Binomial lattice model for stock prices
... Now consider a European call option for one share of the stock, with strike price K, and expiration date t = 1. The payoff to the holder of this option at time t = 1 is a random variable given by C1 = (S1 − K)+ ; the buyer of such an option is thus betting that the stock price will be above K at the ...
