Binomial Trees Consider a stock which currently sells for 40. Assume that during each two-month period for the next four months this share price is expected to increase by 2% or decrease by 2% and the risk-free interest rate is 2.5% per annum (cont. comp.). Consider an exotic derivative that has a payoff given by the formula (max[(42.50-ST),0])2 where ST is the stock price in four months. a. Draw a two-step binomial tree and populate the individual nodes with the share price values at each node. b. If this derivative is of European-style, value the derivative using no-arbitrage arguments. c. If this derivative is of European-style, value the derivative using risk-neutral valuation. d. Verify whether both approaches lead to the same result. e. If the derivative is of American style, should it be exercised early if the payoff at time t is given by the formula (max[(42.50 - St),0])2? Note: When you use no-arbitrage arguments, you need to show in detail how to set up the riskless portfolios at the individual nodes of the binomial tree.
