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.

Multiple Choice
A) If a company with a high beta merges with a low-beta company, the best estimate of the new merged company's beta is 1.0.
B) Logically, it is easier to estimate the betas associated with capital budgeting projects than the betas associated with stocks, especially if the projects are closely associated with research and development activities.
C) The beta of an "average stock," which is also "the market beta," can change over time, sometimes drastically.
D) If a newly issued stock does not have a past history that can be used for calculating beta, then we should always estimate that its beta will turn out to be 1.0. This is especially true if the company finances with more debt than the average firm.
E) During a period when a company is undergoing a change such as increasing its use of leverage or taking on riskier projects, the calculated historical beta may be drastically different from the beta that will exist in the future.

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.
E) If you add enough randomly selected stocks to a portfolio, you can completely eliminate all of the market risk from the portfolio.

A) A stock's beta is less relevant as a measure of risk to an investor with a well-diversified portfolio than to an investor who holds only that one stock.
B) If an investor buys enough stocks, he or she can, through diversification, eliminate all of the diversifiable risk inherent in owning stocks. Therefore, if a portfolio contained all publicly traded stocks, it would be essentially riskless.
C) The required return on a firm's common stock is, in theory, determined solely by its market risk. If the market risk is known, and if that risk is expected to remain constant, then no other information is required to specify the firm's required return.
D) Portfolio diversification reduces the variability of returns (as measured by the standard deviation) of each individual stock held in a portfolio.
E) A security's beta measures its non-diversifiable, or market, risk relative to that of an average stock.

Multiple Choice
A) If you invest $50,000 in Stock X and $50,000 in Stock Y, your 2-stock portfolio would have a beta significantly lower than 1.0, provided the returns on the two stocks are not perfectly correlated.
B) Stock Y's realized return during the coming year will be higher than Stock X's return.
C) If the expected rate of inflation increases but the market risk premium is unchanged, the required returns on the two stocks should increase by the same amount.
D) Stock Y's return has a higher standard deviation than Stock X.
E) If the market risk premium declines, but the risk-free rate is unchanged, Stock X will have a larger decline in its required return than will Stock Y.

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.
