Data: Se 100; X=110; 1+r=1.1. The two possibilities for ST are 130 and 30. Required: a-1. The range of S is 100 while that of C is 20 across the two states. What is the hedge ratio of the call? Note: Round your answer to 2 decimal places. a-2. Calculate the value of a call option on the stock with an exercise price of 110. (Do not use continuous compounding to calculate the present value of X in this example because we are using a two-state model here; the assumed 10% interest rate is an effective rate per period.) Note: Do not round intermediate calculations. Round your answer to 2 decimal places.
