The Relation Between Common Stock Returns Trading Activity and Market Value
研究普通股收益、交易活动与市场价值之间的关系，发现交易活动差异并非公司规模异常（不同规模公司股票风险调整收益的系统性差异）的根本原因。
ABSTRACT This study examines the relation between common stock returns, trading activity and market value. Our results indicate that although firm size and trading activity are highly correlated, differences in trading activity are not the underlying reason for the firm size anomaly, the finding of systematic differences in risk adjusted returns across stocks of firms of different size.
