Vlad has estimated the average continuously-compounded, annualised monthly returns on 3 different stocks, A, B, and C. They are shown in the table below. Stock average returns A 5% B 8% 3% Vlad has also gathered evidence supporting the view that: the monthly returns on the three stocks are uncorrelated; the standard deviations of the simple monthly returns on the three stocks are equal; and the monthly returns on the three stocks are independently and identically distributed over time. [4 points] A) Compute the average annualised simple monthly returns on each of the assets and on an equally weighted portfolio of the three stocks. [2 points] B) Would Vlad be better off with unequal portfolio weights? Explain your reasoning without attempting to compute specific optimal weights. [4 points] C) If the standard deviations of the annualised simple monthly returns are all equal to 10% and the simple monthly risk-free rate of return is 1%, what is the Sharpe ratio for an equally weighted portfolio
