>>>>>>>>>>>>>>>>>>Beta Calculated The number is calculated for you (thank goodness) using regression analysis. The whole market, which for this purpose is considered the S&P 500, is assigned a beta of 1. There is no single index used to calculate beta, although the S&P 500 is probably the most common proxy for the market as a whole. Stocks that have a beta greater than 1 have greater price volatility than the overall market and are more risky. Stocks with a beta of 1 fluctuate in price at the same rate as the market. Stocks with a beta of less than 1 have less price volatility than the market and are less risky. http://stocks.about.com/od/evaluatingstocks/a/beta120904.htm ..low volatility linearity can be applied to stock screens: Criteria: Beta less then 1.0 Making new 52 wk highs (long candidates) Making new 52 wk lows (short candidates) Now you just need to find a stocks screener that lets you screen for this.
