Federal prosecutors are examining trades made in an account run by Mr. Cohen at SAC Capital Advisors, his hedge fund in Stamford, Conn., that manages about $12 billion, according to a government filing. The trades were suggested by two SAC portfolio managers who have pleaded guilty to insider trading-related crimes. The charges are part of a vast investigation into insider trading at hedge funds by the United States attorney in Manhattan that has resulted in criminal cases against at least 47 people over the last two years.
