Every quarter, many money managers have to disclose what they've bought and sold. Their latest moves can shine a bright light on smart stock picks.
Today, let's look at highly regarded value investor David Einhorn and Greenlight Capital, which he founded. Einhorn's investing success as well as his advocacy of financial transparency and accountability have attracted many fans. Although he isn't afraid to short stocks, he prefers going long and looks for situations where he feels a stock is mispriced.
Greenlight's stock portfolio totaled $5.5 billion in value as of March 31, 2012, with about 41 holdings. The top three holdings, making up more than a quarter of the overall portfolio's value, are Apple, Seagate Technology, and General Motors.
So what does Greenlight Capital's latest quarterly 13F filing tell us? Here are a few interesting details:
New holdings include grocery store company Roundy's
Among holdings in which Greenlight increased its stake were DST Systems and Marvell Technology
Greenlight reduced its stake in companies such as Research In Motion
Finally, Greenlight unloaded several companies, such as OmniVision Technologies
We should never blindly copy any investor's moves, no matter how talented the investor. But it can be useful to keep an eye on what smart folks are doing. 13-F forms can be great places to find intriguing candidates for our portfolios.
