Abstract This article develops a flexible binomial model with a “tilt” parameter that alters the shape and span of the binomial tree. /Filter /FlateDecode . The result trinomial model converges to true option values quicker than that of binomial model. About this page. As later discussed in Broadie and Detemple (1996) that trinomial model dominate binomial model in terms of both speed and accuracy. The general formulation of a stock price process that follows the binomial is shown in figure 5.3. . 3p~b 1P�Q���r6��h` f�O endstream endobj 438 0 obj <> endobj 439 0 obj <> endobj 440 0 obj <>stream [my xls is here https://trtl.bz/2AruFiH] The binomial option pricing model needs: 1.

Backward induction: Starting at expiry, we know the payff of the call: 3.2 at (A), 0 at (B), 0 at (C). For some types of options, such as the American options, using an iterative model is the only choice since there is no known closed-form solution that predicts price over time.
