How do you find the standard deviation of a stock
I think you are better off looking at the Beta of a stock, which is the standard deviation of the stock times its correlation with the market divided by the standard deviation of the market. [math]\beta=\frac{Cov(R_e,R_p)}{Var(R_p)}=SD(R_e)\frac{ Standard deviation is a statistical term that measures the amount of variability or dispersion around an average. Standard deviation is also a measure of volatility. Generally speaking, dispersion is the difference between the actual value and the average value. The larger this dispersion or variability is, the higher the standard deviation. Standard deviation is a measure of risk that an investment will not meet the expected return in a given period.
