Proportion of risky assets= (Expected return - Risk free return)/ (A * SD^2)
1.25 = (0.09 - 0.03) / (A * 0.15^2)
1.25 = (0.06 / (A * 0.0225)
A * 0.0225 = 0.06 / 1.25
A * 0.0225 = 0.048
A = 0.048 / 0.0225
A = 2.13
Investor's risk aversion coefficient (A) = 2.13

Question 19 5 pts A risky fund has an expected return of 10% and standard deviation of 18%. The risk-free rate is 6%. Arisk-averse investor having a risk aversion coefficient (A) equal to 3.5. is considering investing a portion of her retirement money in the risky fund with the remainder in cash. The Sharpe ratio of her optimal complete portfolio is: O 0.22 045 0.35 Can't tell from information provided. Need the return and risk of the optimal complete portfolio....
You manage a risky portfolio that has an expected return of 9% and a standard deviation of returns of 12.5%. The T-bill rate is 3%. Your client wants to allocate her investment portfolio between your fund and T-bills to achieve an expected rate of return of 7%. What proportion of her portfolio should she allocate to the risky portfolio? What proportion to T-bills? What is the standard deviation of her portfolio? Another client wants to allocate his investment portfolio between...
Consider a portfolio that offers an expected rate of return of 10% and a standard deviation of 24%. T-bills offer a risk-free 6% rate of return. What is the maximum level of risk aversion for which the risky portfolio is still preferred to T-bills?
Consider a portfolio that offers an expected rate of return of 12% and a standard deviation of 22%. T-bills offer a risk-free 5% 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.)
3. You have a risky portfolio that yields an expected rate of return of 15% with a standard deviation of 25%. Draw the CAL for an expected return/standard deviation diagram if the risk free rate is 5%. a. What is the slope of the CAL? b. If your coefficient of risk aversion is 5, how much should you invest in the risky portfolio? 4. A pension fund manager is considering three mutual funds. The first is a stock fund, the...
An investor has a risk aversion coefficient of 5. The expected return and standard deviation of the optimal risky portfolio are 15% and 25%, respectively. If the Sharpe ratio of the optimal capital allocation line is 0.48, what is the proportion of the investor’s combined portfolio that should be invested in the risky portfolio that would maximise their utility?
Consider a portfolio that offers an expected rate of return of 12% and a standard deviation of 25%. T-bills offer a risk free return rate of What is the maximum level of risk aversion for which the risky portfolio is still preferred to Tbilis? (Do not round Intermediate calculations.
