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. Standard deviation is a measure of the dispersion of a set of data from its mean . It is calculated as the square root of variance by determining the variation between each data point relative to 17) Stock A has a beta of 1.2 and a standard deviation of returns of 14%. Stock B has a beta of 1.8 and a standard deviation of returns of 18%. If the risk-free rate of return increases and the market risk premium remains constant, then A) the required return on stock B will increase more than the required return on stock A. The formula to calculate the true standard deviation of return on an asset is as follows: where r i is the rate of return achieved at ith outcome, ERR is the expected rate of return, p i is the probability of ith outcome, and n is the number of possible outcomes.
