In this paper, we present an index option pricing equation that is theoretically superior to prior models. Specially, we develop an analytic index option pricing equation assuming each security underlying the index follows geometric Brownian motion. We compare our model to the standard index option pricing model based on the Black and Scholes formula and find the difference to be significant.
