NEW YORK – A former hedge fund portfolio manager has pleaded not guilty in New York to charges in a rewritten indictment that accuses him of pursuing an inside investment edge from more than 20 doctors.
Mathew Martoma entered the plea Friday in federal court in Manhattan.
Martoma was arrested in November on charges that he persuaded a medical professor to leak secret data from an Alzheimer's disease trial. Prosecutors say the inside information enabled other investment professionals at the hedge fund founded by Steven A. Cohen to earn a quarter-billion dollars illegally.
The new securities fraud indictment unveiled Thursday accused Martoma of seeking illegal information from other doctors from 2006 to 2008 while working at Cohen's SAC Capital Advisors.
The Boca Raton, Fla., resident remains free on bail.
