"Three levels of Market Efficiency I. Weak form - prices reflect all security-market information - Current prices reflect all security-market information, including the historical sequence of prices, rates of return, trading volume data, and other market-generated information - This implies that past rates of return and other market data should have no relationship with future rates of return - Technical analysis, which relies on the past history of prices, is of little or no value in assessing future changes in price II. Semi strong form - prices reflect all public information - Current security prices reflect all public information such as earnings, stock and cash dividends, splits, mergers and takeovers, interest rate changes etc. It also says that prices adjust to such information quickly and accurately so abnormal profits on a consistent basis can not be earned. - This implies that decisions made on new information after it is public should not lead to above-average risk-adjusted profits from those transactions III. Strong form - prices reflect all public and private information - Stock prices fully reflect all information from public and private sources - This implies that no group of investors should be able to consistently derive above-average risk-adjusted rates of return - This assumes perfect markets in which all information is cost-free and available to everyone at the same time.
