a) What is the portion of the portfolio with 200 shares of stock A with $ 50 per share and 150 shares with share of $ 30?
b) Assume that there is a portfolio of $ 3,500 in stock A and $ 4,500 in stock B. Assuming that the expected returns of these stocks are 11% and 15%, what is the expected return on this portfolio?
c) Invest $ 10,000 in a portfolio of stocks. Stocks that can be selected are stocks with expected return of 11.5% × and stocks with 9.4%. If your goal is to make the expected return on your portfolio 10.85%, how much money should you invest in Stock X? How much money should you invest in Stock Y?
