Consider the following simplified APT model:
Factor Expected Risk Premium
Market 6.4%
Interest Rate -0.6%
Yield Spread 5.1%
Factor Risk Exposures
Market Interest Rate Yield Spread Stock Stock (b1) (b2) (b3)
P 1.0 -2.0 -0.2
P2 1.2 0 0.3
P3 0.3 0.5 1.0
a) Calculate the expected return for the above stocks. Assume risk free rate is 5%. Consider a portfolio with equal investments in stocks P, P2 , and P3 b) What are the factor risk exposures for the portfolio?
c) What is the portfolio’s expected return?

- You are given the following information concerning three portfolios, the market portfolio, and the risk- free asset: Portfolio X Y Z Market Risk-free Rp 14.5% R-squared 13.5 9.1 10.7 5.4 op 36% 31 21 26 0 6p 1.60 1.30 .80 1.00 0 Assume that the correlation of returns on Portfolio Y to returns on the market is 72. What percentage of Portfolio Y's return is driven by the market? (Enter your answer as a decimal not a percentage. Round your answer to 4 decimal places.)arrow_forwardAccording to CAPM, the expected rate of return of a portfolio with a beta of 1.0 and an alpha of 0 is:a. Between rM and rf .b. The risk-free rate, rf .c. β(rM − rf).d. The expected return on the market, rM.arrow_forwardThe risk-free rate is 5.6%, the market risk premium is 8.5%, and the stock’s beta is 2.27. What is the required rate of return on the stock, E(Ri)? Use the CAPM equation.arrow_forward
- b) Suppose that you observe the following information in Table 2 for stocks A and B: Table 2 Expected Return (%) 11% Stock Beta A 0.8 В 14% 1.5 The risk-free rate of return is 6% and the expected rate of return on the market index is 12%. Using the Single-Index Model, calculate the alpha of both stocks. Show your calculations. Explain what the alpha of the single-factor model represents and interpret your results.arrow_forwardWhich of the following statement(s) is(are) true? 1) The real rate of interest is determined by the supply and demand for funds. II) The real rate of interest is determined by the expected rate of inflation. III) The real rate of interest is unaffected by actions of the Fed. IV) The real rate of interest is equal to the nominal interest rate plus the expected rate of inflation. III and IV only. I only. OII and III only. O, II, III, and IV only. OI and III only.arrow_forwardA stock portfolio has the following returns under the market conditions listed below.

- Suppose that there are many stocks in the security market and that the characteristics of stocks A and B are given as follows: Stock A B Expected Return 10% Standard Deviation 5% 9 18 Correlation = -1 Risk-free rate Suppose that it is possible to borrow at the risk-free rate, rf. What must be the value of the risk-free rate? (Hint: Think about constructing a risk-free portfolio from stocks A and B.) Note: Do not round intermediate calculations.
