A French doctor and a California sales manager on Wednesday became the latest to be sentenced after being convicted in a recent federal crackdown on insider trading at hedge funds.

Dr. Yves Benhamou was sentenced to time served and three years supervised release after he cooperated with an insider-trading investigation and pleaded guilty to leaking secrets to a hedge fund manager about the biotech company Human Genome Sciences. Dr. Benhamou served as an adviser on a clinical drug trial.

In a separate case, a former Silicon Valley sales manager, James Fleishman, was sentenced to two-and-a-half years of imprisonment and two years supervised release for helping to convey inside information to hedge funds. The confidential information included revenue or margin numbers from executives at companies, including Advanced Micro Devices and Dell.

In imposing Mr. Fleishman’s sentence, Federal District Judge Jed S. Rakoff emphasized the need for deterrence. He said prosecutors in New York had been bringing insider-trading cases for 30 to 40 years, “and yet the prosecutions have not done enough to deter this serious and sophisticated crime.”
