Evidence and Implications of Increases in Trading Volume Around Exchange Listings
Posted: 10 Aug 2001
After controlling for market volume trends and differences in volume measurement between the Nasdaq and the exchanges, we find that mean trading volumes increase significantly for Nasdaq stocks that list on the Amex or the NYSE. Furthermore, stocks with low (high) pre-listing volume tend to realize the largest volume increases (decreases) as well as the best (worst) post-listing performance. Our results support the hypothesis that stocks with high past trading volumes tend to experience lower future returns, and shed new light on the nature and possible causes of poor post-listing stock performance.
