Active managers have strong incentives to concurrently realize tax losses and window dress portfolios at the ends of calendar quarters. Consequently, stocks with capital losses experience downward price pressure, and a large share of returns to momentum strategies is earned at these times. This turn-of-the-quarter effect is absent prior to 1983, and is strong in big stocks afterward. Price pressure appears as: abnormal returns in factor model regressions, significant return responses in Fama-MacBeth cross-sectional regressions, and trends in cumulative abnormal daily returns. While price pressure in December creates return reversals in January, quarter-end price pressure continues into the following month.
