Ex-SAC trader Martoma seeks to toss insider trading conviction

By Jonathan Stempel NEW YORK (Reuters) – Former SAC Capital Advisors LP portfolio manager Mathew Martoma asked a U.S. judge to throw out his insider trading conviction, saying federal prosecutors did not prove he committed a crime and that improper evidence and jury bias tainted the verdict. The request submitted late Thursday night in the U.S. District Court in Manhattan was expected. It followed Martoma's February 6 conviction on two counts of securities fraud and one count of conspiracy. "This court should enter a judgment of acquittal on all counts," Martoma, 39, told U.S. District Judge Paul Gardephe, who presided over the roughly month-long trial, in the filing.
