Abstract
In this paper, we present an application of stochastic calculus to show “ the robustness of the Black-Scholes formula”. The Black-Scholes formula is extensively used in order to determine the price of financial products called options. This formula is valid only when the parameters (which can, in general, be stochastic and time-dependent) are constant or deterministic. When this is not the case, this formula is still used by means of an approximation at time t of these parameters, without theoretical justification. We prove in this paper that this methodology is correct in some sense.
