SEC "Canvassing All Hedge Funds for Aberrational Performance"
According to the Wall Street Journal (link below), the U.S. Securities and Exchange Commission (SEC) "is scrutinizing hedge funds that consistently offer above-market returns amid concern about whether outsized returns are a result of malfeasance".
According to SEC enforcement director Robert Khuzami, any hedge fund that is beating market indexes by 3% and "doing it on a steady basis" will be subject to scrutiny.

The SEC lacks the necessary manpower to thoroughly scrutinize each and every hedge fund in existence, so there are hoping to create a short list of hedge funds that have potentially broken the law by identifying those that have consistently beaten market indexes by a substantial margin.
Firms such as SAC Capital, Paulson + Co. Inc., Renaissance Technologies, etc - consider yourselves warned.
