Eugene Fama developed a framework of market efficiency that laid
out three forms of efficiency: weak, semi-strong, and strong. Each
form is defined with respect to the available information that is
reflected in prices. Investors trading on available information
that is not priced into the market would earn abnormal returns,
defined as excess risk-adjusted returns.
Weak Form
In the weak-form efficient market hypothesis, all historical
prices of securities have already been reflected in the market
prices of securities. In other words, technicians – those trading
on analysis of historical trading information – should earn no
abnormal returns. Research has shown that this is likely the case
in developed markets, but less developed markets may still offer
the opportunity to profit from technical analysis.
Semi-strong Form
In a semi-strong-form efficient market, prices reflect all
publicly known and available information, including all historical
price information. Under this assumption, analyzing any public
financial disclosures made by a company to determine a stock’s
intrinsic value would be futile since every detail would be taken
into account in the stock’s market price. Similarly, an investor
could not earn consistent abnormal returns by acting on surprise
announcements since the market would quickly react to the new
information.
Strong Form
In a strong-form efficient market, security prices fully reflect
both public and private information. Therefore, insiders could not
generate abnormal returns by trading on private information because
it would already figure into market prices. However, researchers
find that markets are generally not strong-form efficient as
abnormal profits can be earned when nonpublic information is
used.
