The risk-free asset has a return of 1.62%. The risky asset has a return of 8.82% and has a variance of 8.82%. Karen has the following utility function: LaTeX: U=a\times\sqrt{r_{c\:}}-b\times\sigma_cU = a × r c − b × σ c, with a=1.3 and b=8.78. LaTeX: r_cr c and LaTeX: \sigma_cσ c denote the return and the risk of the combined portfolio. The optimal amount to be invested in the risky portfolio is 33.85% . (Note: this solution does not necessarily correspond to the ACTUAL optimal solution, but assume it is to answer this question). Compute Karen's utility when she invests optimally

Expert Solution

Compute Karen's utility when she invests optimally

=1.3*(33.85%*8.82%+(1-33.85%)*1.62%)-8.78*(33.85%*sqrt(8.82%))
=-0.8299

Question 4: Suppose a risk-free asset has a 3 percent return and a second risky asset has a 15 percent expected return with a standard deviation of 25 percent. Calculate the expected return and standard deviation of a portfolio consisting of 15 percent of the risk-free asset and 85 percent of the second asset. Provide your final answers up to two decimal points

If the expected return on a risky asset is 13%, standard deviation is 25%, and the risk free asset 5%.

If the expected return on a risky asset is 13%, standard deviation is 25%, and the risk free asset 5%.Calculate the expected return , standard deviation, sharp ratio for the complete portfolio with y= .60

You invest all your money into a risky asset and a risk-free asset. The risky asset has an expected return of 0.065 and a standard deviation of 0.25, the risk-free asset returns 0.025. What is the return on your combined portfolio if you invest 0.4 in the risky asset, and the remainder in the risk-free asset? Round your answer to the fourth decimal point.

Q1) You have a portfolio of one risky asset and one risk-free asset. The risky asset has an expected return of 20% and a variance of 16%. The T-bill rate (that is the risk-free rate) is 6%. Your client Mary is thinking of investing 75% of her portfolio in the risky asset and the remaining in a T-bill. If Mary wants to find a general equation for the expected return and risk of her portfolio what are the equations that...

14. In a universe with just two assets, a risky asset and a risk-free asset, what is the slope of the Capital Allocation Line if the Expected return of the risky asset is 6.22% and the standard deviation of the returns of the risky asset is 23.4%. The return on the risk-free asset is 3.21% Report 2 decimals. 17. An investment opportunity has 4 possible outcomes. The possible returns in each of these outcomes are -7.1%, 0.1%, 4.8% and 14.6%....

Discuss the implications of combining a risk-free asset with a portfolio of risky assets.

The expected return on a risky asset depends only on that asset’s systematic risk.

1. Suppose we have one risky asset Stock I and a risk-free asset. Stock I has an expected return of 25% and a beta of 2. The risk-free asset’s return is 6%. (15 marks total) a. Calculate the expected returns and betas on portfolios with x% invested in Stock I and the rest invested in the risk-free asset, where x% = 0%, 25%, 75%, 100%, 125%, and 150%. b. What reward-to-risk ratio does Stock...
