The efficient-market hypothesis (EMH) is a hypothesis in financial economics that states that asset prices reflect all available information. This is kind of complicated. Which of the following phenomena would be either consistent with or a violation of the efficient market hypothesis? Fama’s results reported in 1965 were entirely empirical in nature, but the coincident work by Samuelson (1965) provided a strong theoretical basis for this hypothesis. Outline various versions of Efficient Market Hypotheses. The logic of the random walk idea is that if the flow of information is unimpeded and Definition.

The EMH is generally understood as the argument that the markets are informationally efficient as the value of the assets traded reflects all existing information, and that investors are analyzing this information in a rational way in order to lead to optimal outcomes.
