  • Return since the call: -74%

Einhorn is the king of the shorts. The manager of $10 billion hedge fund Greenlight Capital famously, or perhaps infamously, predicted the downfall of Lehman Brothers during a public presentation in May 2008.

His tear-down of Green Mountain Coffee Roasters (GMCR) may not have been as epic, but Einhorn's insights have crushed shares of what was one of the best-performing stocks of 2011 before his presentation.

Many of Einhorn's predictions have come true: Green Mountain's lock on the K-cup market has been challenged, and in turn, its earnings have taken a hit.

Einhorn can even send a company's stock reeling simply by asking questions during a conference call. Since Einhorn popped up on Herbalife's (HLF) analyst call in May and questioned the company's accounting metrics, shares of the nutritional supplement manufacturer have taken a drubbing. Herbalife's stock has fallen 35% since the call.
