NEW YORK--Federal prosecutors filed new charges Tuesday against employees at three hedge funds accused of making improper trades on inside information.

The new charges relate to short sales of NVIDIA Corp. (NVDA) stock in April and May 2009. Those charged Tuesday were Todd Newman, a former portfolio manager with hedge-fund firm Diamondback Capital Management; Anthony Chiasson, a former hedge-fund manager at Level Global Investors LP; and Jon Horvath, a technology analyst with SAC Capital Advisors LP's Sigma Capital Management division.

The new charges broaden the case against Messrs. Newman, Chiasson and Horvath, who were originally charged in January with engaging in a "criminal club" that prosecutors said netted more than $61.8 million through improper trades of stock, including shares of Dell Corp. (DELL) stock.

All three men had pleaded not guilty to the original charges in February.

The new, superseding indictment filed in Manhattan federal court Tuesday contains three new charges against the defendants related to transactions of NVIDIA stock, saying they traded nonpublic information in advance of NVIDIA's quarterly financial results reported in May 2009.

The new indictment accuses Mr. Newman of short selling 375,000 shares of NVIDIA stock in April 2009 based on nonpublic information. Mr. Chiasson is accused of improperly short selling 1 million shares of NVIDIA stock in May 2009. Mr. Horvath is accused of an improper swap transaction equivalent to a short sale of 160,000 shares of NVIDIA stock in May 2009. A short sale involves a bet that a stock will lose value.

The earlier indictment had charged the three men with improper trades of only Dell stock, although it referenced the sharing of nonpublic information about NVIDIA.

Prosecutors have said a larger number of stocks could be at issue at their trial, which is set to begin Oct. 29.

An attorney for Mr. Newman declined to comment on the new charges. Attorneys for Messrs. Chiasson and Horvath could not immediately be reached for comment.

The case is one of many high-profile insider-trading cases recently. Earlier this year, Rajat Gupta, a former director of Goldman Sachs Group Inc. (GS) and Procter & Gamble (PG), was found guilty of conspiracy and securities fraud for passing on insider information to Galleon Group hedge fund founder Raj Rajaratnam.

This year, federal authorities in New York told The Wall Street Journal they were seeking to build cases against 120 others suspected of having violated insider-trading laws.
