Suppose that you have $5,000 to invest in stocks 1, 2, and 3 with current prices [S(to) S2(to) [Ss(to)] [$10.20 $53.75 $30.45 covariance matrix, 0.03 -0.04 0.02 -0.04 0.08 -0.04 0.02 -0.04 0.04 and expected return vector [0.010] 0.15 [0.075] For example, stock 3 has a volatility of o3 = 20% and expected return rate of 3 = 7.5%. The values in V and u are pure numbers (not percentages). Answer the following questions. a. Determine the weights needed to create the global minimum-variance portfolio of these three stocks. b. Create an efficient portfolio with an expected return rate of 18%. Explicitly state the number of shares one must hold for each stock and how you fund each position. State the port folio risk and compare it with maximum risk among the stocks.
