The misappropriation theory allows for liability under §10(b) of the Securities Exchange Act for securities fraud based on the deceptive use of confidential information.
In United States v. O'Hagan, the Supreme Court clarified the scope of securities fraud under the 'misappropriation theory.' The case is significant because it upheld the notion that a person can be held liable for securities fraud not just when they trade on the basis of material nonpublic information that belongs to their employer, but also when they misappropriate information obtained from any source, including a law firm representing an entity involved in a business transaction. This case emphasized the importance of trust and confidentiality in the securities market, showing how breaches of that trust can lead to severe legal consequences.
Additionally, the ruling established that to be guilty of securities fraud, the deceiving party must have engaged in a fraudulent scheme to exploit confidential information for personal gain. O'Hagan's actions of purchasing stock and call options after receiving confidential information were viewed as a clear violation of the fiduciary duty owed to the source of that information, reinforcing the court's commitment to maintaining integrity in securities transactions.

| Case | Distinction |
|---|---|
| Chiarella v. United States | Chiarella focused on the necessity of a duty to disclose information to be liable for insider trading, whereas O'Hagan broadened the scope by allowing liability for misappropriating nonpublic information without a direct relationship to the source. |
| Dirks v. SEC | Dirks dealt with a tipper/Tippee liability framework in insider trading cases, while O'Hagan's case emphasizes the misappropriation of confidential information irrespective of whether the information was obtained directly from the source. |
| Securities and Exchange Commission v. Texas Gulf Sulphur Co. | Texas Gulf Sulphur involved corporate insider trading linked to public statements, while O'Hagan involved misappropriation of information gained through a professional relationship. |
The misappropriation theory encourages greater transparency and ethical conduct in the securities market by punishing those who exploit confidential information for personal gain.
Critics argue that the misappropriation theory can lead to overreach, penalizing individuals merely for using information obtained in the normal course of business without a clear indication of deceit or fraud.
This case frequently appears on exams as a key illustration of the misappropriation theory in securities law, often explored in relation to fiduciary duties and deceptive practices.
