	Sharpe Measure	Treynor Measure	Jensen Measure
Portfolio A	0.25	0.12	0.04
Portfolio B	0.65	0.09	0.03
Portfolio C	0.45	0.11	0.02
Portfolio D	0.75	0.10	-0.02

The table represents risk-adjusted returns across all fund categories. Which of the following represents the best risk-adjusted return?

A)  Portfolio B.

B)  Portfolio C.

C)  Portfolio A.

D)  Portfolio D.

The correct answer is D

The Sharpe measure should be used since all funds are considered. Portfolio D should be selected because it has the highest Sharpe measure.

27、The Treynor and Sharpe ratios will:

A) give identical rankings when the assets have identical standard deviations.

B) give identical rankings when the same minimum acceptable return is chosen for the calculations.

C) give identical rankings when the assets have identical correlations with the market.

D) always provide identical rankings.

likaiba

 

The correct answer is C

The Treynor and Sharpe ratios will provide the same ranking for two assets that have identical correlations with the market. While Treynor uses beta to measure risk and Sharpe uses standard deviation, we can decompose the beta of a security into its correlation and standard deviation components such that equal correlations will yield identical calculations for the Sharpe and Treynor ratios.

28、Portfolios X and Y have had an equal average return over the most recent period. Compared to Portfolio Y, Portfolio X had higher total risk, but lower systematic risk. Given this information, which of the following statements is TRUE? Compared to Portfolio Y:

A) Portfolio X has a higher Sharpe ratio and a lower Treynor ratio.

B) Portfolio X has both a lower Sharpe ratio and a lower Treynor ratio.

C) Portfolio X has a lower Sharpe ratio and a higher Treynor ratio.

D) Portfolio X has both a higher Sharpe and a higher Treynor ratio.

likaiba

 

The correct answer is C

The two portfolios will have the same numerator for both the Sharpe and the Treynor ratio. Thus, the denominator of the two measures will determine their relative sizes. The Sharpe measure has the standard deviation or total risk in the denominator, thus the value will be lower for X. Since X has lower systematic risk, its denominator in the Treynor measure will be lower and the overall measure will be higher for X.

AIM 5: Discuss extensions to Jensen’s alpha.

An analyst has gathered the following information about the performance of an equity fund and the S& 500 index over the same time period.   Using Jensen’s Alpha to measure the risk/return performance of the Equity fund and the S& 500, which of the following conclusions is TRUE?  The:

                                                         Equity Fund            S& 500

                   Return                                  23%                     27%           

                   Standard Deviation                15%                     19%

                   Beta                                   1.09                    1.00

                   Risk-free rate is 3.50%

A)  Equity fund underperformed the S& 500 by 6.12%.

B)  S& 500 outperformed the equity fund by 3.24%.

C)  S& 500 underperformed the equity fund by 2.67%.

D)  Equity fund outperformed the S& 500 by 5.04%.

likaiba

 

The correct answer is A

Jensen’s Alpha: 0.23 – [0.035 + (0.27 – 0.035)1.09] = -0.0612 or -6.12%. The negative means it underperformed the S& 500.

AIM 6: Compute and interpret tracking error, the information ratio, and the Sortino ratio.

1、In the Sortino ratio, the excess return is divided by the:

A) standard deviation.

B) maximum drawdown.

C) standard deviation using only the returns below a minimum level

D) VAR.
