Market efficiencyThe notion of stock market efficiency, first introduced by Fama (1965), has played acentral role in both theoretical and empirical work on the reflection of information instock prices. As defined by Fama (1970), a stock market is efficient if prices alwaysfully reflect available information. Information is divided into three subsets,distinguishing between weak, semi-strong and strong form efficiency with respect tohistorical prices, publicly available information, and private information, respectively.A related strand of literature, reviewed in Verrecchia (2001), has dealt with thetheoretical modeling of how the disclosure of information affects investors as reflectedin stock prices and trading volume. One interesting insight from this literature is therevelation in Grossman and Stiglitz (1980) that prices can only fully reflect costlessinformation, since there must be a return to acquiring information at a cost, otherwisethere will be no information acquisition. This insight indeed led to a revised definitionof efficiency in Fama (1991), where two versions of the hypothesis that security pricesfully reflect all available information are given. The strong version stipulates thatinformation and trading costs are always zero, while the weaker version states thatprices should reflect information to the point where the marginal benefits of acting oninformation do not exceed the cost. As noted in Ball (1994) this in essence involves areclassification from the three earlier and more statistically-based information subsetsto subsets based on the cost of information. Empirical work has to a large extentsupported the efficiency hypothesis, although several anomalies have been uncovered(see the reviews by Fama (1991) and Kothari (2001)), e.g. the post announcement drift,which concerns the tendency for stock prices to continue to drift after informationdisclosures
