Most recently known for his lucrative short position in Lehman Brothers, David Einhorn has made a name through his hedge fund Greenlight Capital.

Founded in 1996 with only $900K under management, Greenlight is perceived as one of the most respected value-oriented investment firms in the industry. Not to mention that Einhorn once finished in eighteenth place at the World Series of poker.

Yet, what is most impressive about this firm is its great ability to make significantly profitable short sale trades. "His shorts on Conseco, CompuCredit, Sirrom Capital, and Resource America -- some of the more spectacular corporate flameouts of the late nineties and early aughts -- each returned more than 80 percent," wrote New York Magazine, in a recent interview with the hedge fund superstar.

With that said, we will only focus on the long positions of this firm.

According to Greenlight's recent 13F SEC filing, the fund holds approximately $5B in equities traded in the big three (AMEX, NASDAQ, and NYSE), which implies a 7.3% increase from the previous filing.

Its biggest holding at the end of the previous quarter is Pfizer (NYSE: PFE), the New York based pharmaceutical giant. And among its most relevant ownership increases is Travelers, the insurance company that was once a part of the Citicorp family of the late 1990's.
