From Wikipedia, the free encyclopedia The random walk hypothesis is a financial theory stating that stock market prices evolve according to a random walk (so price changes are random) and thus cannot be predicted.

Random walk patterns are also widely found elsewhere in nature, for example, in the phenomenon of Brownian motion that was first explained by Einstein. (Return to top of page.) It is difficult to tell whether the mean step size in a random walk is really zero, let alone estimate its precise value, merely by looking at the historical data sample.
