Understanding Random Walk: A Legal Perspective on Market Theory

Definition & Meaning

A random walk is a financial theory that suggests stock prices move in unpredictable ways, similar to a series of random steps. This theory posits that market prices reflect all available information, which is incorporated into stock values as new data emerges. Consequently, the future price movements of stocks cannot be accurately predicted based on past performance.
