We will derive a two-state call option value in this problem. Data: S0 = $190; X = $200; 1 + r = 1.10. The two possibilities for ST are $220 and $120. The portfolio consists of 1 share of stock and 5 calls short. Required: a. The range of S is $100 while that of C is $20 across the two states. What is the hedge ratio of the call? (Round your answer to 2 decimal places.) b. Calculate the value of a call option on the stock wit
We will derive a two-state call option value in this problem. Data: S0 = $190; X = $200; 1 + r = 1.10. The two possibilities for ST are $220 and $120. The portfolio consists of 1 share of stock and 5 calls short.
Required:
a. The range of S is $100 while that of C is $20 across the two states. What is the hedge ratio of the call? (Round your answer to 2 decimal places.)
b. Calculate the value of a call option on the stock with an exercise price of $200. (Do not use continuous compounding to calculate the present value of X in 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.)
