Consider an economy with two types of firms, S and I. S firms all move together. I firms move independently. For both types of firms, there is a 29% probability that the firm will have a 24% return and a 71% probability that the firm will have a -11% return. What is the volatility (standard deviation) of a portfolio that consists of an equal investment in: a. 40 firms of type S? b. 40 firms of type 1? a. What is the volatility (standard deviation) of a portfolio that consists of an equal investment in 40 firms of type S? Standard deviation is%. (Round to two decimal places.) b. What is the volatility (standard deviation) of a portfolio that consists of an equal investment in 40 firms of type I? Standard deviation is %. (Round to two decimal places.)

Suppose there are two independent economic factors, M₁ and M₂. The risk-free rate is 6%, and all stocks have independent firm- specific components with a standard deviation of 46%. Portfolios A and B are both well diversified. Portfolio A Beta on M₁ 1.5 2.0 Beta on My 2.1 -0.6 Required: What is the expected return-beta relationship in this economy? (Do not round intermediate calculations. Round your answers to 2 decimal places.) Expected return-beta relationship E(rp) = Expected Return (%) 36 14 45 60 Answer is not complete. Bp1 Bp2

Consider the following information on a portfolio of three stocks: State of Economy Probability of State of Economy Stock A Rate of Return Stock B Rate of Return Stock C Rate of Return Boom.13.02.32.50 Normal.55.10.22.20 Bust .32.16.21.35 If your portfolio is invested 40 percent each in A and B and 20 percent in C, what is the portfolio's expected return, the variance, and the standard deviation? Note: Do not round intermediate calculations. Round your variance answer to 5 decimal places, e.g., 16161. Enter your other answers as a percent rounded to 2 decimal places, e. g., 32.16. If the expected T-bill rate is 4.25 percent, what is the expected risk premium on the portfolio? Note: Do not round intermediate calculations and enter your answer as a percent rounded to 2 decimal places, e. g., 32.16.

Suppose Johnson & Johnson and the Walgreen Company have the expected returns and volatilities shown below, with a correlation of 22.2%. Johnson & Johnson Walgreen Company E [R] 7.2% 9.3% SD [R] 16.8% 20.4% For a portfolio that is equally invested in Johnson & Johnson's and Walgreen's stock, calculate: a. The expected return. b. The volatility (standard deviation). a. The expected return. The expected return of the portfolio is ☐ %. (Round to one decimal place.) b. The volatility (standard deviation). The volatility of the portfolio is %. (Round to one decimal place.)

Assume the market return is 14% with a standard deviation of 20%, and risk-free rate is 8%. The average annual returns for Managers D, E, and F are 13%, 17%, and 16% respectively. The corresponding standard deviations are 18%, 22%, and 23%. What are the Sharpe ratios for the market and managers?
