already knew about most of the news item

The _____coefficient is the amount of systematic risk present in a particular risky asset relative to that in an average asset.

beta

The expected return on the market will increase if the risk-free rate _________ or if the market risk premium _____.

increases; increases Reason: The expected return on the market will increase if the risk-free rate increases or if the market risk premium increases. It is an increasing function of both.

not change

Consider the following information: State of Economy Probability of State of Economy Portfolio Return if State Recession .10 −.17 Normal .60 .08 Boom .30 .27

11.20%

The risk free rate is 4%, and the required return on the market is 12%. What is the required return on a portfolio consisting of 40% of an asset with a beta of 1.5, and the rest invested in an asset with an average amount of systematic risk?

13.6% How did we get it? There's 2 assets, an asset of 40%, and an asset of 60% with an average amount of systematic risk. (100 - 40 = 60) Your equation will be divided into two, where 60% asset will have a beta of 1 (average systematic risk), and a return on market of 12%, because an average systematic risk will be equal to the return on market. The 40% will have to be found with risk premium and risk free rate. 60% Asset: .60*.12= .072 = 7.2% 40% Asset: Find risk premium by subtracting risk free rate from return on market, .12-.04 = .08 Multiply 8% risk premium by 1.5 beta .08 * 1.5 = .12 Add the risk free rate back .12 + .04 = .16 Multiply by 40% to find the return of the 40% asset .064 = 6.4% Add both asset returns to get compounded return .072 +.064 = .136 = 13.6%

Consider an asset with a beta of 1.2, a risk-free rate of 5%, and a market return of 13%. What is the expected return on the asset?

14.6% You have to deduct the risk-free rate of 5% from the market return of 13% to get the market risk premium before doing the equation 13-5 = 8% 1.2 * 8% = .09600 Add back risk free rate .09600 + .05 = .146 =14.6%

A firm faces many risks. Which of the following are examples of unsystematic risks faced by a firm?

Assets A and B each have an expected return of 10 percent. Asset A has a standard deviation of 12 percent while Asset B has a standard deviation of 13 percent. Which asset would a rational investor choose?

Asset A Reason: A is better as it offers the same return at a lower level of risk.

How can a positive relationship between the expected return on a security and its beta be justified?

Because the difference between the return on the market and the risk-free rate is likely to be positive

According to the CAPM, which of the following events would affect the return on a risky asset?

Federal reserve actions that affect the economy A change in the yield on T-bills A strengthening of the country's currency Reason: According to the CAPM, a security's return is a function of the pure time value of money (risk-free rate), the reward for bearing systematic risk (risk premium on the market), and the amount of systematic risk present in the security (measured by beta). A fire in the company's plant is not likely to change any of these things.
