The correct answer is A

Jensen’s alpha measures the return above the required rate of return based on the fund’s systematic risk. Said differently, Jensen’s alpha is the amount of return earned by the fund over and above the return predicted for the fund based on the capital asset pricing model, given the fund’s systematic risk.

17、Which of the following statements regarding the Sharpe ratio is most accurate? The Sharpe ratio measures:

A) excess return per unit of risk.

B) total return per unit of risk.

C) dispersion relative to the mean.

D) peakedness of a return distrubtion.

likaiba

 

The correct answer is A

The Sharpe ratio measures excess return per unit of risk. Remember that the numerator of the Sharpe ratio is (portfolio return ? risk free rate), hence the importance of excess return. Note that dispersion relative to the mean is the definition of the coefficient of variation, and the peakedness of a return distribution is measured by kurtosis.

18、Johnson Inc. manages a growth portfolio of equity securities that has had a mean monthly return of 1.4% and a standard deviation of returns of 10.8%. Smith Inc. manages a blended equity and fixed income portfolio that has had a mean monthly return of 1.2% and a standard deviation of returns of 6.8%. The mean monthly return on Treasury bills has been 0.3%. Which of the following statements is most accurate?

The correct answer is D

The Sharpe ratio for the Johnson portfolio is (1.4 - 0.3)/10.8 = 0.1019.

The Sharpe ratio for the Smith portfolio is (1.2 - 0.3)/6.8 = 0.1324.

The Smith portfolio has the higher Sharpe ratio, or greater excess return per unit of risk.
