Beta II for Metastock
This formula calculates Beta which is a measure of volatility of one security against another. This is typically used to measure the volatility of a stock against an index like the S&P 500. A value greater than one indicates the stock is more volatile than the index.
Note: This formula is set to calculate beta over 21 periods. To change the time periods replace each instance of 21 in the formula with the desired number of periods.
