The situation where more reduction of risk could be achieved by spreading the investment across two stocks is-
There is no correlation.
There is perfect negative correlation
There is modest negative correlation
The two stocks are perfectly correlated
Which of the following statements is false?
A.
The lower the correlation coefficient, the greater the potential benefits from diversification.
B.
To make the covariance of two random variables easier to interpret, it may be divided by the product of the random variables’ standard deviation. The resulting value is called the correlation coefficient, or simply, correlation.
C.
The risk that remains cannot be diversified away and is called the systematic risk.
D.
In the event of bankruptcy, preferred stock ranks below common stock but above debt.
When seeking to diversify and eliminate unsystematic risk in your portfolio, do you want stocks whose movements have high correlation (i.e. move together) or low correlation (i.e. don't move togeter).
a) High correlation
b) Low correlation

- Calculate the correlation coefficient between Blandy and the market. Use this and the previously calculated (or given) standard deviations of Blandy and the market to estimate Blandy’s beta. Does Blandy contribute more or less risk to a well-diversified portfolio than does the average stock? Use the SML to estimate Blandy’s required return.arrow_forwardAccording to modern portfolio theory, the idea that investors with different indifference curves will hold the same portfolio of risky securities is a result of O a. the separation theorem O b. covariance O c. the normal distribution assumption O d. diminishing marginal utility of incomearrow_forwardDiversification refers to the _________.a. reduction of the stand-alone risk of an individual investment, measured by its beta coefficient, by combining it with other investments in a portfolio b. reduction of the stand-alone risk of an individual investment, measured by the standard deviation of its returns, by combining it with other investments in a portfolio c. reduction of systematic risk of an individual, measured by its beta coefficient, by combining it with other investments in a portfolio d. reduction of systematic risk of an individual, measured by the standard deviation of its returns, by combining it with other investments in a portfolio e. reduction of the unsystematic risk of an individual, measured by its coefficient of variation, by combining it with other investments in a portfolioarrow_forward
- Which of the following is true? a. Beta of a stock cannot be negative b. SML is an acronym for Stock Market Line c. Holding multiple stocks from the same industry is meaningful diversification d. Undiversifiable risk is known as the systematic riskarrow_forwardWhat does beta represent? Multiple Choice Beta is a measure of covariance standardized by the variance of the market. This adjusts the risk of the firm to be relative to the risk of the market. Beta is the extra income earned on an investment that cannot be explained by systematic risk or unsystematic risk. Beta is related to the return on risk-free assets. Beta is always positive or O, it cannot be negative because stock prices cannot be negative.arrow_forwardDiversification occurs when stocks with low correlations of returns are placed together in a portfolio. Identify at least one type of firm that might exhibit low correlations of returns with the overall stock market? Explain why the correlations of these firms are expected to be low.arrow_forward
- Which of the following statements regarding beta is false: a. Beta is a measure of systematic risk. b. The beta of a share is calculated as the covariance between the share and the market divided by the variance of the market. c. If the returns of two firms are negatively correlated, then one of them must have a negative beta. d. A share with a beta equal to -1 has zero systematic risk. e. A share’s beta is more relevant as a measure of risk to an investor with a well-diversified portfolio than to an investor who holds only one share.arrow_forward1. The diversifiable risk of a portfolio: a. Is correlated with systematic risk. b. Can be made sufficiently small. c. Is zero in the real world. d. Is the risk that investors lose because of transaction costs. Which one of the following conditions determines the investor’s overall optimal portfolio? a. The marginal ratio of substitution of the investor’s utility function must be equal to the Sharpe ratio of the optimal risky portfolio. b. The standard-deviation of the overall portfolio in minimised. c. The expected return of the overall portfolio is maximised. d. The slope of the Sharpe-ratio is equal to zero. 4. Markets can never be strong-form efficient because: a. There are too many traders in them. b. Investors are rational. c. Information is costly to acquire. d. All information is public. 5. Which one of the following is not a property of a pure arbitrage portfolio? a. Zero investment. b. Zero systematic risk. c. Positive net return. d. All of the above.arrow_forwardSelect all that are takeaways with respect to risk and return in financial markets that we gleaned from historical data. Group of answer choices In a competitive market, one should expect higher returns for taking on more risk In a competitive market, one will earn a higher return if they take on more risk Individual stocks and portfolios (of those individual stocks), by definition, exhibit the same risk-return trade offs We use historical data to quantify the risk-return relation because we know this same relation will hold in the futurearrow_forward
- Which of the following statements about 'beta' is correct? Is a measure of stand-alone risk. A low beta means that a stock is more volatile than the market Is a measure of a stock's volatility relative to the market. OA high beta means that a stock is less volatile than the marketarrow_forwardBased on the CAPM model, a stock with a negative beta has which of the following characteristics? A. An expected return less than zero. B. An expected return equal to the risk-free rate. C. Since these are so rare, the CAPM model does not account for negative beta stocks. D. An expected return less than the risk-free rate.arrow_forwardDiversification works because: Select one: a. Portfolios have higher returns than individual assets. O b. Firm-specific risk can be never be reduced. O c. Stocks earn higher returns than bonds. O d. Unsystematic risk exists. O e. Forming stocks into portfolios reduces the standard deviation of returns for each stock.arrow_forward
