## How to find standard deviation of two stocks

Expected Return and Standard Deviations of Returns. Stock. A Calculate the alpha for each of portfolio A and B using the capital asset pricing model. (CAPM).

Standard deviation is the statistical measure of market volatility, measuring how widely prices are dispersed from the average price. If prices trade in a narrow trading range, the standard deviation will return a low value that indicates low volatility. This simple scan searches for S&P 600 stocks that are in an uptrend. The final scan clause excludes high volatility stocks from the results. Note that the standard deviation is converted to a percentage of sorts so that the standard deviation of different stocks can be compared on the same scale. Owing to the diversification benefits, standard deviation of a portfolio of investments (stocks, projects, etc.) should be lower than the weighted average of the standard deviations of the individual investments. Formula. Portfolio standard deviation for a two-asset portfolio is given by the following formula: Standard Deviation Example. An investor wants to calculate the standard deviation experience by his investment portfolio in the last four months.
