Date: 02/01/2000 10:34 AM Subject: File # S7-24-99 Dear Sirs: I would like to take this opportunity to provide you my comments on your Short Sales concept release. In very simple terms, the SEC needs to move to tighten controls on short sales, if not eliminate their wide spread availability. While it may be true that market makers use the short sale to make up for temporary short falls in supply, that action does not necessarily provide for proper valuation of the underlying security. When demand exceeds supply, the price should rise, not be held down due to short selling. My real concern, however, is the use of short sales as a panic tool by bear raiders. Organizations with access to large supplies of capital can force down a stock price to create a retail panic. This spiral effect hurts the retail investor and allows the short sellers to cover at a price that is artificially low. This is, by definition, manipulation. Lastly, I believe the anonymous short selling provided by Instinet needs to be completely halted. All transactions need to be made public, including short sales. Thanks you for your consideration.
