The Efficient Market Hypothesis is a hypothesis in financial economics that states that asset prices reflect all available information.
A direct implication of the EMH is that it is impossible to "beat the market" consistently on a risk-adjusted basis since market prices should only react to new information. Developed independently by Samuelson and Fama in the 1960s, the EMH has become a holy grail for investors and academics alike.

I did my undergrad thesis on why the Efficient Market Hypothesis was wrong, but it wasn't nearly as funny as this.
