Ch7.C1. (Beta and required return) The riskless return is currently 6%, and Chicago Gear has estimated the contingent returns given here. a. Calculate the expected returns on the stock market and on Chicago Gear stock. b. What is Chicago Gear’s beta? c. What is Chicago Gear’s required return according to the CAPM? Realized Return State of the Market Probability that State Occurs Stock Market Chicago Gear Stagnant 0.20 (10%) (15%) Slow growth 0.35 10 15 Average growth 0.30 15 25 Rapid growth 0.15 25 35 Solution: a. Calculate the expected returns on the stock market and on Chicago Gear stock. Expected Returns on the market = ∑Probability * Realized return of market = - 0.20*10 + 0.35*10 + 0.30*15 + 0.15*25 = -2+3.5+4.5+3.75 = 9.75% Expected Returns on the Chicago Gear Stock = ∑Probability * Realized return of stock = -0.20*15 + 0.35*15 + 0.30*25 + 0.15*35 = -3.0 + 5.25 + 7.5 + 5.25 = 15.00% b. What is Chicago Gear’s beta?

Unformatted text preview: βcg = cov cg, m /σ 2 m = 180/121 = 1.49 You can apply the formula ∑Probability * (Expected Returns on the market - Realized return of market)*( Expected Returns on the Chicago Gear Stock- Realized return of stock) to calculate covariance between stock market and Chicago gear cov cg, m. which turns out to be 180. cov cg, m. = ∑Probability * (Expected Returns on the market - Realized return of market)*( Expected Returns on the Chicago Gear Stock- Realized return of stock) = 118.5 + 0.00 + 15.75 + 45.75 = 180.00 Variance of stock market can be calculated using ∑Probability * (Expected Returns on the market - Realized return of market) 2 which turns out to be 121 σ 2 m = ∑Probability * (Expected Returns on the market - Realized return of market) 2 = 78.01 + 0.02 + 8.27 + 34.88 = 121.19 c. What is Chicago Gear’s required return according to the CAPM? Chicago Gear’s required rate of return according to CAPM: Rcg = Rf + βcg(Rm-Rf) Required rate of return or Ks = r f + β (r m – r f) Rcg = .06 + 1.49 * (.0975-.06) = .1158 = 11.58%...

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
