Chapter 10, Problem 23P
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 60% probability that the firms will have a 15% return and a 40% probability that the firms will have a –10% return. What is the volatility (standard deviation) of a portfolio that consists of an equal investment in 20 firms of (a) type S, and (b) type 1?

For both types of firms, there is a 60% probability that the firm will have a 15% return and a 40% probability that the firm will have a −10% return. What is the volatility (standard deviation) of a portfolio that consists of an equal investment in:
a. 20 firms of type S?
b. 20 firms of type I?
Consider an economy with two types of firms, S and I. S firms always move together, but I firms move independently of each other. For both types of firm there is a 60% probability that the firm will have a 20% return and a 40% probability that the firm will have a -30% return.
The standard deviation for the return on a portfolio of 20 type S firms is closest to:
24%
23%
15%
35%
Consider an economy with two types of firms, S and I. S firms always move together, but I firms move independently. For both types of firms, there is a 60% probability that the firm will have a 21% return. Otherwise, the firm will have a -20% return. The standard deviation for the return on a portfolio of 20 type S firms is closest to:

For both types of firm there is a 70% probability that the firm will have a 20% return and a 30% probability that the firm will have a -30% return. The standard deviation for the return on a portfolio of 20 type S firms is closest to: Question content area bottom Part 1 A. 23.0%. B. 5.10%. C. 5.25%. D. 15.0%.arrow_forwardSuppose that there are two independent economic factors, F1 and F2. The risk-free rate is 10%, and all stocks have independent firm-specific components with a standard deviation of 40%. Portfolios A and B are both well-diversified with the following properties: Portfolio Beta on F1 Beta on F2 Expected Return A 1.6 2.0 30 % B 2.5 –0.20 25 % What is the expected return-beta relationship in this economy? Calculate the risk-free rate, rf, and the factor risk premiums, RP1 and RP2, to complete the equation below. (Do not round intermediate calculations. Round your answers to two decimal places.)E(rP) = rf + (βP1 × RP1) + (βP2 × RP2)arrow_forwardA manager believes his firm will earn a 14 percent return next year. His firm has a beta of 1.5, the expected return on the market is 12 percent, and the risk-free rate is 4 percent. Compute the return the firm should earn given its level of risk.arrow_forward
- Consider a CAPM economy. The risk free rate (rf ) is 4% and the expected market return (rM )is 10%. (a) Stock 1: β = 0.90. Compute the expected return of stock 1. (b) Stock 2: β = 1.1. Compute the expected return of stock 2. (c) Portfolio 1: The proportions invested in stock 1, stock 2, and risk free asset are 30%, 30%,and 40%, respectively. Compute the beta and expected return of portfolio 1. (d) Portfolio 2: The proportions invested in stock 1, stock 2, and risk free asset are 50%, 60%,and -10%, respectively. Compute the beta and expected return of portfolio 2.arrow_forwardA financial manager believes that her firm will earn a 15% return next year. This firm has a beta of 1.8, and the expected return on the market is 8% while the risk-free rate is 2%. First, compute the return this firm should earn given its level of risk. Second, determine whether this firm’s stock is overvalued or undervalued given what the manager thinks this company will earn next year.arrow_forwardAssume the return on a market index represents the common factor and all stocks in the economy have a beta of 1. Firm-specific returns all have a standard deviation of 40%.Suppose an analyst studies 20 stocks and finds that one-half have an alpha of 2.3%, and one-half have an alpha of –2.3%. The analyst then buys $1.2 million of an equally weighted portfolio of the positive-alpha stocks and sells short $1.2 million of an equally weighted portfolio of the negative-alpha stocks. Required: a. What is the expected profit (in dollars), and what is the standard deviation of the analyst’s profit? (Enter your answers in dollars not in millions.
