Herbalife

From MSN Money:

“Herbalife’s stock price sank sharply last week after hedge fund manager William Ackman said that he believes the nutritional supplements company is a pyramid scheme and that he has been shorting the stock for several months. The company has vehemently denied the claims several times.”

How was this a mystery to anyone?   Aren’t they analysts?  Couldn’t they figure that out when found out their sales force was made up of 63 year old overweight housewives espousing their nutritional advice and recommendations?
