The correlation between Stocks A and B is computed as the: A) covariance between A and B divided by the standard deviation of A times the standard deviation of B. B) standard deviation of A divided by the standard deviation of B. C) standard deviation of AB divided by the covariance between A and B. D) variance of A plus the variance of B divided by the covariance of AB. E) square root of the covariance of AB.

covariance between A and B divided by the standard deviation of A times the standard deviation of B.

The beta of a security is calculated by dividing the: A) covariance of the security return with the market return by the variance of the market. B) correlation of the security return with the market return by the variance of the market. C) variance of the market by the covariance of the security return with the market return. D) variance of the market return by the correlation of the security return with the market return. E) covariance of the security return with the market return by the correlation of the security and market returns.

covariance of the security return with the market return by the variance of the market.

The variance of a portfolio comprised of many securities is primarily dependent upon the: A) variances of the securities held within the portfolio. B) beta of the portfolio. C) portfolio's correlation with the market. D) covariance between the overall portfolio and the market. E) covariances between the individual securities.

covariances between the individual securities.

The primary purpose of portfolio diversification is to: A) increase returns and risks. B) eliminate all risks. C) eliminate asset-specific risk. D) eliminate systematic risk. E) lower both returns and risks.

eliminate asset-specific risk.

You are considering purchasing Stock S. This stock has an expected return of 12 percent if the economy booms, 8 percent if the economy is normal, and 3 percent if the economy goes into a recessionary period. The overall expected rate of return on this stock will: A) be equal to one-half of 8 percent if there is a 50 percent chance of an economic boom. B) vary inversely with the growth of the economy. C) increase as the probability of a recession increases. D) be independent of the probability of each economic state occurring. E) increase as the probability of a boom economy increases.

increase as the probability of a boom economy increases.

The expected return on a portfolio: A) can be greater than the expected return on the best performing security in the portfolio. B) can be less than the expected return on the worst performing security in the portfolio. C) is independent of the performance of the overall economy. D) is limited by the returns on the individual securities within the portfolio. E) is an arithmetic average of the returns of the individual securities when the weights of those securities are unequal.

is limited by the returns on the individual securities within the portfolio.

The slope of the security market line is the: A) reward-to-risk ratio. B) portfolio weight. C) beta coefficient. D) risk-free interest rate. E) market risk premium.

market risk premium.

If a stock portfolio is well diversified, then the portfolio variance: A) will equal the variance of the most volatile stock in the portfolio. B) may be less than the variance of the least risky stock in the portfolio. C) must be equal to or greater than the variance of the least risky stock in the portfolio. D) will be a weighted average of the variances of the individual securities in the portfolio. E) will be an arithmetic average of the variances of the individual securities in the portfolio.

may be less than the variance of the least risky stock in the portfolio.

A dominant portfolio within an opportunity set that has the lowest possible level of risk is referred to as the: A) efficient frontier. B) minimum variance portfolio. C) upper tail of the efficient set. D) tangency portfolio. E) optimal covariance portfolio.

minimum variance portfolio.

You have a portfolio comprised of two risky securities. This combination produces no diversification benefit. The lack of diversification benefits indicates the returns on the two securities: A) are too low for their level of risk. B) move perfectly opposite of one another. C) are too large to offset. D) move perfectly in sync with one another. E) are completely unrelated to one another.

move perfectly in sync with one another.

The principle of diversification tells us that: A) concentrating an investment in two or three large stocks will eliminate all your risk. B) concentrating an investment in three companies all within the same industry will greatly reduce your overall risk. C) spreading an investment across five diverse companies will not lower your overall risk. D) spreading an investment across many diverse assets will eliminate all the risk. E) spreading an investment across many diverse assets will eliminate idiosyncratic risk.

spreading an investment across many diverse assets will eliminate idiosyncratic risk.

The measure of beta associates most closely with: A) idiosyncratic risk. B) the risk-free return. C) systematic risk. D) unexpected risk. E) unsystematic risk.

systematic risk.

An efficient set of portfolios is comprised of: A) a complete opportunity set. B) the portion of the opportunity set located below the minimum variance portfolio. C) only the minimum variance portfolio. D) the dominant portion of the opportunity set. E) only the maximum return portfolio.

the dominant portion of the opportunity set.

The intercept point of the security market line is the rate of return which corresponds to: A) the risk-free rate of return. B) the market rate of return. C) a value of zero. D) a value of 1.0. E) the beta of the market.
