Too many shorts? But what about you? Having too many people gambling and buying more of the stock than they can afford on margin is very destructive, and a negative influence on the stock. As weak investors have to sell out to meet margin calls that is destructive to the stock price. As I have said all along this is an excellent long term investment for those who are patient enough to wait for the revenue stream from the new drug sales. But, having too many margin gamblers and traders is not a positive influence on the stock.
