SAC Capital is currently in a world of hurt. The major investment firm is being indicted for insider trading with the government originally seeking ALL of its billions as punishment despite having already settled some of the issues to the tune of a $600 million fine. At first, most of us will think, "Let 'em burn." However, the amount of money borrowed, invested and leveraged by hedge funds as large as SAC have deeper implications (hedge funds control an estimated $2.25 trillion). Part of the reason the government was gunning for all of the firm's assets is that profits obtained from "dirty money" are themselves dirty and therefore seizable. And that extends beyond SAC into the markets that have also invested in and profited from SAC (which is most of Wall Street). The rest of Wall Street's traders are concerned, however, because as SAC's traders are indicted, they may also subject to scrutiny for basically bandwagoning when the illegal behavior should have been obvious. The investigation isn't scaring away all the investors, there are many that plan to continue riding the gravy train of SAC's run of success.
