Winifred Jiau Pleads Not Guilty to Insider-Trading Charges

Winifred Jiau, a former consultant to Primary Global Research LLC, pleaded not guilty to conspiracy and securities-fraud charges as part of an insider-trading investigation.

Jiau, 43, passed inside information on to an unnamed hedge fund portfolio manager and to Noah Freeman, the Boston hedge fund manager who pleaded guilty Feb. 7 to securities fraud, prosecutors said in an indictment made public earlier today in federal court in New York.

Jiau passed tips on Nvidia Corp. and Marvell Technology Group Ltd. to the two men, according to the indictment. She was paid as much as $10,000 a month in return. Jiau, who is being held in a federal jail in Manhattan, was originally charged Dec. 29 in a criminal complaint.

Her lawyer, Frederick Hafetz, declined to comment on the indictment.

The case is U.S. v. Jiau, 10-mj-02900, U.S. District Court, Southern District of New York (Manhattan).
