Question

Suppose that S1 and S2 are correlated, non-dividend-paying assets that follow geometric Brownian motion. Specifically, let S1(0) = S2(0) = \$100, r = 0.06, σ1 = 0.35, σ2 = 0.25, ρ = 0.40 and T = 1. Verify that the following two procedures for valuing an outperformance option give a price of approximately \$13.464.
a. Use Monte Carlo simulation to simulate both S1(T ) and S2(T ) to value the payoff max(0, S1(T)− S2(T ))
b. Use Monte Carlo simulation to simulate only S1(T )/S2(T ), and value the payoff S2(0) max(0, S1(T )/S2(T ) − 1)
