Compute the current value of a European call option.
II. A look back option is a call option that allows the holder to buy the stock at the minimum stock price that occurred over the period to expiration. Suppose, S0 = $129, U = 1.5, D = 0.5, and R = 1.1, use a 3-period binomial model and find the price of such a contract?
III. You are provided with the following information:
S0 = $129, X = $80, U = 1.5, D = 0.5, and R = 1.1
1. Compute the value of a call option using the two-period binomial model.
2. What are the hedge portfolios at t = 1 that help price the call option at that time?
3. Suppose the model price were correct, and the call option were priced in the market at $55. Show how one can make arbitrage profits.
IV. Price a call option using the one-period binomial model assuming the following data:
S0 = 129, K=80, U=1.5, D=0.5 and R=1.1. What does the replicating portfolio consist of?
V. Use the data from problem 5, compute the put price and validate the put-call parity.
