DEFINITION of 'Standard Deviation'. 1. A measure of the dispersion of a set of data from its mean. The more spread apart the data, the higher the deviation. Standard deviation is calculated as the square root of variance.2. In finance, standard deviation is applied to the annual rate of return of an investment to measure the investment's volatility. measure of the dispersion of a set of data from its mean. The more spread apart the data, the higher the deviation. Standard deviation is calculated as the square root of variance. 2.
Standard deviation is also a component in the Sharpe Ratio, which assesses risk-adjusted performance. For example, Fund A has a standard deviation of 23.56%. This means that approximately 68% of the time, Fund A will be within 23.56% of its mean of 25.33.This statistical measurement of dispersion about an average, depicts how widely a mutual fund's returns varied over a certain period of time.or example, for a fund with a mean annual return of 10% and a standard deviation of 2%, you would expect the return to be between 8% and 12% about 68%of the time, and between 6% and 14% about 95% of the time.
