Estimated=N1i=1(ftPA+2) The coefficient of variation is a better measure of stand-alone risk than standard deviation because it is a standardized measure of risk per unit; it is calculated as the divided by the expected retum. The coefficient of variation shows the risk per unit of return, so it provides a more meaningful risk measure when the expected returns on two alternatives are not The Sharpe ratio compares the asset's realized excess retum to its over a speafled period. Excess returns measure the amount that investment retums above the risk-free rate - so investments with retums equal to the risk-free rate will have a Sharpe ratio. It follows that over a given time period, Investments wi sharpe ratios performed better, because they generated excess returns per unit of risk. The sharpe ratio is calculated as: Sharperatio=(ReturnRisk-freerate)/ Quantitative Problem: You are given the following probability distribution for CHC Enterprises: What is the stock's expected return? Do not round intermediate calculations, Round your answer to two decimal ploces, \% What is the stock's standard deviation? Do not rownd intermediate calculations. Mound your answer to two decimal places. W What is the stock's coefficient of variation? Do not round intermediate calculations. Round your snswer to two decimal places.
