Compute the arithmetic mean annual rate of return for each stock. Which stock is most desirable by this measure? (4 Points) b. Compute the standard deviation of the annual return for each stock. By this measure which is the preferable stock? (4 points) C. Compute the coefficient of variation for each stock. By this relative measure of risk, which stock is more preferable? (4 points) d. Compute the geometric mean rate of return for each stock. Discuss the difference between the arithmetic mean return and geometric mean return.
