Short selling should be banned. The practice is a tool used by profiteers to manipulate stock prices. Naked shorting is supposedly banned. I doubt if the law put much of a dent in the practice. This is especially true of smaller, more vulnerable companies. I use Celsci as an example. There is greatly suspected that Iroquois Master Funds is involved with bringing a lawsuit against Celsci after shorting the stock. What can the average shareholder prove with no resources? Short selling should be banned.
