Trading volume for winners and losers on the Tokyo Stock Exchange

This paper examines trading volume on the Tokyo Stock Exchange. Traditional theory suggests that taxes create strong incentives to delay realization of capital gains and accelerate realization of losses. Contrary to the theory, we find strong evidence that turnover is higher for stocks with gains (winners) than for stocks with losses (losers). In particular, the winner stocks of keiretsu firms tend to have high end-of-fiscal-year turnover. This is true even when realizing gains could result in higher tax liabilities. We conclude that capital gains taxes have only a small impact on turnover in Japan. Other non-tax-related motives, especially window dressing, appear to dominate investor behavior. We find strong evidence that this window dressing is concentrated in the stock of keiretsu firms.
