The spat between Ackman and Carl Icahn on CNBC was probably the most entertaining half-hour of TV I have ever watched. It's not just other investors trying to profit: Herbalife Chief Executive Officer Michael Johnson is quickly pushing for a new audit that will enable the company to buy shares and decrease the float by 30%.
