Greenlight Capital's Q1 Letter: Sees Tech Bubble Forming

David Einhorn's hedge fund firm Greenlight Capital is out with is first quarter letter.  In it, they talk about how a potential bubble in tech is forming.  As such, they've shorted a basket of momentum names in small size in order to manage risk.

Other main takeaways from the letter include various new longs for Greenlight: Resona Holdings (Japan: 8308), SunEdison (SUNE), Altice (Netherlands:ATC), and Conn's (CONN).  The last long might be a surprise to some, as many hedge funds have been short the retailer that also deals in subprime lending. 

Greenlight also covered many unsuccessful shorts, including Chipotle (CMG), Fortescue Metals, Loblaw Companies, and Michael Kors (KORS).

At the end of Q1, their largest long positions were Alpha Bank, Apple, gold, Marvell Technology, Micron, and Oil States International.
