Since the market return represents the expected return on an average stock, the market return reflects a certain amount of risk As a result, there exists a market risk premium, which is the amount over and above the risk-free rate, that is required to compensate stock investors for assuming an average amount of risk.

Which of the following statements is CORRECT?


A) Suppose the returns on two stocks are negatively correlated. One has a beta of 1.2 as determined in a regression analysis using data for the last 5 years, while the other has a beta of -0.6. The returns on the stock with the negative beta must have been negatively correlated with returns on most other stocks during that 5-year period.
B) Suppose you are managing a stock portfolio, and you have information that leads you to believe the stock market is likely to be very strong in the immediate future. That is, you are convinced that the market is about to rise sharply. You should sell your high-beta stocks and buy low-beta stocks in order to take advantage of the expected market move.
C) You think that investor sentiment is about to change, and investors are about to become more risk averse. This suggests that you should re-balance your portfolio to include more high-beta stocks.
D) If the market risk premium remains constant, but the risk-free rate declines, then the required returns on low-beta stocks will rise while those on high-beta stocks will decline.
E) Paid-in-Full Inc. is in the business of collecting past-due accounts for other companies, i.e., it is a collection agency. Paid-in-Full's revenues, profits, and stock price tend to rise during recessions.

Which of the following statements is CORRECT?


A) Other things held constant, if investors suddenly become convinced that there will be deflation in the economy, then the required returns on all stocks should increase.
B) If a company's beta were cut in half, then its required rate of return would also be halved.
C) If the risk-free rate rises by 0.5% but the market risk premium declines by that same amount, then the required rates of return on stocks with betas less than 1.0 will decline while returns on stocks with betas above 1.0 will increase.
D) If the risk-free rate rises by 0.5% but the market risk premium declines by that same amount, then the required rate of return on an average stock will remain unchanged, but required returns on stocks with betas less than 1.0 will rise.
E) If a company's beta doubles, then its required rate of return will also double.
