Final Exam 407

If the beta of the market index is 1 and the standard deviation of the market index increases from 12% to 18%, what is the new beta of the market index?

1

Research has revealed that regardless of what the current estimate of a firm's beta is, beta will tend to move closer to ______ over time.

1

The market portfolio has a beta of _________.

1

Using the index model, the alpha of a stock is 3%, the beta is 1.1, and the market return is 10%. What is the residual given an actual return of 15%?

1% Residual = 15 - (3 + 1.1 × 10) = 1%

You have a $50,000 portfolio consisting of Intel, GE, and Con Edison. You put $20,000 in Intel, $12,000 in GE, and the rest in Con Edison. Intel, GE, and Con Edison have betas of 1.3, 1, and .8, respectively. What is your portfolio beta?

1.048 (20/50)*(1.3) +(12/50)*1.0+(18/50)*(.8) = 1.048

Consider the CAPM. The risk-free rate is 5%, and the expected return on the market is 15%. What is the beta on a stock with an expected return of 17%?

1.2 17% = 5% + [15% - 5%]βs; βs = 1.2

You invest $600 in security A with a beta of 1.5 and $400 in security B with a beta of .90. The beta of this portfolio is _________.

1.26 Beta= (600/1000)*(1.5) + (400/1000) * (.9) = 1.26

What is the beta for a portfolio with an expected return of 12.5%?

1.5 Since rf = 5% and E(rM) = 10%, from the CAPM we know that 12.5% = 5% + beta(10% - 5%), and therefore beta = 1.5.

Consider the capital asset pricing model. The market degree of risk aversion, A, is 3. The variance of return on the market portfolio is .0225. If the risk-free rate of return is 4%, the expected return on the market portfolio is _________.

10.75% E(rm)= .04 + 3(.0225) = 10.75

What is the expected return on a stock with a beta of .8, given a risk-free rate of 3.5% and an expected market return of 15.5%?

13.1% Expected return = 3.5 + (.8)(15.5 - 3.5) = 13.1%

According to the CAPM, what is the expected market return given an expected return on a security of 15.8%, a stock beta of 1.2, and a risk-free interest rate of 5%?

14% 15.8 = 5 + 1.2 × (MRP); MRP = 9%; Expected market return = 5 + 9 = 14%

The risk-free rate and the expected market rate of return are 6% and 16%, respectively. According to the capital asset pricing model, the expected rate of return on security X with a beta of 1.2 is equal to _________.

18% E(r) = .06 + 1.2 * ( .16 - .06 ) = .18 ALPHA A = .10 - [.05 + 1.20 * (.09 - .05)] = .002 ALPHA B = .14 - [.05+ 1.80 * (.09 - .05) ] = .018

The variance of the return on the market portfolio is .04 and the expected return on the market portfolio is 20%. If the risk-free rate of return is 10%, the market degree of risk aversion, A, is _________.

2.5 A= (.20 - .10)/.04=2.5

Consider the CAPM. The risk-free rate is 6%, and the expected return on the market is 18%. What is the expected return on a stock with a beta of 1.3?

21.6% E[rs] = 6% + [18% - 6%](1.3) = 21.6%

What is the expected return for a portfolio with a beta of .5?

7.5% Rp = Rf + .5(Rm + Rf) 5% + .5(10% - 5%) = 7.5%

According to the CAPM, what is the market risk premium given an expected return on a security of 13.6%, a stock beta of 1.2, and a risk-free interest rate of 4%?

8% 13.6 = 4 + 1.2 × (MRP); MRP = 8%

Consider the CAPM. The expected return on the market is 18%. The expected return on a stock with a beta of 1.2 is 20%. What is the risk-free rate?

8% 20% = rF + (18 - rF)(1.2); rF = 8%

If you want to make sure your active strategy adds value, how much can you spend on security analysis?

B. $6,000,000 (.001)($6 billion) = $6,000,000

Consider two stocks, A and B. Stock A has an expected return of 10% and a beta of 1.2. Stock B has an expected return of 14% and a beta of 1.8. The expected market rate of return is 9% and the risk-free rate is 5%. Security __________ would be considered the better buy because _________.

B; it offers an expected excess return of 1.8% ALPHA A = .10 - [.05 + 1.20 * (.09 - .05)] = .002 ALPHA B = .14 - [.05+ 1.80 * (.09 - .05) ] = .018
