Suppose that the risk free rate is 5% per year. We wish to value a 2-year American call option with a strike price of $110. The current stock price is $100. Each year, the stock price either increases 10%, or decreases by 5% Here are the steps for you to solve the problem a) Construct a two-period binomial tree for the value of the stock. (5 points) b) Calculate the value of the American call option. (10 points) c) Write down the put-call parity relationship for this option. (2 points) d) What will be the value of the European put option with an exercise price of 110? (3 points) Suppose that the risk free rate is 5% per year.
