Amid facing federal insidertrading charges and client defections, SAC Capital Advisors LLP. has shrunk their holding positions in U.S. stocks by $2 billion during the second quarter. As of June 30 SAC, who is headed by Steven A. Cohen 16.2 billion worth of U.S. listed stocks. The companies that felt the effect of SAC selling off their shares were EQT Corp. (NYSE: EQT), who's shares fell $213.8 million in value, SAC was holding 3.32 million shares of the natural gas producer. Then Sirius XM Radio Inc. (NYSE:SIRI) which went down by $163.7 million as SAC got rid of the 53.2 million shares it was holding. I'm guessing SAC got rid of all these shares in order to prepare for any fines that might recieve from the insidertrading charges they are facing.
