in stock prices in early 2013.
But relying on the filings to develop an investment strategy comes with some peril because the disclosures are backward looking and come out 45 days after the end of each quarter.
Still, the filings can offer a glimpse into what hedge fund managers saw as opportunities to make money on the long side. The filings don't disclose short positions, bets that a stock will fall in price. And there's also little disclosure on bonds and other securities that don't trade on exchanges.

Farallon, founded by recently retired billionaire Thomas Steyer, took a new stake in retailer Sally Beauty Holdings of 4.7 million shares, and Jana initiated a new position in retailer Fifth & Pacific Companies (formerly Liz Claiborne Inc) of 3.3 million shares.
Tiger Consumer Management cut its stake in luxury retailer Michael Kors Holdings Ltd by 394,269 shares to 1.6 million.
Eton Park Capital Management, a $12 billion hedge fund run by former Goldman Sachs trader Eric Mindich, initiated a new position in Best Buy Co of 1.6 million shares during the fourth quarter. Best Buy was one of the best performing stocks in January, up over 37 percent.
Tiger Global Management, a roughly $6 billion fund run by Chase Coleman and Feroz Dewann, loaded up on Amazon Inc . Tiger Global now owns 1.23 million shares, up from 480,000.
Tiger Global trimmed its stake in Apple, to 1.05 million shares from 1.3 million, and sold all of its 698,000 shares of Google Inc and its 11.7 million-share stake in Facebook Inc. Tiger slashed its Yahoo Inc position to 14 million shares from 25 million.
JAT Capital, founded and run by John A. Thaler, slashed its stake in Facebook to about 530,000 shares, significantly down from 6.1 million. But JAT opened a new stake in Yahoo of 2.8 million shares. It also re-entered LinkedIn with about 340,000 shares, after dissolving a stake some time in the third quarter.
