Use the information below to answer the following three questions You have identified two portfolios of interest; a stock portfolio which has an expected return of 8.5% p.a., and a bond portfolio that has an expected return of 6.2% p.a. The standard deviation of these portfolios is 42% and 14%, respectively. The risk-free rate of return is 3% p.a. and the covariance between the stock and bond portfolios is 264.6. Your initial thought is that you would like to invest 48% of your wealth into the stock portfolio, and the remainder into the bond portfolio. The expected return of this portfolio is: Select one: a. 7.35% b. 7.75% c. 7.30% d. 7.40% e. 8.86% What is the standard deviation of the portfolio, consisting of 48% invested in the stock component, and 52% in the bonds? Select one: a. 24.32% b. 25.58% c. 28.00% d. 27.44% e. 16.35% You decide that the risk of your portfolio in the previous question is too high. Instead, you would like your portfolio to have a standard deviation of no more than 16%. Assuming that the composition of your risky portfolio remains fixed, the weighting of stock in your complete portfolio is: Select one: a. 0.342 b. 0.658 c. 0.300 d. 0.274 e. 0.316
