Jane has a portfolio of 20 average stocks,and Dick has a portfolio of 2 average stocks.Assuming the market is in equilibrium,which of the following statements is CORRECT?


A) Jane's portfolio will have less diversifiable risk and also less market risk than Dick's portfolio.
B) The required return on Jane's portfolio will be lower than that on Dick's portfolio because Jane's portfolio will have less total risk.
C) Dick's portfolio will have more diversifiable risk, the same market risk, and thus more total risk than Jane's portfolio, but the required (and expected) returns will be the same on both portfolios.
D) If the two portfolios have the same beta, their required returns will be the same, but Jane's portfolio will have less market risk than Dick's.
E) The expected return on Jane's portfolio must be lower than the expected return on Dick's portfolio because Jane is more diversified.

Which of the following statements is CORRECT?


A) The slope of the SML is determined by the value of beta.
B) The SML shows the relationship between companies' required returns and their diversifiable risks. The slope and intercept of this line cannot be influenced by a firm's managers, but the position of the company on the line can be influenced by its managers.
C) Suppose you plotted the returns of a given stock against those of the market, and you found that the slope of the regression line was negative. The CAPM would indicate that the required rate of return on the stock should be less than the risk-free rate for a well-diversified investor, assuming investors expect the observed relationship to continue on into the future.
D) If investors become less risk averse, the slope of the Security Market Line will increase.
E) If a company increases its use of debt, this is likely to cause the slope of its SML to increase, indicating a higher required return on the stock.

Which of the following statements is CORRECT?


A) If the returns on two stocks are perfectly positively correlated and these stocks have identical standard deviations, an equally weighted portfolio of the two stocks will have a standard deviation that is less than that of the individual stocks.
B) A portfolio with a large number of randomly selected stocks would have more market risk than a single stock that has a beta of 0.5, assuming that the stock's beta was correctly calculated and is stable.
C) If a stock has a negative beta, its expected return must be negative.
D) A portfolio with a large number of randomly selected stocks would have less market risk than a single stock that has a beta of 0.5.
E) According to the CAPM, stocks with higher standard deviations of returns must also have higher expected returns.

Which of the following statements is CORRECT?


A) If a company's beta doubles, then its required rate of return will also double.
B) 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.

E) 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.

Someone who is risk averse has a general dislike for risk and a preference for certainty.If risk aversion exists in the market,then investors in general are willing to accept somewhat lower returns on less risky securities.Different investors have different degrees of risk aversion,and the end result is that investors with greater risk aversion tend to hold securities with lower risk (and therefore a lower expected return)than investors who have more tolerance for risk.
