If you have a sample of actual historical data, then the standard deviation calculation would be changed as follows: Estimated - - N-1 The coefficient of variation is a better measure of stand-alone risk than standard deviation beause it is a standardized measure of risk per unit; it is caloulated as the stancdare Cevation return. The coeficient of variation shows the risk per unit of retum, so it provides a more meaningful risk measure when the expected returns on two altermatives are not entical Quantitative Problem: You are given the following probability distribution for CHC Enterprises: dvided by th Probability Strong Normal Weak 0.25 0.5 0.25 22% 8% .5% What is the stock's expected return?
