- Based on current dividend yields and expected capital gains, the expected rates or return on portfolios A and B are 12% and 18%, respectively. The beta of A is 0.7 while that of B is 1.6. The T-bill rate is currently 4% while the expected rate of return of the S&P500 Index is 13%. The standard deviation of portfolio A is 14% annually, while that of B is 26%, and that of the index is 15%. If instead you could invest only in bills and one of these porfolios, which would you choose? Use the sharpe ratio to make your desicion.arrow_forwardBased on current dividend yields and expected capital gains, the expected rates of return on portfolios A and B are 11 % and 14 %, respectively. The beta of A is 0.8 % while that of B is 1.5. The T-bill is currently 6 %, while the expected rate of return of the S&P 500 index is 12 %. The standard deviation of portfolio A is 10 % annually, while that of B is 31 % , and that of the index is 20 %: If you currently hold a market index portfolio, would you choose to add either of these portfolios to your holdings? Explain. If instead you could invest only in bills and one of these portfolios, which would you choose, and why? Investor Y, who put K1 in large stocks (the S & P 500 portfolio) on December 31, 1925, and re-invested all dividends in that portfolio, would have ended on December 31, 2003, with K1992.80.arrow_forwardBased on current dividend yields and expected capital gains, the expected rates of return on portfolios A and B are 13% and 15% respectively. The beta of A is 0.8 while that of B is 1.3. The T-bill rate is currently 7% while the expected rate of return of the S&P500 index is at 14%. The standard deviation of portfolio A and B are 20% and 41%, and that of the index is 30%. Compare the performance of the two portfolios relative to the market using the four performance measures: Sharpe ratio, Treynor ratio, Jensen's Alpha and M?. Comment on the calculated results. а. b. Would you choose to add A or B to your holdings if you currently hold a market-index portfolio? Justify your decision. Which portfolio would you choose if instead you could invest only in Treasury bills and one of these portfolios? Explain your answer. с. Could a portfolio show a higher Sharpe ratio but a lower M² measure at the same time? Explain your answer. с.arrow_forward
- Consider two types of assets: market portfolio (M) and stock A. The expected return is 8% and standard deviation of the market portfolio is 15%. The risk-free rate is 2%. The standard deviation of market portfolio returns is 15%. The standard deviation of stock A is 30%, and the beta coefficient is 1. Draw the capital market line and show the position of stock A.arrow_forwardConsider historical data showing that the average annual rate of return on the S&P 500 portfolio over the past 85 years has averaged roughly 8% more than the Treasury bill return and that the S&P 500 standard deviation has been about 21% per year.
