Mathew Martoma’s not so sure.
As you may have heard, in addition to the salary he was paid by the University of Michigan, Dr. Sidney Gilman made about $100,000/year through his side-gig advising "a wide network of Wall Street traders." That network included included Mathew Martoma, recently charged with running “the most lucrative insider trading scheme ever,” based on the information he received from Gilman, who made it a habit of leaking highly confidential information to the former SAC Capital employee. While most people that engage in fraud can't help but spend their ill-gotten gains in a flashy way that attracts unwanted attention (expensive cars, private jets, chinchilla fur coats) the Times reports that Sid Gilman's supplementary income "was not readily apparent in his lifestyle in Michigan." For instance, no second home and no bragging to his colleagues about his life on Wall Street. Still, on at least one occasion, the doctor couldn't help but let the underage girl sitting next to him on a flight home know that she was in the presence of a BSD.
