"Activist investor Bill Ackman, the CEO of Pershing Square Capital Management, gave an epic presentation on his latest short — Herbalife.
Ackman, whose hedge fund has an "enormous" short position, believes the multi-level marketing company that sells weight management and nutritional supplements is a pyramid scheme.
He also has a price target of $0 and believes the company is going to fail."

He is going to donate any personal profit to charity.
