Professor Coffee tackles the “shadow trading” theory

Here is a great article—no surprise considering its author, Columbia Law Professor John Coffee—that practically gives the last rites to the “shadow trading” theory recently accepted by a federal district court (see this PubCo post) and a jury (see this PubCo post) in SEC v. Panuwat.  If, that is, the theory ever reaches the Supreme Court. In Panuwat, the jury in a federal district court in California determined that Matthew Panuwat was civilly liable for insider trading on a set of highly unusual facts under the misappropriation theory—misappropriation of confidential information used to trade in securities in breach of a duty to the source of the information. According to Coffee, prior to Panuwat, cases involving the misappropriation theory “seem to have involved conduct by the defendant that caused ‘likely harm’ to the shareholders of the source of the information.”  But not so in Panuwat. Rather than a fiduciary obligation, he suggests, perhaps the duty that Panuwat breached was really a contractual duty owed to his employer? And, in that case, should the SEC be the party enforcing it? His arguments may be highly controversial—certainly the SEC would disagree—but thought-provoking nonetheless and definitely worth a read.
