Closed-Form Equations and Binomial Convergence

CLOSED-FORM EQUATIONS AND BINOMIAL CONVERGENCE
A very interesting stability and convergence test can be performed on binomial lattices. In calculating the value of a European call option, the Black-Scholes model can be used. In addition, a binomial lattice also can be used to estimate the option value. Because the binomial lattice in the limit approaches the closed-form Black-Scholes model for a simple European call option, the higher the number of steps, the closer the results. In addition, because a binomial lattice is simply a discrete simulation of closed-form continuous models, how consistent, reliable, and stable are the results? This is a valid question because simulations do not always provide exact results as, by definition, simulations provide randomly assigned inputs and the outputs that may change from trial to trial.
To answer the question of stability, the Black-Scholes model is used, together with binomial lattices using 5, 50, 100, and 500 steps. Each model is then simulated 10,000 times using Crystal Ball Monte Carlo simulation software. Table 6.6 shows that the binomial lattice is indeed highly consistent, reliable, and stable, and that results from a binomial lattice are replicable.
