There is no doubt that his company was massively shorted. As it turns out, that was the right bet to make on this company.
However, the REAL problem is that there are still people out there who think today's events are the consquence of people shorting Overstock.
Overstock didn't walk off a cliff today because people shorted its shares. People shorted its shares because they realized the company was about to walk off a cliff.
