Data: So 100; X-120; 1 + r= 1.2. The two possibilities for ST are 130 and 80 a-1. The range of S is 50 while that of C is 10 across the two states. What is the hedge ratio of the call? (Round your answer to2 decimal places.) Hedge ratio a-2. Calculate the value of a call option on the stock with an exercise price of 120. (Do not use continuous compounding to calculate the present value of X in this example because we are using a two-state model here with discrete periods, not a continuous-time Black-Scholes model.) (Do not round intermediate calculations. Round your answer to 2 decimal places.) Call value
