Volume and Autocovariances in Short-Horizon Individual Security Returns
This article tests for the relations between trading volume and subsequent returns patterns in individual securities' short-horizon returns that are suggested by such articles as L. Blume, D. Easley, and M. O'Hara (1994) and J. Y. Campbell, S. J. Grossman, and J. Wang (1993). Using a variant of B. Lehmann's (1990) contrarian trading strategy, the authors find strong evidence of a relation between trading activity and subsequent autocovariances in weekly returns. Specifically, high-transaction securities experience price reversals, while the returns of low-transactions securities are positively autocovarying. Overall, information on trading activity appears to be an important predictor of the returns of individual securities. Copyright 1994 by American Finance Association.
