# Brownian Motion ⎊ Area ⎊ Greeks.live --- ## What is the Concept of Brownian Motion? Brownian motion, also known as a Wiener process, is a continuous-time stochastic process often used to model the random movement of particles in a fluid. In quantitative finance, it serves as a fundamental building block for modeling asset prices, assuming that price changes are continuous, random, and independent over time. This mathematical construct forms the basis for many option pricing models, including the Black-Scholes framework. The process exhibits independent increments and normally distributed changes. ## What is the Application of Brownian Motion? Financial models frequently employ geometric Brownian motion to describe the evolution of asset prices, suggesting that logarithmic returns are normally distributed. This assumption underpins the valuation of various derivatives, as it allows for the calculation of future price probabilities. For instance, in simulating future paths for cryptocurrencies, Brownian motion can generate a range of potential outcomes, aiding in risk assessment and scenario analysis for options portfolios. It provides a tractable mathematical framework for price dynamics. ## What is the Limitation of Brownian Motion? Despite its widespread use, Brownian motion has limitations when applied to real financial markets, especially cryptocurrencies. It struggles to capture phenomena like sudden price jumps, fat tails in return distributions, and time-varying volatility, which are characteristic of crypto assets. Real market prices often exhibit non-normal distributions and periods of high volatility clustering, which the standard Brownian motion model does not account for. Therefore, advanced models often incorporate jump components or stochastic volatility to better reflect market realities. --- ## [Monte Carlo Pricing](https://term.greeks.live/definition/monte-carlo-pricing/) Computational simulation method to estimate derivative fair value through thousands of potential future price paths. ⎊ Definition ##
