expected to the retum b er is calculate the the propean Pxpected rate of return = 1 - Part+P + ... + P measures of standalone risk are standard deviation coefficient of antion, and the Sharper Standard deviation is a statistical measure The select an asset's probability distribution, the lower its risk. These variability of a set of bervations as shown below Standard deviation --- n - )' If you have a sample of actual historical data, then the standard deviation calculation would be changed as follows: S- investments with us The coefficient i on is a better measure of and work than standard deviation be t i n a measure of per it is the coefficient of variation shows the per of return, so it provides a more meaningful m ure when the expected return on two alternatives ar e The Sharpe ratio compares the asset's reared excess return to its Select over a specified . Excretum sure the amount that investment returns are above the street returns equal to the risk tree rate will have at Sharpe t ow that over a diven med invest with Select Share to performed better because the greated per unit of risk.
