Michael Steinberg, a top portfolio manager at Steven A. Cohen's SAC Capital Advisors hedge fund, was found guilty Wednesday of charges that he traded on insider information.
A federal jury in Manhattan found Steinberg, 41, guilty on all five counts of conspiracy and securities fraud he faced.
Prosecutors said he traded on confidential information that was passed to him by an employee, who later admitted to swapping illegal tips with friends at other firms.
The verdict, delivered in the fifth week of trial, was the latest victory for federal prosecutors in a four-year crackdown on Wall Street insider trading that has resulted in convictions of 77 people.
Steinberg closed his eyes and put his head back when the first guilty finding was read. The verdict was delayed slightly when Steinberg fainted as it was about to be read. Jurors left the courtroom while he was attended to by paramedics and then returned to the courtroom.
Steinberg will be sentenced on April 25, the judge said.
The verdict came a month after SAC Capital agreed to pay $1.2 billion and plead guilty to fraud charges stemming from a long-running probe of insider trading at Cohen's hedge fund.
Steinberg, who worked in SAC's Sigma Capital Management division, was one of eight employees at SAC to face criminal charges for insider trading and the first of two to fight them at trial. A former SAC portfolio manager, Mathew Martoma, is scheduled to face trial Jan. 6.
Six others have pleaded guilty to charges relating to insider trading, including Jon Horvath, an SAC analyst who prosecutors said supplied Steinberg with nonpublic information about companies, including Dell Inc. and Nvidia Corp.
Horvath, 44, who cooperated with the government in hopes of avoiding jail time, became a star witness in the case against Steinberg, testifying over the course of nine days how his boss pushed him to get "edgy, proprietary" information.
