Abnormal Accrual, Informed Trader, and Long-Term Stock Return: Evidence from Japan

This study examines the association among abnormal accruals, long-term stock returns, and probability of informed trading. Some analytical and empirical research for postearnings announcement drift provide evidence that a high arrival rate of informed traders helps stock prices become more efficient. We focus on the abnormal accrual anomaly, and investigate these studies' implications using data from the Tokyo Stock Exchange in Japan. Consistent with these studies, we show that stocks with a high probability of informed trading exhibit less abnormal accrual mispricing relative to stocks with a low probability of informed trading.
