Herbalife Ltd. shares rose after a profanity-filled battle on live television between two billionaire investors with vastly different views of the Los Angeles company.
Bill Ackman, who has an enormous short position on Herbalife and has called the company a pyramid scheme, and Carl Icahn, who reportedly has a long position on the company, traded personal insults during a nearly 30-minute telephone discussion aired live Friday on CNBC.
Icahn called Ackman a "liar" and said: "He's got one of the worst reputations on Wall Street."
Ackman countered: "The big issue about Carl Icahn is he's not used to someone standing up to him, particularly a little guy like me."
At one point, the show's host, Scott Wapner, reminded Icahn that he was on live television and asked him to refrain from using profanity.
