NEW YORK - Wealthy hedge fund operator Raj Rajaratnam and a codefendant pleaded not guilty yesterday to charges they were major players in a scheme that used inside information to make stock trades that generated millions of dollars in profits.
Prosecutors, who have described the case as a “wake-up call for Wall Street,’’ promised to hand over to defense attorneys 100 hours of intercepted phone calls made over eight months that they say implicate the defendants.
Rajaratnam and Danielle Chiesi entered their pleas before US District Judge Richard Holwell in Manhattan to an indictment returned last week in a $52 million insider-trading case that has resulted in charges against 21 people.
