[6 marks] b. State the assumptions and implications of the two-fund separation theorem C. [5 marks] Consider two stocks A and B. Both have an expected return of 10%, their standard deviations are 18% and 16% respectively, and their correlation is 0.35. Finally, the risk-free rate of return is 3%. Assuming all the assumptions of the one-fund theorem hold true, Required: . Identify the composition of the minimum variance portfolio, and calculate its expected return and standard deviation. ii. iii.
