Regulatory Changes NeededThere is no reason that short reporting shouldn't be reported daily. As we see in the November 15 short report, short interest increased by 2,039,388 shares and the short sales coincide with the pullback in the stock price. At least some of the share price pullback has to be attributed to shareholders that sold their shares because they didn't know that shorters were selling shares that they don't even own.
So every other kind of market information can be published about a particular stock but short selling data is restricted. Some brokerage houses are more than likely monitoring short interest data and trading off of it before the information is made available to the public Isn't that a form of insider trader?
