INV 1 4a
You have invested in a portfolio of 60% in risky assets (Portfolio R) and 40% in T-bills. The risky portfolio is described below:
E(rR)=12%
σR =15%
- If the T-bill rate is 3%, what is the expected return on your overall portfolio, including both portfolio R and the T-bills?

What is the expected return of the following portfolios: one that invests 0% in A, one that invests 10% in A, 20% in A and so on until 100%?

The T-bill rate (risk-free rate) is 7%. Your client chooses to invest 70% in the risky portfolio in your fund and 30% in a T-bill money market fund. We assume that investors use mean-variance utility: U = E(r) – 0.5 x Aa?, where E(r) is the expected return, A is the risk aversion coefficient and o? is the variance of returns. a) What is the expected value and standard deviation of the rate of return on your client's portfolio? b) What is the reward-to-volatility ratio (Sharpe ratio) of your risky portfolio? What is the reward-to-volatility ratio (Sharpe ratio) of your client's risky portfolio? Comment on the relationship between these two Sharpe ratio calculated and explain the intuition behind. c) Draw the Capital Allocation Line (CAL) of your portfolio on an expected return- standard deviation diagram.
