Weak efficiency - This type of EMH claims that all past prices of a stock are reflected in today's stock price. Therefore, technical analysis cannot be used to predict and beat the market.

Semi-strong efficiency - This form of EMH implies all public (but not non-public) information is calculated into a stock's current share price. Neither fundamental nor technical analysis can be used to achieve superior gains.

Strong form version of the efficient market hypothesis states that all information—both the information available to the public and any information not publicly known—is completely accounted for in current stock prices, and there is no type of information that can give an investor an advantage on the market.
