We will derive a two-state call option value in this problem. Data: 5o = $230; X = $240; 1 + r= 1.10. The two possibilities for St are $260 and $180. The portfolio consists of 1 share of stock and 4 calls short. Required: a. The range of Sis $80 while that of Cis $20 across the two states. What is the hedge ratio of the call? (Round your answer to 2 decimal places.) Hedge ratio b. Calculate the value of a call option on the stock with an exercise price of $240. (Do not use continuous compounding to calculate the present value of Xin this example, because the interest rate is quoted as an effective per-period rate.) (Do not round intermediate calculations. Round your answer to 2 decimal places.) Call value
