Consider the annual returns produced by two different active equity portfolio managers (A and B) as well as those to the stock index with which they are both compared: -Select- % % -Select- Period 1 2 3 4 5 6 7 8 9 10 a. Did either manager outperform the index, based on the average annual return differential that he or she produced relative to the benchmark? Use a minus sign to enter negative values, if any. Do not round intermediate calculations. Round your answers to two decimal places. Manager A: Manager B: % Manager A 13.6% -3.0 14.5 0.7 -7.5 24.3 -11.7 5.0 2.4 19.1 % Manager B 13.5% -4.7 13.9 2.1 -5.7 26.0 -12.1 5.3 3.7 18.0 's average return is less than the index and -Select- 's average exceeded that of the index. b. Calculate the tracking error for each manager relative to the index. Which manager did a better job of limiting his or her client's unsystematic risk exposure? Do not round intermediate calculations. Round your answers to two decimal places. Manager A: Manager B: Index 11.0% -2.2 18.8 -0.7 -3.9 21.3 -13.3 5.5 2.6 19.5 did the better job of limiting the client's exposure to unsystematic risk as the difference between manager's returns and those of the index has a -Select-standard deviation
