When a financial problem can be expressed as a PDE (like the Black-Scholes equation), FDM is often the numerical method of choice. It discretizes the continuous time and asset price space into a grid.
Asset prices do not move in smooth, predictable lines. They exhibit randomness, known in mathematics as stochastic behavior. Financial models use stochastic differential equations (SDEs) to simulate asset trajectories over time. mathematical modeling and computation in finance pdf

Beyond simple Brownian motion, stochastic volatility models (like the Heston model) are necessary to capture the "volatility smile" observed in option markets. 3. Computational Methods: Solving the Models
