If the expected rate of return for a particular stock,as seen by the marginal investor,exceeds its required rate of return,we should soon observe an increase in demand for the stock,and the price will likely increase until a price is established that equates the expected return with the required return.The sooner this equilibrium is reached,the more efficient the market is judged to be.

B) False

A) When company-specific risk has been diversified away, the inherent risk that remains is market risk, which is constant for all stocks in the market.
B) Portfolio diversification reduces the variability of returns on an individual stock.
C) Risk refers to the chance that some unfavourable event will occur, and a probability distribution is completely described by a listing of the likelihoods of unfavourable events.
D) The SML relates a stock's required return to its market risk. The slope and intercept of this line cannot be controlled by the firms' managers, but managers can influence their firms' positions on the line.

Assume that two investors each hold a portfolio,and that portfolio is their only asset.Investor A's portfolio has a beta of minus 2.0,while Investor B's portfolio has a beta of plus 2.0.Assuming that the unsystematic risks of the stocks in the two portfolios are the same,then the two investors face the same amount of risk.However,the holders of either portfolio could lower their risks,and by exactly the same amount,by adding some "normal" stocks with beta = 1.0.

Nile Foods' stock has a beta of 1.4,while Elba Eateries' stock has a beta of 0.7.Assume that the risk-free rate,rRF,is 5.5% and the market risk premium,(rM - rRF) ,equals 4%.Which of the following statements is correct?


A) If the risk-free rate increases but the market risk premium remains unchanged, the required return will increase for both stocks but the increase will be larger for Nile since it has a higher beta.
B) If the market risk premium increases but the risk-free rate remains unchanged, Nile's required return will increase because it has a beta greater than 1.0 but Elba's will decline because it has a beta less than 1.0.
C) Since Nile's beta is twice that of Elba's, its required rate of return will also be twice that of Elba's.
D) If the risk-free rate increases while the market risk premium remains constant, then the required return on an average stock will increase.
