A) Eugene Fama B) Michael Jensen C) William Sharpe D) Jack Treynor E) A and B Answer: A Difficulty: Easy R
5、ationale: Michael Jensen, William Sharpe, and Jack Treynor developed popular models for mutual fund performance evaluation. 4. Henriksson (1984) found that, on average, betas of funds _ during market advances A) increased very significantly B) increased slightly C) decreased slightly D) decreased ve
6、ry significantly E) did not change Answer: C Difficulty: Moderate Rationale: Portfolio betas should have a large value if the market is expected to perform well and a small value if the market is not expected to perform well; thus, these results reflect the poor timing ability of mutual fund manager

A) outperform the S&P 500 index on both raw and risk-adjusted return measures B) underperform the S&P 500 index on both raw and risk-adjusted return measures C) outperform the S&P 500 index on raw return measures and underperform the S&P 50
8、0 index on risk-adjusted return measures D) underperform the S&P 500 index on raw return measures and outperform the S&P 500 index on risk-adjusted return measures E) match the performance of the S&P 500 index on both raw and risk-adjusted return measures Answer: B Difficulty: Moderate Rationale: Mo
9、st mutual funds do not consistently, over time, outperform the S&P 500 index on the basis of either raw or risk-adjusted return measures. 6. Suppose two portfolios have the same average return, the same standard deviation of returns, but portfolio A has a higher beta than portfolio B. According to t
10、he Sharpe measure, the performance of portfolio A _. A) is better than the performance of portfolio B B) is the same as the performance of portfolio B C) is poorer than the performance of portfolio B D) cannot be measured as there is no data on the alpha of the portfolio E) none of the above is true
11、. Answer: B Difficulty: Moderate Rationale: The Sharpe index is a measure of average portfolio returns (in excess of the risk free return) per unit of total risk (as measured by standard deviation). 7. Consider the Sharpe and Treynor performance measures. When a pension fund is large and has many ma
12、nagers, the _ measure is better for evaluating individual managers while the _ measure is better for evaluating the manager of a small fund with only one manager responsible for all investments. A) Sharpe, Sharpe B) Sharpe, Treynor C) Treynor, Sharpe D) Treynor, Treynor E) Both measures are equally
13、good in both cases. Answer: C Difficulty: Moderate Rationale: The Treynor measure is the superior measure if the portfolio is a small portion of many portfolios combined into a large investment fund. The Sharpe measure is superior if the portfolio represents the investors total risky investment posi
14、tion. 8. Suppose you purchase 100 shares of GM stock at the beginning of year 1, and purchase another 100 shares at the end of year 1. You sell all 200 shares at the end of year 2. Assume that the price of GM stock is $50 at the beginning of year 1, $55 at the end of year 1, and $65 at the end of ye
15、ar 2. Assume no dividends were paid on GM stock. Your dollar-weighted return on the stock will be _; your time-weighted return on the stock. A) higher than B) the same as C) less than D) exactly proportional to E) more information is necessary to answer this question Answer: A Difficulty: Moderate R
16、ationale: In the dollar-weighted return, the stocks performance in the second year, when 200 shares are held, has a greater influence on the overall dollar-weighted return. The time-weighted return ignores the number of shares held. 9. Suppose the risk-free return is 4%. The beta of a managed portfo
17、lio is 1.2, the alpha is 1%, and the average return is 14%. Based on Jensens measure of portfolio performance, you would calculate the return on the market portfolio as A) 11.5% B) 14% C) 15% D) 16% E) none of the above Answer: A Difficulty: Difficult Rationale: 1% = 14% - 4% + 1.2(x - 4%); x = 11.5
18、%. 10. Suppose the risk-free return is 3%. The beta of a managed portfolio is 1.75, the alpha is 0%, and the average return is 16%. Based on Jensens measure of portfolio performance, you would calculate the return on the market portfolio as A) 12.3% B) 10.4% C) 15.1% D) 16.7% E) none of the above An
19、swer: B Difficulty: Difficult Rationale: 0% = 16% - 3% + 1.75(x - 3%); x = 10.4%. 11. Suppose the risk-free return is 6%. The beta of a managed portfolio is 1.5, the alpha is 3%, and the average return is 18%. Based on Jensens measure of portfolio performance, you would calculate the return on the m
20、arket portfolio as A) 12% B) 14% C) 15% D) 16% E) none of the above Answer: A Difficulty: Difficult Rationale: 3% = 18% - 6% + 1.5(x - 6%); x = 12%. 12. Suppose a particular investment earns an arithmetic return of 10% in year 1, 20% in year 2 and 30% in year 3. The geometric average return for the
21、year period will be _. A) greater than the arithmetic average return B) equal to the arithmetic average return C) less than the arithmetic average return D) equal to the market return E) cannot tell from the information given Answer: C Difficulty: Moderate Rationale: The geometric mean will always b
22、e less than the arithmetic mean unless the returns in all periods are equal (in which case the two means will be equal). 13. Suppose you buy 100 shares of Abolishing Dividend Corporation at the beginning of year 1 for $80. Abolishing Dividend Corporation pays no dividends. The stock price at the end
23、 of year 1 is $100, the price $120 at the end of year 2, and the price is $150 at the end of year 3. The stock price declines to $100 at the end of year 4, and you sell your 100 shares. For the four years, your geometric average return is A) 0.0% B) 1.0% C) 5.7% D) 9.2% E) 34.5% Answer: C Difficulty
24、: Difficult Rationale: (1.25)(1.20)(1.25)(0.6667)1/4 - 1.0 = 5.7% 14. You want to evaluate three mutual funds using the information ratio measure for performance evaluation. The risk-free return during the sample period is 6%, and the average return on the market portfolio is 19%. The average return
25、s, residual standard deviations, and betas for the three funds are given below. The fund with the highest information ratio measure is _. A) Fund A B) Fund B C) Fund C D) Funds A and B are tied for highest E) Funds A and C are tied for highest Answer: B Difficulty: Difficult Rationale: Information r
26、atio = P/(eP); A: P = 20 - 6 - .8(19 - 6) = 3.6; 3.6/4 = 0.9; B: P = 21 - 6 - 1(19 - 6) = 2.0; 2/1.25 = 1.6; C: P = 23 - 6 - 1.2(19 - 6) = 1.4; 1.4/1.20 = 1.16. 15. You want to evaluate three mutual funds using the Sharpe measure for performance evaluation. The risk-free return during the sample per

A) Fund A B) Fund B C) Fund C D) Funds A and B are tied for highest E) Funds A and C are tied for highest Answer: C
28、Difficulty: Moderate Rationale: A: (24% - 6%)/30% = 0.60; B: (12% - 6%)/10% = 0.60; C: (22% - 6%)/20% = 0.80; S&P 500: (18% - 6%)/16% = 0.75. 16.
