The Black–Scholes equation is a parabolic partial differential equation, which describes the price of the option over time. The equation is: A key financial insight behind the equation is that one can perfectly hedge the option by buying and selling the underlying asset and the bank account asset (cash) in such a way as to "eliminate risk". This hedge, in turn, implies that the… In mathematical finance, the Black–Scholes equation is a partial differential equation (PDE) governing the price evolution of a European call or European put under the Black–Scholes model. Broadly speaking, the term may refer to a similar PDE that can be derived for a variety of options, or more generally, derivatives.
WebThis entry derives the Black-Scholes formula in martingale form. The portfolio process Vt representing a stock option will be shown to satisfy: Vt = e - r ( T - t) 𝔼ℚ[VT ∣ ℱt].
