The lawsuit is related to the alleged arranged trades of its former portfolio manager Mathew Martoma for certain hedge funds for its shares of Wyeth Limited (NSE:WYETH) (BOM:500095) and Elan Corporation, plc (NYSE:ELN). In December last year, federal investigators started another probe against SAC Capital Advisors involving its trades in shares of Weight Watchers (WTW) and InterMune (ITMN) from 2010 to 2011. SAC Capital Advisors is also waiting for the decision of prosecutors whether they would file criminal charges against Michael Steinberg, one of the longest-tenured portfolio managers of the hedge fund.
