Compute the expected return and standard deviation of a portfolio composed of 25% ABC and XYZ. 2 3 4 5 ABC xyz Covariance(ABC,XYZ) Correlation ABC,XYZ Expected return 15% 25% 0.0865 0.5698 Standard deviation of return 33% Compute the returns of all portfolios that are combinations of ABC and XYZ with the propor- tion of ABC being O, 10, , 90, 100%. Graph these returns. Compute the minimum variance portfolio. II. Melissa Jones wants to invest in a portfolio composed of stocks ABC and XYX (from Question 10), that will yield a return of 19%. What is the weight of each stock in such a portfolio, and what is the portfolio's standard deviation? Answer the question both using Excel's Goal Seek or Solver and using the mathematical formulas in the chapter (page 322).
