Applying binomial trees is a useful and very popular technique for pricing an op-tion, since it is easy to implement. binomial risk neutral option pricing model. . Backward induction: Starting at expiry, we know the payﬀ of the call: 3.2 at (A), 0 at (B), 0 at (C). This essentially means that any stock option potentially qualifies as a binomial model stock option. Now value option as expected discounted value of its cash flows: e-.25(.12)(.65($1) + .35($0)) = $0.63. tisches Modell für die Preisgestaltung von Optionen des europäischen Stils besprochen wird.

Subsequently, the binomial approach to op-tion pricing theory was presented in Sharpe’s textbook ”Investments” [Sha79] and the model was explained in detail in ”Option pricing: a simpliﬁed approach” [CRR79] by J.C. Cox, S.A. Ross and M. Rubinstein. The Cox-Ross-Rubinstein market model (CRR model) is an example of a multi-period market model of the stock price.
