Problem 2: Binomial Trees

A stock price is currently $40. Over each of the next two three-month periods it is expected to go up by 10% or down by 10%. The risk-free interest rate is 7% per annum with continuous compounding.

  1. Use a two-step binomial tree to calculate the value of a six-month European put option with a strike price of $42.
  2. Use a two-step binomial tree to calculate the value of a six-month American put option with a strike price of $42.
  3. Use a two-step binomial tree to calculate the value of a six-month European call option with a strike price of $42.
  4. Show whether the put-call-parity holds for the European put and the European call. Also calculate the deltas of the European put and the European call at the different nodes of the binomial tree.Hint: You need to calculate three deltas for the call and three deltas for the put.
