Weak form stock market efficiency

Weak form efficiency claims that past price movements, volume and earnings data do not affect a stock’s price and can’t be used to predict its future direction. Weak form efficiency is one of the three different degrees of efficient market hypothesis (EMH).

In particular, the theory claims that day-to-day stock prices are independent of each other, meaning that price "momentum" does not generally exist and past earnings growth does not predict future growth.
