In fact, QTR's Chris Irons expected "Betting on Zero" to be to Herbalife what "Blackfish" was to SeaWorld Entertainment Inc (NYSE: SEAS ). SeaWorld shares have sunk 58 percent since the 2013 "Blackfish" release. "The impact of this movie I think is going to be far greater than anybody is discounting right now on the stock," he said before the release. He also predicted activist investor Carl Icahn to exit his Herbalife position — a stake of 22.5 million shares — between the film release and effecting of Federal Trade Commission sanctions in 2017.
