I trade high-momentum stocks that are showing signs of technical buying exhaustion. Typically, there are only one to two stocks that meet this screen each day. Examples over the last few weeks are Dendreon ( DNDN), Cell Genesys ( CEGE), Dyax ( DYAX) and InsWeb ( INSW). In each case, I enter a short and wait for the inevitable drop. 2) What's your style of investing? Are you daytrading, or making longer-term picks? While my investing style is low-risk/long-term, this strategy doesn't work in a competition like "Beat the Street." You have to look for stocks that are event-driven. Over many years of studying the markets, I have developed a set of technical indicators which, when weighted properly, roughly signal when buying has reached its exhaustion levels. I usually enter into these situations by selling short and covering the next day. Across the equity markets, only one to two stocks per day meet the screen criteria, so it takes very little time away from work or family. 3) Do you primarily trade on the long or short side? Any stocks that have been particularly good from both sides? Over 90% of the trades I have made are from the short side. Having said that, I believe the uranium stocks are where the hot money is going right now. Names like Uranerz ( URZ), Energy Metals ( EMU) and Uranium Resources ( URRE) are in the early stages of a huge bull market and are up 50% or more in the last two months. These are all good long candidates.
