(Bloomberg) -- Jim Chanos, the legendary short seller known for his bearish bets against Enron and Tesla Inc., is shuttering his hedge funds after almost four decades. Chanos & Co., which he founded as Kynikos Associates in 1985, plans to return most capital to investors by the end of the year, according to a letter to clients Friday. “It is no secret that the long/short equity business model has come under pressure and interest in fundamental stock pickers has waned,” Chanos wrote.
