3. Consider Table 5. Each part of question 3 carry equal marks. Systematic Unsystematic Risk Risk Table 5 Security Variance Correlation Average Alpha Market i of i and Returns Beta Market 1 0.80 2% 2 14% 0.60 1% 3 16% 0.20 1% Market 18% 1.00 9% 1.00 12% (a) Consider Table 5. Calculate the market beta for securities 1, 2, and 3. Detail all calculations that you use. (b) Consider Table 5. Using the single model, calculate systematic and unsystematic risk for securities 1, 2, and 3. Detail all calculations that you use. (c) Consider Table 5. Using the single index model, calculate the expected returns for securities 1, 2, and 3. Also, using the single index model, calculate the covariance between the returns of security 1 and security 2, and security 1 and security 3, respectively. Detail all calculations that you use. (d) Consider Table 5. Form a portfolio of securities 1 and 2. Invest 75% in security 1 and 25% in security 2. What is the expected return and standard deviation risk of this portfolio? Sketch the minimum variance frontier comprised of security 1 and security 2. Detail all calculations that you use
