Suppose we obtain the following data in dollar terms: Stock Market United States United Kingdom Return (Mean) 1.20% per month 1.23% per month Risk (SD) 4.43% 5.53% The correlation coefficient between the two markets is 0.28. Suppose that you are forming a portfolio investing in the two market (11 points) (a) Graphically illustrate various combinations of portfolio risk and return that can be generated by investing in the U.S. and U.K. stock markets with different proportions. Two exterem proportions are (a) investing 100 percent in the United States with no position in the U.K. market, and (b) investing 100 percent in the U.K. market with no position in the U.S. market. [Note: Plot the portfolio risk on x axix and portfolio return on y axix. Adjust proportions by 0.1% from 0% to 100%.] (b)How do we form a portfolio that minimizes the portfolio risk? Base your answer on the risk-return combinations generated above by adjusting the proportions by 0.1%. (c) What is the extra return that U.S. investors can expect to capture at the U.S.-equivalent risk level? Base your answer on the risk-return combinations generated above by adjusting the proportions by 0.1%
