In lecture, I claimed that one could synthesize contingent claims when there were fewer securities than states, by dynamic trading. Let's work out an example. There are two dates. There are two securities: 1) A stock has price 1 and either rises or declines in each state. 2) A one-period risk-free rate with 0% return, i.e. payoff and price 1.
(This is a "nonrecombining binomial tree.")
Find the dynamic trading strategy that creates a contingent claim to the first of the final states, that is, if the "up" move occurs twice in a row. This means, find the investment in stock and bond at the first node, and the investment in each of the two nodes at time 1 that produces the final payoff . Find also the time-0 price of this contingent claim,
