Abstract

This is a personal assessment of the intellectual contribution of the Black–Scholes model of option pricing. I argue that the real contribution of the paper is to show that European options can be replicated exactly if the future variability of the path of transaction prices is known. The continuous rebalancing and the probabilistic setting of the original paper mask this insight.
