What Is Efficient Market Hypothesis? The Efficient Market Hypothesis (EMH) states that the stock asset prices indicate all relevant information very quickly and rationally. Such information is shared universally, making it impossible for investors to earn above-average returns consistently.

The efficient-market hypothesis (EMH) [a] is a hypothesis in financial economics that states that asset prices reflect all available information. A direct implication is that it is impossible to "beat the market" consistently on a risk-adjusted basis since market prices should only react to new information.

If this theory is true, nothing can give you an edge to outperform the market using different investing strategies and make excess profits compared to those who follow market indexes.
