1. Suppose that The Warehouse currently trades at $2.04. The interest rate is l% (with contintious coinpounding), and The Warehouse shares have a volatility of 18%. Set up a two step binomial tree for the stock, with each step representing three months. (a) What is the value of a European call option with strike price $2.15, maturing in six months (b) What is the value of a European put option with strike price $2.15 maturing in six months (c) Verify that the put-call parity relationship holds. time? time! 2. A stock price is currently $25. The interest rate is 6% (with continuous compounding). Volati- ity is 12% per annum. In 12 months time, an exotic derivative pays off ., where Si is the stock price after 12 months. What is the value of this derivative? Use a two step binomial tree to value it
