Last Thursday, the Dow Industrials fell nearly 400 points on widespread fears that the subprime mortgage credit fallout will spread to other areas of the economy, and significantly damage overall economic growth. On Friday, the Dow fell over 200 points before closing fractionally lower. In a situation like this, with the major indexes making huge gains and taking huge losses in the span of just 2 days, what can you do to gain an edge in the market? (Here's a hint: Don't watch the television for ideas!)
TradingMarkets offers a proprietary stock rating method called PowerRatings (for Traders). This method ranks stocks 1-10 and the higher the rating, the greater the one-week historical gain has been. Stocks rated 9 and 10 have outperformed the average stock by 12 to 1 since 1995 and ideally are the stocks to focus on each day. Stocks rated 1 and 2 on average have lost money, and you want to know these stocks in order to avoid them. To validate PowerRatings performance, more than 8.2 million daily trades were looked at from Jan. 1, 1995 to Dec. 1, 2005 -- over 10 years worth of data. The results are based on the average 5-day performance.
Last week, we highlighted a few potential trade ideas, pointing out what the stock's PowerRating was at the time, and how the stock had been performing lately. Just on Friday, we had two big winners which we chose solely on their PowerRatings. We do not look for things like earnings or news; we look for time-tested, historical edges which are backed by hard data.
