A highly risk-averse investor is considering adding one additional stock to a 3-stock portfolio, to form a 4-stock portfolio. The three stocks currently held all have b = 1.0, and they are perfectly positively correlated with the market. Potential new Stocks A and B both have expected returns of 15%, are in equilibrium, and are equally correlated with the market, with r = 0.75. However, Stock A's standard deviation of returns is 12% versus 8% for Stock B. Which stock should this investor add to his or her portfolio, or does the choice not matter?


A) Either A or B, i.e., the investor should be indifferent between the two.
B) Stock A.
C) Stock B.
D) Neither A nor B, as neither has a return sufficient to compensate for risk.
E) Add A, since its beta must be lower.

F) All of the above

Assume that to cool off the economy and decrease expectations for inflation, the Federal Reserve tightened the money supply, causing an increase in the risk-free rate, rRF. Investors also became concerned that the Fed's actions would lead to a recession, and that led to an increase in the market risk premium, (rM - rRF) . Under these conditions, with other things held constant, which of the following statements is most correct?


A) The required return on all stocks would increase by the same amount.
B) The required return on all stocks would increase, but the increase would be greatest for stocks with betas of less than 1.0.
C) Stocks' required returns would change, but so would expected returns, and the result would be no change in stocks' prices.
D) The prices of all stocks would decline, but the decline would be greatest for high-beta stocks.
E) The prices of all stocks would increase, but the increase would be greatest for high-beta stocks.

A) A large portfolio of randomly selected stocks will always have a standard deviation of returns that is less than the standard deviation of a portfolio with fewer stocks, regardless of how the stocks in the smaller portfolio are selected.
B) Diversifiable risk can be reduced by forming a large portfolio, but normally even highly-diversified portfolios are subject to market (or systematic) risk.
C) A large portfolio of randomly selected stocks will have a standard deviation of returns that is greater than the standard deviation of a 1-stock portfolio if that one stock has a beta less than 1.0.
D) A large portfolio of stocks whose betas are greater than 1.0 will have less market risk than a single stock with a beta = 0.8.

If the price of money (e.g., interest rates and equity capital costs) increases due to an increase in anticipated inflation, the risk-free rate will also increase. If there is no change in investors' risk aversion, then the market risk premium (rM − rRF) will remain constant. Also, if there is no change in stocks' betas, then the required rate of return on each stock as measured by the CAPM will increase by the same amount as the increase in expected inflation.

A) True
B) False

Assume that your uncle holds just one stock, East Coast Bank (ECB) , which he thinks has very little risk. You agree that the stock is relatively safe, but you want to demonstrate that his risk would be even lower if he were more diversified. You obtain the following returns data for West Coast Bank (WCB) . Both banks have had less variability than most other stocks over the past 5 years. Measured by the standard deviation of returns, by how much would your uncle's risk have been reduced if he had held a portfolio consisting of 60% in ECB and the remainder in WCB?
