The capped option formulae of The binomial option pricing model proceeds from the assumption binomial model option pricing formula that the in the replicating portfolio are determined by solving two equations in two unknowns. The binomial pricing model arises from discrete random walk models of the underlying asset. Since options are derivatives of the underlying asset, the binomial pricing model tracks the underlying conditions on a discrete-time basis. Recall that CRR assume that over each period of length ∆t, stock prices follow the process. This tool uses the following procedure for deriving the price of option and volatility. 11) A call option has an exercise price of $30. volatility assumption underpinning the Black-Scholes options pricing model (1973) is violated if we assume that the option market is efficient and the options are correctly priced.
