A former Wall Street titan was convicted Wednesday of making a fortune by coaxing a crew of corporate tipsters into giving him an illegal edge on blockbuster trades in technology and other stocks — what prosecutors called the largest insider trading case ever involving hedge funds.

Raj Rajaratnam was convicted of five conspiracy counts and nine securities fraud charges at the closely watched trial in federal court in Manhattan. The jury had deliberated since April 25, and at one point was forced to start over again when one juror dropped out due to illness.

Prosecutors alleged the 53-year-old Rajaratnam made profits and avoided losses totaling more than $60 million from illegal tips. His Galleon Group funds, they said, became a multibillion-dollar success at the expense of ordinary stock investors who didn't have advance notice of the earnings of public companies and of mergers and acquisitions.

A New York jury has quietly finished its second week without a verdict in the trial of a one-time billionaire hedge fund founder accused of using inside information to make tens of millions of dollars illegally.

Prosecutors say Rajaratnam used a network of friends and old college buddies to cheat on Wall Street. His lawyers say he only traded based on public information. The replacement of a juror two days ago forced the jury to restart its work.
