- 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_forwardWhich 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_forwardAttached imagearrow_forward
- Concepts of Risk. In broad terms, why is some risk diversifiable? Why are some risks non-diversifiable? Does it follow that an investor can control the level of unsystematic risk in a portfolio, but not the level of systematic risk?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_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_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
- Which one of the following expressions about risk and returns is wrong? A. In general, one reason why a stock is riskier than a bond is that because cash flows from a bond are known and promised, whereas cash flows from a stock are neither known nor promised. B. According to CAPM model, a well-diversified portfolio will have a beta which equals to 0. C. Risk premium is the extra return provided on risky assets to compensate for risk. The difference between risky return and the risk-free return. D. Unexpected return happened because new information came to light which caused our expectations about prices and returns to change.arrow_forwardWhich of the following arguments has been put forward as a criticism of using the PEG ratio as the basis of an investment strategy? Select one: a. The PEG ratio buys growth stocks without any consideration of their price. b. Stocks with a low PEG ratio are all large cap stocks. c. Stocks with a low PEG ratio have been shown to generate lower stock returns. d. Stocks with a low PEG ratio also have a positively skewed distribution of returns. e. Stocks with a low PEG ratio are shown to be riskier.arrow_forwardExercises: a. The standard deviation of returns is 0.30 for Stock A and 0.20 for Stock B. The covariance between the returns of A and B is 0.006. The correlation of returns between A and B is: b. Explain the differences between systemic risk and unsystematic risk, give additional examples c. Compare and contrast the Capital Market Line and Security Market Line d. The covariance of the market's returns with the stock's returns is 0.008. The standard deviation of the market's returns is 0.08, and the standard deviation of the stock's returns is 0. 11. What is the correlation coefficient of the returns of the stock and the returns of the market? e. According to the CAPM, what is the required rate of return for a stock with a beta of 0.7, when the risk-free rate is 7% and the expected market rate of return is 14%arrow_forward
