not in the form of a misrepresentation or omission in cases, like this

one, that involve large-scale schemes to defraud.

   Nor do any of the Supreme Court’s other decisions establish that fraudulent conduct is beyond the

reach of Section 10(b) simply because it affects the market only through the misrepresentations of

another participant in the fraudulent scheme. As noted above, Central Bank itself did not reach this

question because the plaintiffs in that case asserted only that the defendant’s conduct amounted to

aiding and abetting. Moreover, language from other of the Court’s opinions affirmatively indicates

that “deceptive” conduct need not always be in the form of a misrepresentation or an omission. See

Santa Fe Indus., Inc. v. Green, 430 U.S. 462, 475-76 (1977) (explaining that the Court’s prior cases

all “included some element of deception,” and did not “support the proposition . . . that a breach of

fiduciary duty by majority stockholders, without any deception, misrepresentation, or nondisclosure,

violates the statute and the Rule”) (emphasis added).

   Because the Supreme Court has not, as the majority opinion maintains, narrowly defined the term

“deceptive” to capture only direct misrepresentations or omissions, this court must construe the

disputed statutory language “not technically and restrictively, but flexibly to effectuate its remedial

purposes.” SEC v. Zandford, 535 U.S. 813, 819 (2002) (internal quotation marks omitted). In light


                                                  30
of this canon of interpretation, I see no basis for the majority opinion’s strict, narrow reading, and

I agree with the district court, the Ninth Circuit, Judge Kaplan, and the SEC that Section 10(b)’s

prohibition on directly or indirectly employing any “deceptive device or contrivance” can reach

secondary actors who, with scienter, engage in fraudulent transactions that are used to inflate an

issuer’s financial results. See Simpson, 452 F.3d at 1050 (“If a defendant’s conduct or role in an

illegitimate transaction has the principal purpose and effect of creating a false appearance of fact in

the furtherance of a scheme to defraud, then the defendant is using or employing a deceptive device

within the meaning of § 10(b).”); Enron, 2006 U.S. Dist. LEXIS 43146, at *167-74 (adopting SEC

view “that a deceptive act includes a transaction whose principal purpose and effect is to create a false

appearance of revenues, which can be accomplished by acts as well as by words”) (internal quotation

marks omitted); Parmalat, 376 F. Supp. 2d at 502-03.12

                                                    III.

   The investment banks also assert that the district court erred by failing to apply this court’s

decision in Greenberg v. Crossroad Systems, Inc., 364 F.3d 657 (5th Cir. 2004), to determine

whether the plaintiffs could proceed under the fraud-on-the-market theory. In Greenberg, a panel

of this court held that plaintiffs who seek to invoke the fraud-on-the-market presumption of reliance

must show both that the misrepresentations made to the market were “non-confirmatory,” i.e., that

they did not simply confirm the market’s expectations, and that the misrepresentations actually




   12
     Although those courts that have found that Section 10(b) can reach conduct of the type alleged here have
developed different formulations of the standard for liability, see Simpson, 452 F.3d at 1048 & n.5, I agree
with the majority that any such distinctions are not relevant to this interlocutory appeal. See supra, at ___
n.25.

                                                    31
affected the market price of the securities in question. See id. at 665-66.13

   In its June 5, 2006 opinion, the district court declined to apply Greenberg to this case. The district

court concluded that Greenberg applies only to cases under Rule 10b-5(b) involving misrepresenta-

tions, not to cases like this one involving a scheme to defraud under Rule 10b-5(a) or (c). See Enron,

2006 U.S. Dist. LEXIS 43146, at *287-88. On appeal, the plaintiffs proffer several additional

reasons why Greenberg does not mandate reversal. Plaintiffs assert that (1) Greenberg does not apply

to cases like this one, where the alleged scheme to defraud stems from the defendants’ fraudulent

efforts to conceal from the market information that would show that the issuer is not actually meeting

the market’s expectations; (2) Greenberg should not be read to saddle plaintiffs with the burden of

showing that the alleged misrepresentations actually changed the market price of the issuer’s

securities; and (3) Greenberg’s requirements have, in any event, been satisfied in this case.

   I agree with the plaintiffs that this court cannot use Greenberg to relieve the defendants of the

burden, allocated to them in Basic and in subsequent decisions of this court, of rebutting the fraud-on-

the-market presumption. In Basic itself, the Supreme Court was unmistakably clear that the

defendant has the burden of rebutting the presumption of reliance:

        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,
        will be sufficient to rebut the presumption of reliance. For example, if [defendants]
        could show that the “market makers” were privy to the truth about the merger
        discussions here with Combustion, and thus that the market price would not have
        been affected by their misrepresentations, the causal connection could be broken: the
        basis for finding that the fraud had been transmitted through market price would be
        gone.


   13
      This required showing is in addition to Basic’s requirements that plaintiffs show that (1) there were
material, public misrepresentations; (2) the securities in question traded in an efficient market; and (3) the
plaintiffs traded in the securities in question between the date of the misrepresentations and the date on which
the truth was disclosed to the market. See Greenberg, 364 F.3d at 661.

                                                      32
Basic, 485 U.S. at 248; see also id. at 245 (“Arising out of considerations of fairness, public policy,

and probability, as well as judicial economy, presumptions are also useful devices for allocating the

burdens of proof between parties.”). The clear import of Basic was not lost on this court. In Fine

v. American Solar King Corp., 919 F.2d 290, 299 (5th Cir. 1990), this court recognized that the

defendant could rebut Basic’s presumption of reliance only by showing: “(1) that the nondisclosures

did not affect the market price, or (2) that the Plaintiffs would have purchased the stock at the same

price had they known the information that was not disclosed; or (3) that the Plaintiffs actually knew

the information that was not disclosed to the market.”

   This court’s more recent decisions, including Greenberg, have at least professed fidelity to Basic’s

burden-shifting approach. In Greenberg, the court described the fraud-on-the-market presumption

as follows:

       Under this theory, reliance on the statement is rebuttably presumed if the plaintiffs can
       show that (1) the defendant made public material misrepresentations, (2) the
       defendant’s shares were traded in an efficient market, and (3) the plaintiffs traded
       shares between the time the misrepresentations were made and the time the truth was
       revealed. The Defendants may rebut this presumption by “[a]ny 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 fair market price[.]”

Greenberg, 364 F.3d at 661-62 (quoting Basic, 485 U.S. at 247) (alterations in original) (internal

citations and footnote omitted). In parts IV and V of its opinion, however, the Greenberg panel

changed course and found that it is actually the plaintiffs’ affirmative burden to show, as a

prerequisite to the application of the presumption, that the defendant’s misrepresentation actually

moved the market price of the security in question:

       We are satisfied that plaintiffs cannot trigger the presumption of reliance by simply
       offering evidence of any decrease in price following the release of negative
       information. Such evidence does not raise an inference that the stock's price was
       actually affected by an earlier release of positive information. To raise an inference

                                                 33
        through a decline in stock price that an earlier false, positive statement actually
        affected a stock's price, the plaintiffs must show that the false statement causing the
        increase was related to the statement causing the decrease.

Id. at 665; see also id. at 663 (referring to the plaintiffs’ “burden in a fraud-on-the-market case to

show that a stock’s price was actually affected by an allegedly false statement”).

   Greenberg appears to have mistakenly relied on this court’s earlier decision in Nathenson v.

Zonagen Inc., 267 F.3d 400 (5th Cir. 2001), as the authority for its decision to relieve securities

defendants of the burden of rebutting the fraud-on-the-market presumption. In Nathenson, a panel

of this court held that “where the facts properly considered by the district court reflect that the

information in question did not affect the price of the stock then the district court may properly deny

fraud-on-the-market based recovery.” Nathenson, 267 F.3d at 415. Nathenson did not, however,

expressly purport to convert the defendant’s burden of rebutting the fraud-on-the-market presumption

— by, for example, showing that the alleged misrepresentation had no effect on the market price of

the security — into a burden on the plaintiff to show that the misrepresentation did affect the price

of the security. Rather, the panel in Nathenson simply determined that a district court did not err

when it found that the allegations of the plaintiffs’ complaint affirmatively demonstrated that the

misrepresentations in question did not affect the price of the issuer’s stock. Id. at 414, 417-18. In

other words, the plaintiffs in Nathenson affirmatively pleaded themselves out of the fraud-on-the-

market presumption. Thus, Nathenson lends no support to the view that securities plaintiffs can

invoke the fraud-on-the-market presumption only if they first affirmatively demonstrate that the

market moved in response to the alleged misrepresentation.

   Because the Greenberg panel’s decision to reallocate the burdens in fraud-on-the-market cases

conflicts not only with Basic, but also with earlier decisions of this court, such as Fine, I would follow


                                                   34
those decisions and hold that the defendant retains the burden of rebutting Basic’s presumption of

reliance. See, e.g., Modica v. Taylor, 465 F.3d 174, 183 (5th Cir. 2006) (“‘When panel opinions

appear to conflict, we are bound to follow the earlier opinion.’”) (quoting H&D Tire & Auto.-

Hardware, Inc. v. Pitney Bowes Inc., 227 F.3d 326, 330 (5th Cir. 2001)); cf. Unger, 401 F.3d at 322

n.4 (“[I]t is the Supreme Court’s job to overrule Basic, in the absence of outright conflict with the

Private Securities Litigation Reform Act.”) (citation omitted). The banks do not appear to have

satisfied that burden on the record before us.14

                                                      IV.

   The banks argue that the district court erroneously determined that any defendant found to have

knowingly violated the securities laws could be held jointly and severally liable for all of the losses


   14
      Greenberg also purports to require that the plaintiffs establish that the defendant’s false statement was
“non-confirmatory” — i.e., that it did not simply confirm the market’s preexisting expectations about, for
example, the size of the issuer’s quarterly earnings — before the fraud-on-the-market presumption can apply.
See Greenberg, 364 F.3d at 665-66. According to the Greenberg panel, the market cannot rely on allegedly
false “confirmatory” statements because “confirmatory information has already been digested by the market
and will not cause a change in the stock price.” Id.; see also id. at 666 (“Because the presumption of reliance
is based upon actual movement of the stock price, confirmatory information cannot be the basis for a fraud-on-
the-market claim.”).
    This requirement from Greenberg appears to be based on a misinterpretation of this court’s earlier decision
in Nathenson. The Nathenson panel stated that, in certain “special circumstances,” such as when an issuer
provides false information that confirms the market’s expectations, the market can rely on those false
statements, even though the market price may not change at the time of the false “confirmatory” statement.
See Nathenson, 267 F.3d at 319. Rather, the statement’s effect on the market price will show only when the
falsity of the statement is later disclosed and the market price declines. See id.
    This makes sense: if the market expects earnings of $1.00 per share, then the share price might not move
in response to a false public statement confirming that the issuer earned $1.00 per share (even though the issuer
in fact lost $.50 per share). The lack of movement does not, however, mean that the false statement had no
actual effect on the share price. Had the issuer truthfully disclosed its loss of $.50 per share to a market that
expected earnings of $1.00 per share, the share price would have declined, rather than remaining steady; the
false “confirmatory” statement actually affected the share price by keeping it artificially high in a situation
where a truthful statement would have caused the share price to decline. As the Nathenson court suggested,
the effect that the false statement had on the share price in such a case can be shown when the falsity of the
statement is disclosed and the share price declines. See id.
    Thus, there appears to be no basis in Nathenson or otherwise for Greenberg’s conclusion that false
“confirmatory” statements can never support a claim proceeding under a fraud-on-the-market theory.

caused by Enron’s entire overarching fraudulent scheme. The banks assert that without this

erroneous legal conclusion, the district court could not have found that the proposed class satisfied

Rule 23(b)(3)’s predominance requirement or the manageability aspect of Rule 23(b)(3)’s superiority

requirement.15

   Before the enactment of the PSLRA, the general rule in Section 10(b) actions was that defendants

found to have violated Section 10(b) or Rule 10b-5 were jointly and severally liable for all of the

plaintiff’s damages. See, e.g., Musik, Peeler & Garrett v. Employers Ins. of Wausau, 508 U.S. 286,

292 (1993) (noting that violators “share joint liability for that wrong under a remedial scheme

established by the federal courts”); TBG, Inc. v. Bendis, 36 F.3d 916, 927 (10th Cir. 1994); G.A.

Thompson & Co. v. Partridge, 636 F.2d 945, 963 (5th Cir. 1981); Ross v. Licht, 263 F. Supp. 395,

411 (S.D.N.Y. 1967).16 The legislative history of the PSLRA suggests that Congress was concerned

about the unfairness that could result from the application of the traditional joint and several liability

rule in many cases. See H.R. Rep. No. 104-369, at 37 (1995) (Conf. Rep.), 1995 U.S.C.C.A.N. 730,

plaintiff. Thus, a defendant found responsible for only 1% of the harm could be required to pay 100%

of the damages.”). To combat this perceived unfairness, as part of the PSLRA, Congress enacted 15

U.S.C. § 78u-4(f), which replaced the existing joint and several liability regime with one of

proportionate liability and limited joint and several liability to defendants who knowingly violate the

securities laws. 15 U.S.C. § 78u-4(f)(2)(A) provides that any defendant “against whom a final

judgment is entered in a private action shall be liable for damages jointly and severally only if the trier

of fact specifically determines that such covered person knowingly committed a violation of the

securities laws.” If no knowing violation is found, the statute provides that the defendant “shall be

liable solely for the portion of the judgment that corresponds to the percentage of responsibility of

that [defendant].” Id. § 78u-4(f)(2)(B).

   The banks assert that, under these statutory provisions, a defendant who knowingly violates

Section 10(b) can be jointly and severally liable only for the damages caused by conduct in which that

defendant knowingly participated. Anything more, the banks argue, would run afoul of the PSLRA’s

requirement that the plaintiff must “prov[e] that the act or omission of the defendant alleged to violate

this chapter caused the loss for which the plaintiff seeks to recover damages,” id. § 78u-4(b)(4), and

would be tantamount to imposing liability for conspiracy to violate Section 10(b). See Dinsmore v.

Squadron, Ellenoff, Plesent, Sheinfeld & Sorkin, 135 F.3d 837, 841 (2d Cir. 1998) (stating that, post-

Central Bank, there is no cause of action for conspiracy to violate Section 10(b)). As the banks

would have it, then, even if they were found to have knowingly violated Section 10(b), they could

be held jointly and severally liable for only those damages that the plaintiffs suffered specifically as


                                                   37
a result of the transactions in which the banks participated with Enron. The plaintiffs, on the other

hand, assert that because the alleged conduct of the banks, Enron, and others was all part of a single

fraudulent scheme, any knowing violator can be held jointly and severally liable for harm caused by

the other scheme participants.

   In considering whether the proposed class satisfied the requirements of Rule 23(b)(3), the district

court rejected the banks’ argument and determined that the PSLRA permits courts to broadly impose

on knowing violators joint and several liability for all of the damages caused by a fraudulent scheme

as a whole:

        The Court finds that a reasonable argument can be made that where a defendant
        knowingly engaged in a primary violation of the federal securities law that was in
        furtherance of a larger scheme, it should be jointly and severally liable for the loss
        caused by the entire overarching scheme, including conduct of other scheme
        participants about which it knew nothing. Indeed, express joint and several liability
        in the statute is a meaningless concept if it is limited to a defendant’s own wrongdo-
        ing. This Court acknowledges that it has previously questioned whether liability for
        conduct caused by all the scheme participants is compatible with the “knowing”
        requirement under § 78u-4(f)(2)(A). Nevertheless, the Court observes that the
        PSLRA not only replaced joint and several liability with proportionate liability except
        when the conduct was “knowing”, but established a right to contribution under §
        78u-4(f)(8) to provide a remedy for unfairness, and, with a similar result, the
        judgment reduction formula embodied in § 78u-4(f)(2)(A) [sic]. Accordingly this
        Court concludes that Lead Plaintiff may pursue its claims for joint and several liability
        against those Defendants found to be primary violators in the scheme, as a whole.

   The text of the PSLRA’s joint and several liability provision does not, on its own, resolve this

issue. Section 78u-4(f)(2)(A) does not purport to define the scope of joint and several liability;

rather, that provision simply places limits on who can be subject to joint and several liability. The



   17
    The district court also correctly noted that there is a paucity of authority addressing this issue. See Enron,
2006 U.S. Dist. LEXIS 43146, at *222.

statute’s legislative history, however, indicates that Congress intended that the potential scope of joint

and several liability would remain the same as it was under the pre-PSLRA law. See H.R. Rep. No.

104-369, at 38, 1995 U.S.C.C.A.N. at 737 (“The Conference Report imposes full joint and several

liability, as under current law, on defendants who engage in knowing violations of the securities

laws.”); S. Rep. No. 104-98, at 22, 1995 U.S.C.C.A.N. at 701 (same).

   Under the pre-PSLRA practice described above, any defendant found to have violated Section

10(b) or Rule 10b-5 was jointly and severally liable for all of the damages suffered by the plaintiff;

no distinction was made based on what portion of the plaintiff’s damages were caused by, or traceable

to, any specific defendant’s conduct. See TBG, Inc., 36 F.3d at 927 (“Liability in Rule 10b-5 cases

is strictly joint and several and is never allocated among individual defendants in deciding the

plaintiff’s claim.”); Ross, 263 F. Supp. at 411 (finding joint and several liability for Section 10(b)

claim because “the participation of each defendant was essential to the success of the scheme and

there is no way to apportion guilt”); see also 5 Alan R. Bromberg & Lewis D. Lowenfels, Bromberg

& Lowenfels on Securities Fraud and Commodities Fraud § 8.48 (2d ed.) (“[A]ny person found to

have any liability whatsoever, no matter how insignificant, could be liable to plaintiffs for the total

damages caused by all the misconduct.”). Accordingly, there appears to be no support for the banks’

assertion that any joint and several liability must be limited to joint and several liability for only the

damages caused directly by the specific transactions in which they participated with Enron.

Therefore, if the plaintiffs could succeed in proving at trial that the conduct alleged amounted to a

single, overarching fraudulent scheme (as opposed to, as the banks assert, a number of separate and

distinct fraudulent schemes), they should be permitted to recover damages jointly and severally from

any knowing violator, and the scope of that joint and several liability should not be limited to the


                                                   39
damages caused directly by that defendant’s participation in the scheme.18

   The banks are correct, however, that the scope of joint and several liability for a knowing violation

of Section 10(b) must be informed by the reach of Section 10(b) itself. In particular, it seems

fundamental that a defendant cannot be jointly and severally liable to a plaintiff unless that defendant

is, in fact, primarily liable to that plaintiff. In other words, assuming that a jury finds that the banks

knowingly violated Section 10(b) through their alleged participation with Enron in a scheme to

defraud Enron’s investors, they can be held jointly and severally liable for all of the scheme-related

losses suffered by any investor who was harmed in some way by their conduct, but the banks cannot

be held responsible for the losses of any investors to whom they are not primarily liable under Section

10(b).

   In a multi-defendant securities class action such as this one, where presumably thousands of

investors were harmed by a number of different acts committed by different defendants over a period

of several years, not every plaintiff will have been harmed by every defendant. For example, if a

particular defendant, who was previously uninvolved with the scheme, first structured or participated

in a fraudulent transaction to falsely inflate Enron’s financial results near the end of the class period,

that defendant could not be held liable under Section 10(b) to any investors who purchased Enron

stock (the price of which may have already been inflated by the fraudulent acts of other defendants)

before that transaction. Since those investors purchased their stock before the defendant engaged

in any fraudulent conduct, they could not state a Section 10(b) claim against it, because they would


   18
     This court does not need to decide whether any defendant could be jointly and severally liable
for damages caused by the actions of others if the plaintiffs could not prove that all of the conduct
they allege was part of a single fraudulent scheme. In their brief, the plaintiffs concede that a
defendant can be jointly and severally liable only for the damages caused by a scheme in which it
participates.

                                                   40
be unable to show either that the defendant’s conduct caused them to purchase Enron stock at an

inflated price (the element of reliance, or transaction causation) or that it caused them any harm (the

element of loss causation). To make the defendant jointly and severally liable for the damages of

those investors would, therefore, effectively expand the defendant’s underlying Section 10(b) liability

to encompass plaintiffs who could not otherwise state a claim against it.19 It would simply be

inconsistent with the elements of a Section 10(b) claim to hold a knowing violator jointly and

severally liable for the damages of any plaintiff to whom it is not primarily liable under Section

10(b).20

   That the fraud in this case is alleged to have been the result of a single, overarching scheme to

defraud does not alter this conclusion. After Central Bank, a defendant can be liable under Section

10(b) only if it commits a primary violation of the statute. See Central Bank, 511 U.S. at 191. Under

the district court’s open-ended interpretation of the PSLRA’s joint and several liability provision,

however, a defendant’s knowing violation of the securities laws could not only increase the damages

for which it can be liable, but could also make that defendant responsible for the damages of plaintiffs

who were harmed exclusively by the conduct of others, and to whom that defendant could not

otherwise be liable at all. This, in my view, exceeds the permissible bounds of primary liability under

Section 10(b) and amounts to the impermissible imposition of conspiracy liability. See Dinsmore, 135

F.3d at 841.

   Because the district court’s class certification decision was based, in part, on this legal error, I

   19
    The plaintiffs expressly concede this point in their briefs, as they state that no defendant can be liable for
damages from before the date on which it violated Section 10(b).
   20
     In the example given, if the defendant knowingly violated Section 10(b), it could be jointly and severally
liable to any investors who purchased Enron stock after its fraudulent conduct and before the disclosure of the
truth, even if those investors were also harmed by the conduct of other participants in the scheme.

                                                       41
would reverse the decision to certify the class on this ground only and remand the case to the district

court to consider whether, in light of the proper interpretation of the PSLRA’s joint and several

liability provision, the proposed class still satisfies the predominance and superiority requirements of

Rule 23(b)(3).

                                          CONCLUSION

   Consequently, I concur in the judgment reversing the district court’s certification order, but I do

so only for the reasons assigned herein. I would remand the case to that court for additional

consideration of whether, in light of this opinion, this case meets Rule 23’s requirements for class

certification.
