If you wished to build an efficient position with a return volatility of precisely 36%, explain how you would do so. Give an intepretation of the portfolio weights that you would employ and also compute the expected return on this position. (5 marks) c. Stock Z has an equilibrium expected return of 10% and a return volatility of 45%. What is its beta? Interpret the beta and work out, and then interpret, what it implies for the value of the correlation be- tween the returns on the market and the returns on Z. (5 marks) d. Compute the systematic and idiosyncratic risks for Z and interpret each of them
