3. A market consists of two risky assets and no risk-free asset. Let R₁ and R2 denote the return on each of the risky assets. Using market data the following have been estimated: E[R₁] = 0.10, E[R₂] = 0.15, o2 = Var (R₁)=0.1², o2 = Var(R₂) = 0.2² and p1,2 = -1/ where p1,2 denotes the correlation coefficient for R₁ and R₂. (i) Given that an investor is targeting a total expected return of u = 0.125 on a portfolio, what is the minimum variance that can be achieved? (ii) Determine the global minimum variance portfolio and the expected return and variance of return on this portfolio. (iii) Using your answers to parts (i) and (ii) make a rough sketch of the minimum- variance set in μ-2 space. You should indicate the efficient frontier and the global minimum variance portfolio. (iv) Without further calculation, explain how you would expect the variance of return calculated in (ii) to change if the two risky assets were independent.
