In general, as the number and sophistication of participants within a market increase, the market becomes more efficient. The informationally efficient market theory moves beyond the definition of the well-known efficient market hypothesis, previously developed by Fama. Informational efficiency is a natural consequence of competition, few barriers to entry, and low costs of obtaining and publishing information, according to Fama’s “Efficient Capital Markets: a Review of Theory and Empirical Work.”. This form of efficiency believes that there is no way to earn excess returns based on both public and private information.

Another lesson: accounting tricks don't fool anybody. In 1970, in "Efficient Capital Markets: a Review of Theory and Empirical Work," Eugene F. Fama defined a market to be "informationally efficient" if prices at each moment incorporate all available information about future values. The market is said to be efficient if it rapidly and completely impounds all relevant information into asset prices. Not even insider information .

Another capital market hypothesis is a semi-strong form of efficiency, where the current price of securities is fully affected by all past information and all publicly available information. There must be subtle shades of semi-strong market efficiency, but they are not typically differentiated. This means that strong form efficiency is not realistic in capital markets. This theory believes that it is impossible for investors to beat the market consistently on a risk adjusted basis because stock price only reacts to new information and changes in discount rates. In other words, quality of financial information should be one of the most important inputs in decisionmaking regarding - capital allocation, that is investments.

The informational efficiency of financial markets determines the ability of investors to "beat" the market and earn excess (or abnormal) returns on their investments. Strong form Efficiency: Strong form efficiency implies that all relevant information including those which are only available to those in privileged positions are fully reflected in share prices. Efficiency as it relates to capital markets occurs when share prices at all times reflect all available relevant information. When these insiders violate the law by trading on this private information, they may make money. Since past prices are deemed public information, weak form efficiency implies semi-strong form efficiency and semi-strong form efficiency implies strong form efficiency. It reflects all information, both public and private. In recent times, passive funds, such as Fidelity and Vanguard, have witnessed a large inflow of funds from active managers, who are struggling to generate returns for their investors. Market operational efficiency focuses on bringing buyers and sellers together at the lowest possible cost. Modern capital markets do all the things discussed above, and at low cost.
