Icahn's Eating Ackman's Lunch & Teaching Him How to Trade

When I first learned of Bill Ackman's thesis and subsequent short position in Herbalife (HLF), I thought I smelled a rat. I say that not because I dislike the mega-successful hedge-fund manager, but because of how he chose to divulge his short position and how he took on his short exposure. I thought shorting a hard-to-borrow stock rather than buying puts was his first monumental mistake.
