This study examines the relationship between trading volume and stock returns. The sample of the study consists of 266 stocks traded at the Colombo Stock Exchange (CSE) from 2000-2008. This study follows the conventional methodology used by Jagadeesh and Titman (Jagadeesh and Titman, 1993). The study revealed that stock returns are positively related to the contemporary change in trading volume. Further, it was found that past trading volume change is negatively related to stock returns. Investor misspecification about future earnings or illiquidity of low volume stocks can be the reason for the negative relationship between trading volume and stock returns.
