What does beta represent?Multiple ChoiceBeta 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 themarket.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.

Beta of a stock measures the volatility with relation to the overall market. Market has a beta of 1,…

What is a characteristic line? How is this line used to estimate a stocks beta coefficient? Write out and explain the formula that relates total risk, market risk, and diversifiable risk.
You have been hired at the investment firm of Bowers & Noon. One of its clients doesn’t understand the value of diversification or why stocks with the biggest standard deviations don’t always have the highest expected returns. Your assignment is to address the client’s concerns by showing the client how to answer the following questions: What is the Capital Asset Pricing Model (CAPM)? What are the assumptions that underlie the model? What is the Security Market Line (SML)?
You have been hired at the investment firm of Bowers & Noon. One of its clients doesn’t understand the value of diversification or why stocks with the biggest standard deviations don’t always have the highest expected returns. Your assignment is to address the client’s concerns by showing the client how to answer the following questions: Suppose a risk-free asset has an expected return of 5%. By definition, its standard deviation is zero, and its correlation with any other asset is also zero. Using only Asset A and the risk-free asset, plot the attainable portfolios.
You have been hired at the investment firm of Bowers Noon. One of its clients doesnt understand the value of diversification or why stocks with the biggest standard deviations dont always have the highest expected returns. Your assignment is to address the clients concerns by showing the client how to answer the following questions: d. Construct a plausible graph that shows risk (as measured by portfolio standard deviation) on the x-axis and expected rate of return on the y-axis. Now add an illustrative feasible (or attainable) set of portfolios and show what portion of the feasible set is efficient. What makes a particular portfolio efficient? Dont worry about specific values when constructing the graphmerely illustrate how things look with reasonable data.
Which of the following statements is CORRECT? a. The SML shows the relationship between companies' required returns and their diversifiable risks. The slope and intercept of this line cannot be influenced by a firm's managers, but the position of the company on the line can be influenced by its managers. b. Suppose you plotted the returns of a given stock against those of the market, and you found that the slope of the regression line was negative. The CAPM would indicate that the required rate of return on the stock should be less than the risk-free rate for a well-diversified investor, assuming investors expect the observed relationship to continue on into the future. c. If investors become less risk averse, the slope of the Security Market Line will increase. d. If a company increases its use of debt, this is likely to cause the slope of its SML to increase, indicating a higher required return on the stock. e. The slope of the SML is determined by the value of beta.
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.
Which of the following is NOT a potential problem when estimating and using betas, i.e., which statement is FALSE? a. Sometimes, during a period when the company is undergoing a change such as toward more leverage or riskier assets, the calculated beta will be drastically different from the "true" or "expected future" beta. b. The beta of an "average stock," or "the market," can change over time, sometimes drastically. c. Sometimes the past data used to calculate beta do not reflect the likely risk of the firm for the future because conditions have changed. d. All of the statements above are true. e. The fact that a security or project may not have a past history that can be used as the basis for calculating beta.
Which of the following statements is INCORRECT? A stock's beta is calculated as the covariance between the stock's price and the market portfolio return, divided by the variance of the market portfolio return. If we assume that the market portfolio (or the S&P 500) is efficient, then changes in the value of the market portfolio represent systematic shocks to the economy. The risk premium investors can earn by holding the market portfolio is the difference between the market portfolio's expected return and the risk-free interest rate. A stock’s standard deviation is a measure of the total risk.
You observe the following information regarding Company ABC and Company XYZ:· Company ABC has a higher expected mean return than Company XYZ.· Company ABC has a lower standard deviation than Company XYZ.· Company ABC has a higher beta than Company XYZ.Given this information, which of the following statements is most correct? Company ABC has more company-specific risk than Company XYZ. Company ABC has a lower coefficient of variation than Company XYZ. Company ABC is a better stock to buy than Company XYZ. Both companies has equal risk
Which of the following is NOT true with respect to standard deviation as a measure of risk? Group of answer choices Standard deviation of return measures the sum of diversifiable and undiversifiable risk for a share. 2. Standard deviation contains more information about distribution of returns by comparison with the more crude approach of measuring the range of possible extreme values for return. 3. Standard deviation is measured in standard units, unlike variance which is measured in squared units, 4. Unlike Beta, standard deviation of return measures undiversifiable risk.
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.
Why will the standard deviation not be a good measure of risk when returns are negatively skewed? What are the risk implications for an investor for a returns series that exhibits fat tails? A price weighted index places more weight on stocks with a higher price, whilst a value weighted index places more weight on stocks with a higher market capitalization. Discuss.
