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 23%, 8%, 10%, 3%, or 3%, 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? O Arithmetic O Geometric
