Former SAC Capital Advisors LP portfolio manager Mathew Martoma will go on trial Nov. 4 on charges he helped the hedge fund founded by Steven A. Cohen make $276 million using illegal tips about an Alzheimer’s drug, Reuters reported yesterday. U.S. District Judge Paul Gardephe set the jury trial date yesterday after Martoma’s lawyer, Richard Strassberg, said at a hearing that prosecutors told him they might file a superseding or revised indictment that would include additional information. The government’s deadline to file insider trading charges in the case expires in late July.
