Small Firm Effect

Small Firm Effect

A theory stating that publicly-traded companies with low market capitalization tend to outperform larger ones. Part of the small firm effect may be explained by the fact that these firms are riskier and, therefore, have higher returns. Additionally, small firms have lower stock prices and, thus, what would be a small price appreciation for a large firm can, in fact, be huge for a small firm. See also: Neglected-firm effect.
