Consider the binomial model for an American call and put on a stock that pays no dividends. The current stock price is $120, and the exercise price for both the put and the call is $110. The standard deviation of the stock returns is 0.4, and the risk-free rate is 10 percent. The options expire in 120 days. Find the price of these options using a four-period tree. Draw the stock tree and the corresponding trees for the call and the put. Explain when, if ever, each option should be exercised. What is the value of a European call in this situation? Can you find the value of the European call without making a separate computation? Explain.
