random walk
Stochastic stepwise motion
A random walk is a path consisting of successive steps in random directions, used as a mathematical model in statistics, physics, and finance.
The concept captures how particles diffuse through liquids, how stock prices fluctuate, or how a drunk might stagger home—each step independent of the last, direction determined by chance.
The physicist modeled molecular movement as a random walk.
In finance, the random walk hypothesis suggests that stock prices are fundamentally unpredictable.
