Consider a market model with two securities S1 and S2 and three scenarios, 61, 62 and 63 such that P(01) = P(@3) = P(@2)/2 = 0.25 Si(0) = 8, S2(0) = 10 Si(1) = 6 5 12 for 01 for 02, for 03 S2(1) = { 11 11 9 for 01 for 02 for 03 1. Calculate the quantities o?, oz and P12. 2. Compute the weights in the portfolio with minimum risk for the data above. Does this portfolio involve short selling?
