strong-form market efficiency One of three categories of market efficiency defined by Eugene Fama. In a strong-form efficient market, it is impossible to achieve abnormal returns from the use of any information available in the market, be it public or available only to a restricted number of market participants. In general, markets are held not to be strong-form efficient, since it appears to be possible to make abnormal returns from insider dealing. Compare: semi-strong-form market efficiency, weak-form market efficiency.See: efficient markets hypothesis. |
