Which of the following statements is CORRECT?


A) If you add enough randomly selected stocks to a portfolio,you can completely eliminate all of the market risk from the portfolio.
B) If you were restricted to investing in publicly traded common stocks,yet you wanted to minimize the riskiness of your portfolio as measured by its beta,then according to the CAPM theory you should invest an equal amount of money in each stock in the market.That is,if there were 10,000 traded stocks in the world,the least risky possible portfolio would include some shares of each one.
C) If you formed a portfolio that consisted of all stocks with betas less than 1.0,which is about half of all stocks,the portfolio would itself have a beta coefficient that is equal to the weighted average beta of the stocks in the portfolio,and that portfolio would have less risk than a portfolio that consisted of all stocks in the market.
D) Market risk can be eliminated by forming a large portfolio,and if some Treasury bonds are held in the portfolio,the portfolio can be made to be completely riskless.
E) A portfolio that consists of all stocks in the market would have a required return that is equal to the riskless rate.

F) All of the above
G) C) and D)

Your portfolio consists of $50,000 invested in Stock X and $50,000 invested in Stock Y.Both stocks have an expected return of 15%,betas of 1.6,and standard deviations of 30%.The returns of the two stocks are independent,so the correlation coefficient between them,rXY,is zero.Which of the following statements best describes the characteristics of your 2-stock portfolio?


A) Your portfolio has a standard deviation of 30%,and its expected return is 15%.
B) Your portfolio has a standard deviation less than 30%,and its beta is greater than 1.6.
C) Your portfolio has a beta equal to 1.6,and its expected return is 15%.
D) Your portfolio has a beta greater than 1.6,and its expected return is greater than 15%.
E) Your portfolio has a standard deviation greater than 30% and a beta equal to 1.6.

Nile Food's 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 required return 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.
E) If the market risk premium decreases but the risk-free rate remains unchanged,Nile's required return will decrease because it has a beta greater than 1.0 and Elba's will also decrease,but by more than Nile's because it has a beta less than 1.0.

Over the past 89 years,we have observed that investments with the highest average annual returns also tend to have the highest standard deviations of annual returns.This observation supports the notion that there is a positive correlation between risk and return.Which of the following answers correctly ranks investments from highest to lowest risk (and return) ,where the security with the highest risk is shown first,the one with the lowest risk last?


A) Small-company stocks,long-term corporate bonds,large-company stocks,long-term government bonds,U.S.Treasury bills.

Which of the following statements is CORRECT?


A) If Mutual Fund A held equal amounts of 100 stocks,each of which had a beta of 1.0,and Mutual Fund B held equal amounts of 10 stocks with betas of 1.0,then the two mutual funds would both have betas of 1.0.Thus,they would be equally risky from an investor's standpoint,assuming the investor's only asset is one or the other of the mutual funds.
B) If investors become more risk averse but rRF does not change,then the required rate of return on high-beta stocks will rise and the required return on low-beta stocks will decline,but the required return on an average-risk stock will not change.
C) An investor who holds just one stock will generally be exposed to more risk than an investor who holds a portfolio of stocks,assuming the stocks are all equally risky.Since the holder of the 1-stock portfolio is exposed to more risk,he or she can expect to earn a higher rate of return to compensate for the greater risk.
D) There is no reason to think that the slope of the yield curve would have any effect on the slope of the SML.
E) Assume that the required rate of return on the market,rM,is given and fixed at 10%.If the yield curve were upward sloping,then the Security Market Line (SML) would have a steeper slope if 1-year Treasury securities were used as the risk-free rate than if 30-year Treasury bonds were used for rRF.

One key conclusion of the Capital Asset Pricing Model is that the value of an asset should be measured by considering both the risk and the expected return of the asset,assuming that the asset is held in a well-diversified portfolio.The risk of the asset held in isolation is not relevant under the CAPM.

A) The fact that a security or project may not have a past history that can be used as the basis for calculating beta.

D) Sometimes the past data used to calculate beta do not reflect the likely risk of the firm for the future because conditions have changed.
