Assume that there are two factors that price assets. Interest rate rf = 4%. You have thefollowing information about two well-diversified arbitrage-free risky portfolios. (a) Calculate the risk premium of the two risk factors. (b) There is a third well-diversified portfolio with β1 = 1.1 and β2 = 0.9. What is thisportfolio’s arbitrage free expected return? (c) Suppose the forecasted return of the portfolio in the question (b) is 13.5%. Show how youcould construct an arbitrage portfolio.
consider the following data for a single factor model economy. all portfolios are well diversified. suppose portfolio p has an expected return of 19% and beta of 2.0. portfolio m has an expected retrun of 12% and beta of 1.0. assume that the risk free rate is 7% and that arbitrage opportunities exist. what is the portfolio p's alpha?
Assume that both portfolios A and B are well diversified, that E(rA) = 12%, and E(rB) = 9%. If the economy has only one factor, and βA = 1.2, whereas βB = .8, what must be the risk-free rate?
Suppose that you use Arbitrage Pricing Theory (APT) to evaluate well-diversified portfolios. The three factor portfolios used in an APT model, portfolios 1, 2, and 3, have expected returns E(r1) = 5%, E(r2) = 3%, and E(r3) = 8%. Suppose further that the risk-free rate (λ0) is 2%. Calculate the total return on a well- diversified portfolio with its beta on the first factor, βA1 = 1.1, beta on the second factor, βA2 = .9, and beta on the third factor, βA3 = 1.2.
Consider the multifactor model APT with three factors. Portfolio A has a beta of 0.8 on factor 1, a beta of 1.1 on factor 2, and a beta of 1.25 on factor 3. The risk premiums on the factor 1, factor 2, and factor 3 are 3%, 5%, and 2%, respectively. The risk-free rate of return is 3%. The expected return on portfolio A is __________ if no arbitrage opportunities exist. A. 23.0% B. 16.5% C. 13.4% D. 13.5%
Suppose that there are two independent economic factors, F1 and F2. The risk-free rate is 6%. The following are well-diversified portfolios: Portfolio Beta on F1 Beta on F2 Expected Return A 1.5 2.0 31% B 2.2 -0.2 27% [i]. What is the risk premium for F1?
Consider the following data for a one-factor economy. All portfolios are assumed to be well diversified. Portfolio. A. F Expected return 12% 6% Beta. 1.2 0.0 Suppose that another portfolio, portfolio E, is well diversified with a beta of 0.6 and expected return of 8%. Would an arbitrage opportunity exist? If so, what would be the arbitrage strategy? (Note: show what the percentage profit from arbitrage will be)
Consider an economy where Capital Asset Pricing Model holds. In this economy, stocks A and B have the following characteristics: • Stock A has and expected return of 22% and a beta of 2. • Stock B has an expected return of 15% and a beta of 0.8. The standard deviation of the market portfolio’s return is 18%. (a) Assuming that stocks A and B are correctly priced according to the CAPM, compute the risk-free rate and the market risk premium. (b) Draw the security market line, showing the positions of stocks A and B, as well as the risk-free rate and the market portfolio on the plot. You are not required to draw the security market line to scale. (c) Consider stock C that has an expected return of 30%, a beta of 2.3, and a standard deviation of returns of 20%. According to the CAPM, calculated in part (a) above, is stock C overpriced, underpriced, or correctly priced? What would you recommend to investors? (d) Briefly explain the definition of market portfolio in a CAPM economy
The risk-free rate is currently 3.3%, and the market return is 14.8%. Assume you are considering the following investments: Investment Beta A 1.54 B 1.16 C 0.51 D 0.11 E 2.14 . a. Which investment is most risky? Least risky? b. Use the capital asset pricing model (CAPM) to find the required return on each of the investments. c. Find the security market line (SML), using your findings in part b. d. On the basis of your findings in part c, what relationship exists between risk and return? Explain.
Consider the multifactor APT. There are two independent economic factors, F1 and F2. The risk-free rate of return is 3%. The following information is available about two well-diversified portfolios: Portfolio B on F1 B on F2 Expected Return 0.5 1.5 11.5% 2.0 -1.0 9.0% Assuming no arbitrage opportunities exist, the risk premium on the factor portfolios F1 and F2 should be: A B O a. 12.14%, 9.29% O b. 9.29%, 12.14% O c. 5%,4% O d. 4%,5%
Assume both portfolios A and B are well diversified, that E(rA) = 12.6% and E(rB) = 13.6%. If the economy has only one factor, and βA = 1 while βB = 1.2, what must be the risk-free rate? (Do not round intermediate calculations. Round your answer to 1 decimal place.)
The risky portfolio expected return and standard deviation is 14% and 20%, respectively. The risk free rate is 5%. The risk aversion coefficient A is 2.5 and 4 for Mary and Kim, respectively. Answer the following questions: A. Who is more risk averse? B. What is the capital allocation y to the risky portfolio for each investor? C. Suppose investors have the following utility function: U = E(R) - ¹2 Ao² Calculate the Utility level for each investor's optimal complete portfolio.
