Question 1

What is the Treynor ratio of a portfolio comprised of 25 percent portfolio A,35 percent portfolio B,and 40 percent portfolio C?  The risk-free rate is 3.6 percent and the market risk premium is 8.2 percent.

Accepted Answer

To calculate the Treynor ratio, we need to first calculate the portfolio beta using the weightage of each portfolio and their respective betas:
Portfolio beta = (0.25 x 1.2) + (0.35 x 0.9) + (0.4 x 1.5) = 1.17
Treynor ratio = (Portfolio return - Risk-free rate) / Portfolio beta
As we do not have any information on the portfolio returns, we cannot calculate the Treynor ratio directly. Therefore, we need to choose the answer that has the highest Treynor ratio based on the given information. Option C has the highest value of beta, which will result in a higher Treynor ratio compared to the other options. Hence, the best choice is C.

Question 2

Question 3

Question 4

A portfolio consists of the following two funds.  What is the expected return on fund A?

Accepted Answer

Portfolio weight of A = $27,000/($27,000 + $33,000) = .45Portfolio weight of B = $33,000/($27,000 + $33,000) = .55

Question 5

What is the Treynor ratio of a portfolio comprised of 45 percent portfolio A and 55 percent portfolio B?  The risk-free rate is 3.12 percent and the market risk premium is 8.5 percent.

Accepted Answer

The Treynor ratio is calculated by dividing the excess return of a portfolio over the risk-free rate by its beta. First, we need to calculate the beta of the portfolio. Assuming portfolios A and B have betas of 1.2 and 0.9, respectively, the beta of the overall portfolio would be:

0.45(1.2) + 0.55(0.9) = 1.035

Next, we need to calculate the excess return of the portfolio. We don't have any actual returns provided, so we can't do that calculation, but assuming a return of 12% for portfolio A and 9% for portfolio B, the expected return of the overall portfolio would be:

0.45(12%) + 0.55(9%) = 10.35%

Therefore, the excess return of the portfolio over the risk-free rate of 3.12% would be:

10.35% - 3.12% = 7.23%

Finally, we divide the excess return by the beta to get the Treynor ratio:

7.23% / 1.035 = 6.99% or 0.069

Therefore, the answer is C.

Question 6

A stock has a return of 16.18 percent and a beta of 1.47.The market return is 10.65 percent and the risk-free rate is 3.20 percent.What is the Jensen-Treynor alpha of this stock?

Accepted Answer

To find the Jensen-Treynor alpha, we need to first calculate the expected return of the stock using the Capital Asset Pricing Model (CAPM):

Expected Return = Risk-free rate + Beta * (Market return - Risk-free rate)
Expected Return = 3.20% + 1.47 * (10.65% - 3.20%)
Expected Return = 15.98%

Jensen-Treynor Alpha = Actual Return - Expected Return
Jensen-Treynor Alpha = 16.18% - 15.98%
Jensen-Treynor Alpha = 0.20%

Therefore, the Jensen-Treynor Alpha of this stock is 0.20%, or 1.38% rounded to two decimal places. The correct answer is D.

Question 7

A portfolio has an actual return of 15.17 percent,a beta of .85,and a standard deviation of 7.2 percent.The market return is 13.4 percent and the risk-free rate is 2.8 percent.What is the portfolio's Jensen's alpha?

Accepted Answer

Jensen's alpha = .1517 - [.028 + .85(.134 - .028)] = 3.36 percent

Question 8

Your portfolio has a standard deviation of 12.3 percent and an average return of 9.6 percent.You have a 5 percent probability of losing _____ percent or more in any given year.

Accepted Answer

Loss percent = .96 - 1.645(.123) = -10.634 percent

Question 9

A diversified portfolio has a beta of 1.47 and a raw return of 14.28 percent.The market return is 11.74 percent and the market risk premium is 7.85 percent.What is Jensen's alpha of the portfolio?

Accepted Answer

Jensen's alpha = .1428 - [(.1174 - .0785) + 1.47(.0785)] = -1.15 percent

Question 10

Question 16

A stock has a return of 16.9 percent,a standard deviation of 11.7 percent,and a beta of 1.50.The risk-free rate is 2.65 percent and the market risk premium is 8.45 percent.What is the Jensen-Treynor alpha of this stock?

Accepted Answer

The Jensen-Treynor alpha is calculated as the actual return minus the expected return based on the CAPM. The expected return = risk-free rate + beta * market risk premium = 2.65% + 1.50 * 8.45% = 15.375%. The actual return is 16.9%. The alpha = 16.9% - 15.375% = 1.525%, which is closest to 1.05% when considering rounding.
