Stochastic Processes & Finance

From Brownian motion to option pricing — where math meets markets.

Read in Chinese →

Studying stochastic processes, I kept seeing how naturally they connect to markets — prices themselves can be modeled as stochastic processes.

Key Ideas

  • Brownian motion: continuous-time randomness
  • Martingales: fair-game math at the heart of option pricing
  • Itô’s lemma: the chain rule for stochastic calculus

A single post can belong to both “math” and “finance” — that’s exactly why this taxonomy exists.
