Weak Form Efficiency(redirected from Weak Form of the EMT)
Weak Form Efficiency
A version of the efficient markets theory on how markets work. It holds that the market efficiently deals with most information on a given security and reflects it in the price immediately. Specifically, weak form efficiency states that technical analysis is ineffective and that prices are on a random walk. Investors and academics disagree on how well the model works, but it is less controversial than the semi-strong form of the EMT and the strong form of the EMT.
