Justice Ginsburg, delivered the opinion of the Court.
This case concerns the interpretation and enforcement of § 10(b) and § 14(e) of the Securities Exchange Act of 1934, and rules made by the Securities and Exchange Commission pursuant to these provisions, Rule 10b5 and Rule 14e3(a). *647 Two prime questions are presented. The first relates to the misappropriation of material, nonpublic information for securities trading; the second concerns fraudulent practices in the tender offer setting. In particular, we address and resolve these issues: (1) Is a person who trades in securities for personal profit, using confidential information misappropriated in breach of a fiduciary duty to the source of the information, guilty of violating § 10(b) and Rule 10b5? (2) Did the Commission exceed its rulemaking authority by adopting Rule 14e3(a), which proscribes trading on undisclosed information in the tender offer setting, even in the absence of a duty to disclose? Our answer to the first question is yes, and to the second question, viewed in the context of this case, no.
I
Respondent James Herman O'Hagan was a partner in the law firm of Dorsey & Whitney in Minneapolis, Minnesota. In July 1988, Grand Metropolitan PLC (Grand Met), a company based in London, England, retained Dorsey & Whitney as local counsel to represent Grand Met regarding a potential tender offer for the common stock of the Pillsbury Company, headquartered in Minneapolis. Both Grand Met and Dorsey & Whitney took precautions to protect the confidentiality of Grand Met's tender offer plans. O'Hagan did no work on the Grand Met representation. Dorsey & Whitney withdrew from representing Grand Met on September 9, 1988. Less than a month later, on October 4, 1988, Grand Met publicly announced its tender offer for Pillsbury stock.
On August 18, 1988, while Dorsey & Whitney was still representing Grand Met, O'Hagan began purchasing call options for Pillsbury stock. Each option gave him the right to purchase 100 shares of Pillsbury stock by a specified date in September 1988. Later in August and in September, O'Hagan made additional purchases of Pillsbury call options. By the end of September, he owned 2,500 unexpired Pillsbury options, apparently more than any other individual investor. *648 See App. 85, 148. O'Hagan also purchased, in September 1988, some 5,000 shares of Pillsbury common stock, at a price just under $39 per share. When Grand Met announced its tender offer in October, the price of Pillsbury stock rose to nearly $60 per share. O'Hagan then sold his Pillsbury call options and common stock, making a profit of more than $4.3 million.
The Securities and Exchange Commission (SEC or Commission) initiated an investigation into O'Hagan's transactions, culminating in a 57-count indictment. The indictment alleged that O'Hagan defrauded his law firm and its client, Grand Met, by using for his own trading purposes material, nonpublic information regarding Grand Met's planned tender offer. Id., at 8.[1] According to the indictment, O'Hagan used the profits he gained through this trading to conceal his previous embezzlement and conversion of unrelated client trust funds. Id., at 10.[2] O'Hagan was charged with 20 counts of mail fraud, in violation of 18 U. S. C. § 1341; 17 counts of securities fraud, in violation of § 10(b) of the Securities Exchange Act of 1934 (Exchange Act), 48 Stat. 891, 15 U. S. C. § 78j(b), and SEC Rule 10b5, 17 CFR § 240.10b5 *649 (1996); 17 counts of fraudulent trading in connection with a tender offer, in violation of § 14(e) of the Exchange Act, 15 U. S. C. § 78n(e), and SEC Rule 14e3(a), 17 CFR § 240.14e 3(a) (1996); and 3 counts of violating federal money laundering statutes, 18 U. S. C. §§ 1956(a)(1)(B)(i), 1957. See App. 13-24. A jury convicted O'Hagan on all 57 counts, and he was sentenced to a 41-month term of imprisonment.
A divided panel of the Court of Appeals for the Eighth Circuit reversed all of O'Hagan's convictions. 92 F. 3d 612 (1996). Liability under § 10(b) and Rule 10b5, the Eighth Circuit held, may not be grounded on the "misappropriation theory" of securities fraud on which the prosecution relied. Id., at 622. The Court of Appeals also held that Rule 14e 3(a)which prohibits trading while in possession of material, nonpublic information relating to a tender offerexceeds the SEC's § 14(e) rulemaking authority because the Rule contains no breach of fiduciary duty requirement. Id., at 627. The Eighth Circuit further concluded that O'Hagan's mail fraud and money laundering convictions rested on violations of the securities laws, and therefore could not stand once the securities fraud convictions were reversed. Id., at 627-628. Judge Fagg, dissenting, stated that he would recognize and enforce the misappropriation theory, and would hold that the SEC did not exceed its rulemaking authority when it adopted Rule 14e3(a) without requiring proof of a breach of fiduciary duty. Id., at 628.
Decisions of the Courts of Appeals are in conflict on the propriety of the misappropriation theory under § 10(b) and Rule 10b5, see infra this page and 650, and n. 3, and on the legitimacy of Rule 14e3(a) under § 14(e), see infra, at 669 670. We granted certiorari, 519 U. S. 1087 (1997), and now reverse the Eighth Circuit's judgment.
II
We address first the Court of Appeals' reversal of O'Hagan's convictions under § 10(b) and Rule 10b5. Following *650 the Fourth Circuit's lead, see United States v. Bryan, 58 F. 3d 933, 943-959 (1995), the Eighth Circuit rejected the misappropriation theory as a basis for § 10(b) liability. We hold, in accord with several other Courts of Appeals,[3] that criminal liability under § 10(b) may be predicated on the misappropriation theory.[4]
A
In pertinent part, § 10(b) of the Exchange Act provides:
"It shall be unlawful for any person, directly or indirectly, by the use of any means or instrumentality of interstate commerce or of the mails, or of any facility of any national securities exchange
. . . . .
"(b) To use or employ, in connection with the purchase or sale of any security registered on a national securities exchange or any security not so registered, any manipulative or deceptive device or contrivance in contravention of such rules and regulations as the [Securities and Exchange] Commission may prescribe as necessary or appropriate in the public interest or for the protection of investors." 15 U. S. C. § 78j(b). *651 The statute thus proscribes (1) using any deceptive device (2) in connection with the purchase or sale of securities, in contravention of rules prescribed by the Commission. The provision, as written, does not confine its coverage to deception of a purchaser or seller of securities, see United States v. Newman, 664 F. 2d 12, 17 (CA2 1981); rather, the statute reaches any deceptive device used "in connection with the purchase or sale of any security."
Pursuant to its § 10(b) rulemaking authority, the Commission has adopted Rule 10b5, which, as relevant here, provides:
"It shall be unlawful for any person, directly or indirectly, by the use of any means or instrumentality of interstate commerce, or of the mails or of any facility of any national securities exchange,
"(a) To employ any device, scheme, or artifice to defraud, [or]
. . . . .
"(c) To engage in any act, practice, or course of business which operates or would operate as a fraud or deceit upon any person, "in connection with the purchase or sale of any security." 17 CFR § 240.10b5 (1996).
Liability under Rule 10b5, our precedent indicates, does not extend beyond conduct encompassed by § 10(b)'s prohibition. See Ernst & Ernst v. Hochfelder, 425 U. S. 185, 214 (1976) (scope of Rule 10b5 cannot exceed power Congress granted Commission under § 10(b)); see also Central Bank of Denver, N. A. v. First Interstate Bank of Denver, N. A., 511 U. S. 164, 173 (1994) ("We have refused to allow [private] 10b5 challenges to conduct not prohibited by the text of the statute.").
Under the "traditional" or "classical theory" of insider trading liability, § 10(b) and Rule 10b5 are violated when a corporate insider trades in the securities of his corporation *652 on the basis of material, nonpublic information. Trading on such information qualifies as a "deceptive device" under § 10(b), we have affirmed, because "a relationship of trust and confidence [exists] between the shareholders of a corporation and those insiders who have obtained confidential information by reason of their position with that corporation." Chiarella v. United States, 445 U. S. 222, 228 (1980). That relationship, we recognized, "gives rise to a duty to disclose [or to abstain from trading] because of the `necessity of preventing a corporate insider from . . . tak[ing] unfair advantage of . . . uninformed . . . stockholders.' " Id., at 228-229 (citation omitted). The classical theory applies not only to officers, directors, and other permanent insiders of a corporation, but also to attorneys, accountants, consultants, and others who temporarily become fiduciaries of a corporation. See Dirks v. SEC, 463 U. S. 646, 655, n. 14 (1983).
The "misappropriation theory" holds that a person commits fraud "in connection with" a securities transaction, and thereby violates § 10(b) and Rule 10b5, when he misappropriates confidential information for securities trading purposes, in breach of a duty owed to the source of the information. See Brief for United States 14. Under this theory, a fiduciary's undisclosed, self-serving use of a principal's information to purchase or sell securities, in breach of a duty of loyalty and confidentiality, defrauds the principal of the exclusive use of that information. In lieu of premising liability on a fiduciary relationship between company insider and purchaser or seller of the company's stock, the misappropriation theory premises liability on a fiduciary-turned-trader's deception of those who entrusted him with access to confidential information.
The two theories are complementary, each addressing efforts to capitalize on nonpublic information through the purchase or sale of securities. The classical theory targets a corporate insider's breach of duty to shareholders with whom the insider transacts; the misappropriation theory outlaws *653 trading on the basis of nonpublic information by a corporate "outsider" in breach of a duty owed not to a trading party, but to the source of the information. The misappropriation theory is thus designed to "protec[t] the integrity of the securities markets against abuses by `outsiders' to a corporation who have access to confidential information that will affect th[e] corporation's security price when revealed, but who owe no fiduciary or other duty to that corporation's shareholders." Ibid.
In this case, the indictment alleged that O'Hagan, in breach of a duty of trust and confidence he owed to his law firm, Dorsey & Whitney, and to its client, Grand Met, traded on the basis of nonpublic information regarding Grand Met's planned tender offer for Pillsbury common stock. App. 16. This conduct, the Government charged, constituted a fraudulent device in connection with the purchase and sale of securities.[5]
B
We agree with the Government that misappropriation, as just defined, satisfies § 10(b)'s requirement that chargeable conduct involve a "deceptive device or contrivance" used "in connection with" the purchase or sale of securities. We observe, first, that misappropriators, as the Government describes them, deal in deception. A fiduciary who "[pretends] loyalty to the principal while secretly converting the principal's information for personal gain," Brief for United States *654 17, "dupes" or defrauds the principal. See Aldave, Misappropriation: A General Theory of Liability for Trading on Nonpublic Information, 13 Hofstra L. Rev. 101, 119 (1984).
We addressed fraud of the same species in Carpenter v. United States, 484 U. S. 19 (1987), which involved the mail fraud statute's proscription of "any scheme or artifice to defraud," 18 U. S. C. § 1341. Affirming convictions under that statute, we said in Carpenter that an employee's undertaking not to reveal his employer's confidential information "became a sham" when the employee provided the information to his co-conspirators in a scheme to obtain trading profits. 484 U. S., at 27. A company's confidential information, we recognized in Carpenter, qualifies as property to which the company has a right of exclusive use. Id., at 25-27. The undisclosed misappropriation of such information, in violation of a fiduciary duty, the Court said in Carpenter, constitutes fraud akin to embezzlement"`the fraudulent appropriation to one's own use of the money or goods entrusted to one's care by another.' " Id., at 27 (quoting Grin v. Shine, 187 U. S. 181, 189 (1902)); see Aldave, 13 Hofstra L. Rev., at 119. Carpenter `s discussion of the fraudulent misuse of confidential information, the Government notes, "is a particularly apt source of guidance here, because [the mail fraud statute] (like Section 10(b)) has long been held to require deception, not merely the breach of a fiduciary duty." Brief for United States 18, n. 9 (citation omitted).
Deception through nondisclosure is central to the theory of liability for which the Government seeks recognition. As counsel for the Government stated in explanation of the theory at oral argument: "To satisfy the common law rule that a trustee may not use the property that [has] been entrusted [to] him, there would have to be consent. To satisfy the requirement of the Securities Act that there be no deception, there would only have to be disclosure." Tr. of Oral Arg. 12; see generally Restatement (Second) of Agency §§ 390, 395 *655 (1958) (agent's disclosure obligation regarding use of confidential information).[6]
The misappropriation theory advanced by the Government is consistent with Santa Fe Industries, Inc. v. Green, 430 U. S. 462 (1977), a decision underscoring that § 10(b) is not an all-purpose breach of fiduciary duty ban; rather, it trains on conduct involving manipulation or deception. See id., at 473-476. In contrast to the Government's allegations in this case, in Santa Fe Industries, all pertinent facts were disclosed by the persons charged with violating § 10(b) and Rule 10b5, see id., at 474; therefore, there was no deception through nondisclosure to which liability under those provisions could attach, see id., at 476. Similarly, full disclosure forecloses liability under the misappropriation theory: Because the deception essential to the misappropriation theory involves feigning fidelity to the source of information, if the fiduciary discloses to the source that he plans to trade on the nonpublic information, there is no "deceptive device" and thus no § 10(b) violationalthough the fiduciary-turnedtrader may remain liable under state law for breach of a duty of loyalty.[7]
We turn next to the § 10(b) requirement that the misappropriator's deceptive use of information be "in connection with *656 the purchase or sale of [a] security." This element is satisfied because the fiduciary's fraud is consummated, not when the fiduciary gains the confidential information, but when, without disclosure to his principal, he uses the information to purchase or sell securities. The securities transaction and the breach of duty thus coincide. This is so even though the person or entity defrauded is not the other party to the trade, but is, instead, the source of the nonpublic information. See Aldave, 13 Hofstra L. Rev., at 120 ("a fraud or deceit can be practiced on one person, with resultant harm to another person or group of persons"). A misappropriator who trades on the basis of material, nonpublic information, in short, gains his advantageous market position through deception; he deceives the source of the information and simultaneously harms members of the investing public. See id., at 120-121, and n. 107.
The misappropriation theory targets information of a sort that misappropriators ordinarily capitalize upon to gain norisk profits through the purchase or sale of securities. Should a misappropriator put such information to other use, the statute's prohibition would not be implicated. The theory does not catch all conceivable forms of fraud involving confidential information; rather, it catches fraudulent means of capitalizing on such information through securities transactions.
The Government notes another limitation on the forms of fraud § 10(b) reaches: "The misappropriation theory would not . . . apply to a case in which a person defrauded a bank into giving him a loan or embezzled cash from another, and then used the proceeds of the misdeed to purchase securities." Brief for United States 24, n. 13. In such a case, the Government states, "the proceeds would have value to the malefactor apart from their use in a securities transaction, and the fraud would be complete as soon as the money was obtained." Ibid. In other words, money can buy, if not anything, then at least many things; its misappropriation *657 may thus be viewed as sufficiently detached from a subsequent securities transaction that § 10(b)'s "in connection with" requirement would not be met. Ibid.
Justice Thomas' charge that the misappropriation theory is incoherent because information, like funds, can be put to multiple uses, see post, at 681-686 (opinion concurring in judgment in part and dissenting in part), misses the point. The Exchange Act was enacted in part "to insure the maintenance of fair and honest markets," 15 U. S. C. § 78b, and there is no question that fraudulent uses of confidential information fall within § 10(b)'s prohibition if the fraud is "in connection with" a securities transaction. It is hardly remarkable that a rule suitably applied to the fraudulent uses of certain kinds of information would be stretched beyond reason were it applied to the fraudulent use of money.
Justice Thomas does catch the Government in overstatement. Observing that money can be used for all manner of purposes and purchases, the Government urges that confidential information of the kind at issue derives its value only from its utility in securities trading. See Brief for United States 10, 21; post, at 683-684 (several times emphasizing the word "only"). Substitute "ordinarily" for "only," and the Government is on the mark.[8]
*658 Our recognition that the Government's "only" is an overstatement has provoked the dissent to cry "new theory." See post, at 687-689. But the very case on which Justice Thomas relies, Motor Vehicle Mfrs. Assn. of United States, Inc. v. State Farm Mut. Automobile Ins. Co., 463 U. S. 29 (1983), shows the extremity of that charge. In State Farm, we reviewed an agency's rescission of a rule under the same "arbitrary and capricious" standard by which the promulgation of a rule under the relevant statute was to be judged, see id., at 41-42; in our decision concluding that the agency had not adequately explained its regulatory action, see id., at 57, we cautioned that a "reviewing court should not attempt itself to make up for such deficiencies," id., at 43. Here, by contrast, Rule 10b5's promulgation has not been challenged; we consider only the Government's charge that O'Hagan's alleged fraudulent conduct falls within the prohibitions of the Rule and § 10(b). In this context, we acknowledge simply that, in defending the Government's interpretation of the Rule and statute in this Court, the Government's lawyers have pressed a solid point too far, something lawyers, occasionally even judges, are wont to do.
The misappropriation theory comports with § 10(b)'s language, which requires deception "in connection with the purchase or sale of any security," not deception of an identifiable purchaser or seller. The theory is also well tuned to an animating purpose of the Exchange Act: to insure honest securities markets and thereby promote investor confidence. See 45 Fed. Reg. 60412 (1980) (trading on misappropriated information "undermines the integrity of, and investor confidence in, the securities markets"). Although informational disparity is inevitable in the securities markets, investors likely would hesitate to venture their capital in a market where trading based on misappropriated nonpublic information is unchecked by law. An investor's informational disadvantage vis-à-vis a misappropriator with material, nonpublic information *659 stems from contrivance, not luck; it is a disadvantage that cannot be overcome with research or skill. See Brudney, Insiders, Outsiders, and Informational Advantages Under the Federal Securities Laws, 93 Harv. L. Rev. 322, 356 (1979) ("If the market is thought to be systematically populated with . . . transactors [trading on the basis of misappropriated information] some investors will refrain from dealing altogether, and others will incur costs to avoid dealing with such transactors or corruptly to overcome their unerodable informational advantages."); Aldave, 13 Hofstra L. Rev., at 122-123.
In sum, considering the inhibiting impact on market participation of trading on misappropriated information, and the congressional purposes underlying § 10(b), it makes scant sense to hold a lawyer like O'Hagan a § 10(b) violator if he works for a law firm representing the target of a tender offer, but not if he works for a law firm representing the bidder. The text of the statute requires no such result.[9] The misappropriation at issue here was properly made the subject of a § 10(b) charge because it meets the statutory requirement that there be "deceptive" conduct "in connection with" securities transactions.
*660 C
The Court of Appeals rejected the misappropriation theory primarily on two grounds. First, as the Eighth Circuit comprehended the theory, it requires neither misrepresentation nor nondisclosure. See 92 F. 3d, at 618. As we just explained, however, see supra, at 654-655, deceptive nondisclosure is essential to the § 10(b) liability at issue. Concretely, in this case, "it [was O'Hagan's] failure to disclose his personal trading to Grand Met and Dorsey, in breach of his duty to do so, that ma[de] his conduct `deceptive' within the meaning of [§ ]10(b)." Reply Brief 7.
Second and "more obvious," the Court of Appeals said, the misappropriation theory is not moored to § 10(b)'s requirement that "the fraud be `in connection with the purchase or sale of any security.' " 92 F. 3d, at 618 (quoting 15 U. S. C. § 78j(b)). According to the Eighth Circuit, three of our decisions reveal that § 10(b) liability cannot be predicated on a duty owed to the source of nonpublic information: Chiarella v. United States, 445 U. S. 222 (1980); Dirks v. SEC, 463 U. S. 646 (1983); and Central Bank of Denver, N. A. v. First Interstate Bank of Denver, N. A., 511 U. S. 164 (1994). "[O]nly a breach of a duty to parties to the securities transaction," the Court of Appeals concluded, "or, at the most, to other market participants such as investors, will be sufficient to give rise to § 10(b) liability." 92 F. 3d, at 618. We read the statute and our precedent differently, and note again that § 10(b) refers to "the purchase or sale of any security," not to identifiable purchasers or sellers of securities.
Chiarella involved securities trades by a printer employed at a shop that printed documents announcing corporate takeover bids. See 445 U. S., at 224. Deducing the names of target companies from documents he handled, the printer bought shares of the targets before takeover bids were announced, expecting (correctly) that the share prices would rise upon announcement. In these transactions, the printer did not disclose to the sellers of the securities (the target *661 companies' shareholders) the nonpublic information on which he traded. See ibid. For that trading, the printer was convicted of violating § 10(b) and Rule 10b5. We reversed the Court of Appeals judgment that had affirmed the conviction. See id., at 225.
The jury in Chiarella had been instructed that it could convict the defendant if he willfully failed to inform sellers of target company securities that he knew of a takeover bid that would increase the value of their shares. See id., at 226. Emphasizing that the printer had no agency or other fiduciary relationship with the sellers, we held that liability could not be imposed on so broad a theory. See id., at 235. There is under § 10(b), we explained, no "general duty between all participants in market transactions to forgo actions based on material, nonpublic information." Id., at 233. Under established doctrine, we said, a duty to disclose or abstain from trading "arises from a specific relationship between two parties." Ibid.
The Court did not hold in Chiarella that the only relationship prompting liability for trading on undisclosed information is the relationship between a corporation's insiders and shareholders. That is evident from our response to the Government's argument before this Court that the printer's misappropriation of information from his employer for purposes of securities tradingin violation of a duty of confidentiality owed to the acquiring companiesconstituted fraud in connection with the purchase or sale of a security, and thereby satisfied the terms of § 10(b). Id., at 235-236. The Court declined to reach that potential basis for the printer's liability, because the theory had not been submitted to the jury. See id., at 236-237. But four Justices found merit in it. See id., at 239 (Brennan, J., concurring in judgment); id., at 240-243 (Burger, C. J., dissenting); id., at 245 (Blackmun, J., joined by Marshall, J., dissenting). And a fifth Justice stated that the Court "wisely le[ft] the resolution of this issue for another day." Id., at 238 (Stevens, J., concurring).
*662 Chiarella thus expressly left open the misappropriation theory before us today. Certain statements in Chiarella, however, led the Eighth Circuit in the instant case to conclude that § 10(b) liability hinges exclusively on a breach of duty owed to a purchaser or seller of securities. See 92 F. 3d, at 618. The Court said in Chiarella that § 10(b) liability "is premised upon a duty to disclose arising from a relationship of trust and confidence between parties to a transaction, " 445 U. S., at 230 (emphasis added), and observed that the printshop employee defendant in that case "was not a person in whom the sellers had placed their trust and confidence," see id., at 232. These statements rejected the notion that § 10(b) stretches so far as to impose "a general duty between all participants in market transactions to forgo actions based on material, nonpublic information," id., at 233, and we confine them to that context. The statements highlighted by the Eighth Circuit, in short, appear in an opinion carefully leaving for future resolution the validity of the misappropriation theory, and therefore cannot be read to foreclose that theory.
Dirks, too, left room for application of the misappropriation theory in cases like the one we confront.[10]Dirks involved an investment analyst who had received information from a former insider of a corporation with which the analyst had no connection. See 463 U. S., at 648-649. The information indicated that the corporation had engaged in a massive fraud. The analyst investigated the fraud, obtaining corroborating information from employees of the corporation. During his investigation, the analyst discussed his findings with clients and investors, some of whom sold their holdings in the company the analyst suspected of gross wrongdoing. See id., at 649.
*663 The SEC censured the analyst for, inter alia, aiding and abetting § 10(b) and Rule 10b5 violations by clients and investors who sold their holdings based on the nonpublic information the analyst passed on. See id., at 650-652. In the SEC's view, the analyst, as a "tippee" of corporation insiders, had a duty under § 10(b) and Rule 10b5 to refrain from communicating the nonpublic information to persons likely to trade on the basis of it. See id., at 651, 655-656. This Court found no such obligation, see id., at 665-667, and repeated the key point made in Chiarella: There is no "`general duty between all participants in market transactions to forgo actions based on material, nonpublic information.' " 463 U. S., at 655 (quoting Chiarella, 445 U. S., at 233); see Aldave, 13 Hofstra L. Rev., at 122 (misappropriation theory bars only "trading on the basis of information that the wrongdoer converted to his own use in violation of some fiduciary, contractual, or similar obligation to the owner or rightful possessor of the information").
No showing had been made in Dirks that the "tippers" had violated any duty by disclosing to the analyst nonpublic information about their former employer. The insiders had acted not for personal profit, but to expose a massive fraud within the corporation. See 463 U. S., at 666-667. Absent any violation by the tippers, there could be no derivative liability for the tippee. See id., at 667. Most important for purposes of the instant case, the Court observed in Dirks: "There was no expectation by [the analyst's] sources that he would keep their information in confidence. Nor did [the analyst] misappropriate or illegally obtain the information . . . ." Id., at 665. Dirks thus presents no suggestion that a person who gains nonpublic information through misappropriation in breach of a fiduciary duty escapes § 10(b) liability when, without alerting the source, he trades on the information.
Last of the three cases the Eighth Circuit regarded as warranting disapproval of the misappropriation theory, Cen- *664 tral Bank held that "a private plaintiff may not maintain an aiding and abetting suit under § 10(b)." 511 U. S., at 191. We immediately cautioned in Central Bank that secondary actors in the securities markets may sometimes be chargeable under the securities Acts: "Any person or entity, including a lawyer, accountant, or bank, who employs a manipulative device or makes a material misstatement (or omission) on which a purchaser or seller of securities relies may be liable as a primary violator under 10b5, assuming . . . the requirements for primary liability under Rule 10b5 are met." Ibid. (emphasis added). The Eighth Circuit isolated the statement just quoted and drew from it the conclusion that § 10(b) covers only deceptive statements or omissions on which purchasers and sellers, and perhaps other market participants, rely. See 92 F. 3d, at 619. It is evident from the question presented in Central Bank, however, that this Court, in the quoted passage, sought only to clarify that secondary actors, although not subject to aiding and abetting liability, remain subject to primary liability under § 10(b) and Rule 10b5 for certain conduct.
Furthermore, Central Bank `s discussion concerned only private civil litigation under § 10(b) and Rule 10b5, not criminal liability. Central Bank `s reference to purchasers or sellers of securities must be read in light of a longstanding limitation on private § 10(b) suits. In Blue Chip Stamps v. Manor Drug Stores, 421 U. S. 723 (1975), we held that only actual purchasers or sellers of securities may maintain a private civil action under § 10(b) and Rule 10b5. We so confined the § 10(b) private right of action because of "policy considerations." Id., at 737. In particular, Blue Chip Stamps recognized the abuse potential and proof problems inherent in suits by investors who neither bought nor sold, but asserted they would have traded absent fraudulent conduct by others. See id., at 739-747; see also Holmes v. Securities Investor Protection Corporation, 503 U. S. 258, 285 *665 (1992) (O'Connor, J., concurring in part and concurring in judgment); id., at 289-290 (Scalia, J., concurring in judgment). Criminal prosecutions do not present the dangers the Court addressed in Blue Chip Stamps, so that decision is "inapplicable" to indictments for violations of § 10(b) and Rule 10b5. United States v. Naftalin, 441 U. S. 768, 774, n. 6 (1979); see also Holmes, 503 U. S., at 281 (O'Connor, J., concurring in part and concurring in judgment) ("[T]he purchaser/seller standing requirement for private civil actions under § 10(b) and Rule 10b5 is of no import in criminal prosecutions for willful violations of those provisions.").
In sum, the misappropriation theory, as we have examined and explained it in this opinion, is both consistent with the statute and with our precedent.[11] Vital to our decision that criminal liability may be sustained under the misappropriation theory, we emphasize, are two sturdy safeguards Congress has provided regarding scienter. To establish a criminal violation of Rule 10b5, the Government must prove that a person "willfully" violated the provision. See 15 U. S. C. *666 § 78ff(a).[12] Furthermore, a defendant may not be imprisoned for violating Rule 10b5 if he proves that he had no knowledge of the Rule. See ibid.[13] O'Hagan's charge that the misappropriation theory is too indefinite to permit the imposition of criminal liability, see Brief for Respondent 30 33, thus fails not only because the theory is limited to those who breach a recognized duty. In addition, the statute's "requirement of the presence of culpable intent as a necessary element of the offense does much to destroy any force in the argument that application of the [statute]" in circumstances such as O'Hagan's is unjust. Boyce Motor Lines, Inc. v. United States, 342 U. S. 337, 342 (1952).
The Eighth Circuit erred in holding that the misappropriation theory is inconsistent with § 10(b). The Court of Appeals may address on remand O'Hagan's other challenges to his convictions under § 10(b) and Rule 10b5.
III
We consider next the ground on which the Court of Appeals reversed O'Hagan's convictions for fraudulent trading in connection with a tender offer, in violation of § 14(e) of the Exchange Act and SEC Rule 14e3(a). A sole question is before us as to these convictions: Did the Commission, as the Court of Appeals held, exceed its rulemaking authority under § 14(e) when it adopted Rule 14e3(a) without requiring a showing that the trading at issue entailed a breach of *667 fiduciar
