Whether a person violates § 10(b) and Rule 10b-5 by trading on material, nonpublic information misappropriated from the information's source in breach of a duty of trust and confidence.
Holding
Yes. The misappropriation theory supports criminal liability under § 10(b) and Rule 10b-5 when a fiduciary or similar confidant secretly uses entrusted confidential information for securities trading.
Reasoning
Section 10(b) prohibits the use of a manipulative or deceptive device “in connection with” the purchase or sale of securities. It does not require that the deception be practiced on the person on the other side of the securities transaction. A fiduciary who pretends loyalty while secretly converting the principal's confidential information for personal trading profit deceives the source of the information.
The theory differs from the classical insider-trading theory, but complements it. Classical liability rests on an insider's duty to the corporation's shareholders; misappropriation liability rests on an outsider's breach of a duty owed to the source of confidential information. By barring that deceptive use of information, the theory protects market integrity against trading by outsiders who possess confidential market-moving information but owe no duty to the target company's shareholders.
The required connection to a securities transaction exists because the fraud is completed when the fiduciary, without disclosing his plan to the information source, uses the confidential information to trade. The secret breach of duty and the securities transaction therefore coincide. If the fiduciary fully discloses the intended trading to the source, the deceptive element is absent, though state-law duties may still be implicated.
Chiarella did not foreclose the theory; it rejected only a general duty for all market participants to disclose material nonpublic information and expressly left the misappropriation question unresolved. Dirks likewise did not help O'Hagan because the analyst there neither misappropriated information nor received it subject to an expectation of confidentiality. Central Bank concerned private aiding-and-abetting liability, not the scope of criminal primary liability under § 10(b).
The Court also emphasized statutory safeguards against unfair criminal punishment. The Government must prove that the defendant willfully violated the securities law, and a defendant cannot be imprisoned for violating an SEC rule if he proves he did not know of the rule.
