Yesterday I profiled risk ratings. . this site profiles power ratings. It's brought to you compliments of Larry Connors' TradingMarkets.com. Larry is probably one of the sharpest stat guys in the business and his little gem "How Markets Really Work" is a marvel of statistical elegance and relevance. This is a handy little tool, and incredibly easy to use. They also profile a daily list of highest rated and lowest rated stocks, so no screening required! It's is a free site, although there is also a daytrader version that is fee based. Buy the 10s, sell the 1s. Let's hope CXO runs a performance test on it.
