Consider a portfolio that offers an expected rate of return of 13% and a standard deviation of 20%. T-bills offer a risk-free 4% rate of return. What is the maximum level of risk aversion for which the risky portfolio is still preferred to T-bills? (Do not round intermediate calculations. Round your answer to 2 decimal places.) Maximum level of risk aversion must be
Asset A has a standard deviation of 0.17, and asset B has a standard deviation of 0.52. Assets A and B have a correlation coefficient of 0.44. What is the standard deviation of a portfolio consisting with a weight of 0.40 in asset A, a weight of 0.24 in asset B, and the remainder invested in a risk-free asset? Give your answer to four decimal places.
The beta on risky asset A is 1.8 and the beta on risky asset B is 1.1. The expected return on the market portfolio is 10% and the risk free rate of return is 4%. Consider a portfolio comprising the two risky assets and the risk-free asset where you invest 50% in risky asset A and 30% in risky asset B. What is (i) the beta of a portfolio and (ii) the expected return of the portfolio? a None of the above b (i) 0.97 and (ii) 9.82% c (i) 1.23 and (ii) 9.82% d (i) 1.23 and (ii) 11.38% e (i) 0.97 and (ii) 11.38%
Suppose the risk free rate is 5% and the market portfolio has an expected return of 10%. Portfolio Z has a correlation coefficient with the market of 0.1 and a variance of 0.16. The market portfolio has a variance of 0.09. According to the CAPM, what is the beta of portfolio Z?
You are constructing a portfolio of two assets, Asset A and Asset B. The expected returns of the assets are 12 percent and 16 percent. respectively. The standard deviations of the assets are 29 percent and 37 percent, respectively. The correlation between the two assets is 41 and the risk-free rate is 3.4 percent. What is the optimal Sharpe ratio in a portfolio of the two assets? What is the smallest expected loss for this portfolio over the coming year with a probability of 2.5 percent? (A negative value should be indicated by a minus sign. Do not round intermediate calculations. Round your Sharpe ratio answer to 4 decimal places and the z-score value to 3 decimal places when calculating your answer. Enter your smallest expected loss as a percent rounded to 2 decimal places.) Sharpe ratio Smallest expected loss %
Suppose an investor uses two stocks A and B to build a risky portfolio. The following information is given: E(r_A)=10%,E(r_B)=12%,0_A=15%,o_B=20%, p_AB=0.4,r_f=2%. Denote the optimal risky portfolio investor can achieve with the highest Sharpe ratio by portfolio O. Calculate the weights of A and B (w_A and w_B) in the optimal risky portfolio O. Calculate the expected return and standard deviation of return for portfolio O. Calculate the Sharpe ratio of portfolio O.
You own a portfolio equally invested in a risk-free asset and two stocks. If one of the stocks has a beta of 1.25 and an expected return of 15%. The other stock has an expected return of 21%. The total portfolio is equally as risky as the market (i.e.Bp=1). What is the beta for the other stock in your portfolio? What is the expected return of the risk-free asset? What is the expected return of the market? What is the expected return of your portfolio?
Consider the single factor APT. Portfolio A has a beta of 1.5 and an expected return of 20 %. Portfolio B has a beta of 0.7 and an expected return of 16%. The risk - free rate of return is 8%. If you wanted to take advantage of an arbitrage opportunity, you should take a short position in portfolio and a long position in portfolio
An investor can design a risky portfolio based on two stocks, A and B. Stock A has an expected return of 15% and a standard deviation of return of 16.0%. Stock B has an expected return of 11% and a standard deviation of return of 4%. The correlation coefficient between the returns of A and B is 0.50. The risk-free rate of return is 7%. The proportion of the optimal risky portfolio that should be invested in stock A is __________.
An investor can design a risky portfolio based on two stocks, A and B. The standard deviation of return on stock A is 25% while the standard deviation on stock B is 15%. The correlation coefficient between the return on A and B is 0.40. What is the standard deviation of return on the minimum variance portfolio? Do not enter % in the answer box. For example, if your answer is 0.12345 or 12.345% then enter as 12.35 in the answer box.
jordan's portfolio is comprised of the risk-free asset and the market index. what is the standard deviation of Jordan's portfolio that has a beta of 1.7 if the risk-free rate is 0.3%, the return on the market index is 7.2% and the standard deviation on the market index is 21%
Consider two portfolios, Portfolio A and Portfolio B, with the following performance metrics: - Portfolio A has a Sharpe Ratio of 0.8, a Treynor Ratio of 1.2, and a Jensen's Alpha of 0.5. - Portfolio B has a Sharpe Ratio of 1.2, a Treynor Ratio of 0.9, and a Jensen's Alpha of -0.2. Which of the following statements is correct regarding the performance of these portfolios? Portfolio A has a higher risk-adjusted return when the risk is measured by the beta. Portfolio B outperforms the risk-adjusted return suggested by CAPM. Portfolio A and B have similar risk-adjusted returns, but Portfolio B exhibits negative abnormal returns. Portfolio B has a higher risk-adjusted return when the risk is measured by the standard deviation. Portfolio A outperforms Portfolio B in terms of both risk-adjusted return and abnormal returns suggested by CAPM.
