Extreme Return-Volume Dependence in East-Asian Stock Markets: A Copula Approach

A copula approach is adopted to examine the extreme return-volume relationship in six emerging East-Asian equity markets. The empirical results indicate that the return-volume dependence is significant and asymmetric at extremes for all six East-Asian markets. In particular extremely high returns (large gains) tend to be associated with extremely large trading volumes, but only marginal (extremely small) returns tend to be related to either large or small volumes.
