Consider the rate of return of stocks ABC and XYZ. Year 1 2 3 4 ABC 20% 12 19 4 2 XYZ 32% 12 19 1 -7 a. Calculate the arithmetic average return on these stocks over the sample period. (Do not round intermediate calculations. Round your answers to 2 decimal places.) Arithmetic Average ABC XYZ % % b. Which stock has greater dispersion around the mean return? ABC O XYZ c. Calculate the geometric average returns of each stock. What do you conclude? (Do not round intermediate calculations. Round your answers to 2 decimal places.) Geometric Average ABC XYZ d. If you were equally likely to earn a return of 20%, 12%, 19%, 4%, or 2%, in each year (these are the five annual returns for stock ABC), what would be your expected rate of return? (Do not round intermediate calculations. Round your answers to 2 decimal places.) Expected rate of return % e. What if the five possible outcomes were those of stock XYZ? (Do not round intermediate calculations. Round your answers to 2 decimal places.) Expected rate of return % f. Given your answers to (d) and (e), which measure of average return, arithmetic or geometric, appears more useful for predicting future performance? Arithmetic O Geometric
