In a risk-neutral world, the stock price dynamics is 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… small 90s house
