6. Write in the appropriate box Returns for Patel's Returns for Padice's Stock Stock Aggressive stock Higher firm specific risk Higher total risk In figure I below, Li represents the regression equation for Defensive stock Less systematic risk The market returns explain a greater fraction of return variability Higher alpha Figure 1 Security Return (R) Market Return (R.) Suppose that you were to construct a portfolio with proportions as follow: Paltel Stock 30%, Padico Stock 50%, and T-bill 20% 7. Compute the beta of the portfolio? (1 mark) (1 mark) 8. Compute the non-systematic risk of the portfolio (1 mark) 9. Compute the standard deviation of the portfolio 10. Roa argues that the covariance between the returns on Paltel and Padico's stocks is the same under both the single index model and Markowitz model. Do you agree with this argument? Discuss and support your views numerically with formulas. (2 marks) 6.
