D) 8.0%

11) Which of the following statements is false?

A) In exchange for bearing systematic risk, investors want to be compensated by earning a higher return.

B) A key step to measuring systematic risk is finding a portfolio that contains only unsystematic risk.

C) When evaluating the risk of an investment, an investor will care about its systematic risk, which cannot be eliminated through diversification.

D) To measure the systematic risk of a stock, we must determine how much of the variability of its return is due to systematic, market-wide risks versus diversifiable, firm specific risks.

12) Which of the following statements is false?

A) Beta differs from volatility.

B) The risk premium investors can earn by holding the market portfolio is the difference between the market portfolio’s expected return and the risk-free interest rate.

C) Stocks in cyclical industries, in which revenues tend to vary greatly over the business cycle, are likely to be more sensitive to systematic risk and have higher betas than stocks in less sensitive industries.

D) If we assume that the market portfolio (or the S&P 500) is efficient, then changes in the value of the market portfolio represent unsystematic shocks to the economy.
13) Which of the following statements is false?

A) Beta measures the sensitivity of a security to market wide risk factors.

B) Volatility measures total risk, while beta measures only systematic risk.

C) The beta is the expected percentage change in the excess return of the market portfolio for a 1% change in the excess return of a security.

D) Utilities tend to be stable and highly regulated, and thus are insensitive to fluctuations in the overall market.

14) Which of the following statements is false?

A) Because diversification improves with the number of stocks held in a portfolio an efficient portfolio should be a large portfolio containing many different stocks.

B) The beta of a security is the sensitivity of the security’s return to the return of the overall market.

C) An efficient portfolio cannot be diversified further, that is there is no way to reduce the risk of the portfolio without lowering its expected return.

D) We call a portfolio that contains only unsystematic risk an efficient portfolio.
