Exam 25: Calculating Beta Coefficients

Given the following returns on Stock Q and "the market" during the last three years,what is the difference in the calculated beta coefficient of Stock Q when Year 1 and Year 2 data are used as compared to Year 2 and Year 3 data? (Hint: Think rise over run.)

Hanratty Inc.'s stock and the stock market have generated the following returns over the past five years: What is the estimated beta of Hanratty Inc.'s stock?

Stock X and the "market" have had the following rates of returns over the past four years. 60% of your portfolio is invested in Stock X and the remaining 40% is invested in Stock Y.The risk-free rate is 6% and the market risk premium is also 6%.You estimate that 14% is the required rate of return on your portfolio.What is the beta of Stock Y?

Exhibit 8A.1 You have been asked to use a CAPM analysis to choose between Stocks R and S, with your choice being the one whose expected rate of return exceeds its required return by the widest margin. The risk-free rate is 6%, and the required return on an average stock (or the "market") is 10%. Your security analyst tells you that Stock S's expected rate of return is equal to 11%, while Stock R's expected rate of return is equal to 12%. The CAPM is assumed to be a valid method for selecting stocks, but the expected return for any given investor (such as you) can differ from the required rate of return for a given stock. The following past rates of return are to be used to calculate the two stocks' beta coefficients, which are then to be used to determine the stocks' required rates of return: Note: The averages of the historical returns are not needed, and they are generally not equal to the expected future returns. -Refer to Exhibit 8A.1.Set up the SML equation and use it to calculate both stocks' required rates of return,and compare those required returns with the expected returns given above.You should invest in the stock whose expected return exceeds its required return by the widest margin.What is the widest positive margin,or greatest excess return (expected return − required return)?

Which of the following statements is CORRECT?

That is,what is the value of beta_R − beta_S? (Hint: The graphical method of calculating the rise over run,or (Y₂ − Y₁)divided by (X₂ − X₁)may aid you.)

Below are the returns for the past five years for Stock S and for the overall market: What is the estimated beta of Stock S?

Given the following returns on Stock J and the "market" during the last three years,what is the beta coefficient of Stock J? (Hint: Think rise over run.)
