QUESTIONS AND CASE PROBLEMS
Question 1
Issue Presented: Is it illegal insider trading for a psychiatrist to trade on information that a
patient reveals during therapy? Is his broker liable? Is their conduct ethical?
Under the misappropriation theory, the SEC must show that (1) the defendant converted
material, nonpublic information, (2) in breach of a fiduciary duty, (3) in connection with the
purchase or sale of securities, and (4) the defendant acted with scienter. If the defendant is a
tippee, the SEC must further prove that the tippee traded on the misappropriated information
when he knew or should have known it was misappropriated.
Sloate also contended that the SEC’s complaint should have been dismissed because Dr.
Willis’s misconduct did not defraud the investing public or Joan Weill as an investor. Again, the
court disagreed: Rule 10b-5 is broadly worded to require only that the plaintiff show that the
defendant acted in a manner that constituted a fraud or deceit upon any person. The court
found it sufficient that the fraud was committed upon Weill in her capacity as a patient of
Willis.
Consequently, both defendants were held liable for Rule 10b-5 violations under the
misappropriation theory, later embraced by the U.S. Supreme Court in United States v. O’Hagan,
521 U.S. 642 (1997). In addition to the illegal (and necessarily unethical) behavior involved in
the trades, Willis’s behavior in revealing information told in confidence by a patient is highly
unethical and usually can be disciplined by professional associations.
