WSJ – Federal prosecutors are looking into alleged improper trading involving more than a dozen companies not previously disclosed in an insider-trading probe that has ensnared several hedge fund executives, including Galleon Group founder Raj Rajaratnam.
In a March 22 letter, prosecutors from the U.S. Attorney’s office in Manhattan disclosed they believe Rajaratnam and other co-conspirators shared material nonpublic information or made improper trades in the securities of Goldman Sachs Group, AT&T Inc., Cisco Systems Inc., and 18 other companies that had not been named publicly.
