A »The three forms of market efficiency are: weak, semi-strong, and strong. Weak form efficiency states that past market data is reflected in current prices.

Strong form efficiency claims that all information, public and private, is reflected in prices, making it impossible to consistently achieve abnormal returns.

A »Market efficiency has three forms: weak, semi-strong, and strong. Weak form suggests all past prices are reflected in stock prices, making technical analysis ineffective.

A »Market efficiency has three forms: weak, semi-strong, and strong. Weak form asserts that past prices don't predict future prices; semi-strong form claims all public information is reflected in prices, rendering fundamental analysis ineffective; strong form suggests all information, public and private, is priced in, making insider trading unprofitable. For example, in a semi-strong efficient market, a company's earnings announcement would immediately adjust its stock price.
