I am in favor of the uptick rule as proposed by the SEC. In my observations of the Market, the unbridled attack on stock prices has been a major factor in the most recent down turn.

However the issue of naked shorting has personally affected me by reducing the performance of a stock I owned. Naked shorting supports the notion of infinite stock issuance, if temporary. It is unreasonable that this is allowed to continue.
