A former hedge fund portfolio manager accused of enabling a quarter of a billion dollars in profits by passing along inside information in one of the largest insider trading fraud cases in history appeared in a Manhattan court for the first time yesterday and was released on $5 million bail, though his movements were restricted.

Mathew Martoma, 38, of Boca Raton, Fla., was read his rights by Southern District Magistrate Judge James Cott (See Profile), who agreed to impose a bail package that prosecutors and Martoma’s lawyers had worked out after his initial court appearance in Florida last week.
