This paper presents evidence regarding the post-earnings announcement drift (PEAD) anomaly for the Greek market in the years 2000–2006 (covering earnings announcements in the years 2001–2007). The impact of the introduction of International Financial Reporting Standards on the size and prevalence of the PEAD anomaly is examined. Unlike recent evidence for the US market we find PEAD to be alive and well, and of growing importance in our Greek sample. It may be the adoption of international financial reporting standards (IFRS) has served to reduce earnings predictability in Greece and thus enhance PEAD in the Athens stock exchange (ASE) market. This contrasts strongly with US evidence that the post-earnings-announcement drift anomaly is now waning as more efficient markets and smarter, fundamentals-based, traders arbitrage its impact on stock prices.

AbstractIn this paper I assess the presence of post‐announcement drifts associated with dividend changes after controlling for earnings surprises. All quarterly cash dividend changes announced by firms listed on the New York Stock Exchange (NYSE) and American Stock Exchange (AMEX) from 1974 through 1989 are examined. The results show that significant post‐announcement drifts associated with dividend changes are present after controlling for earnings surprises. However, the results are not conclusive on whether the market fully incorporates the simple time‐series properties of dividends.

This article investigates the post-announcement drift (PAD) of stock returns in the Chinese stock market. We use a sample of voluntary trading disclosures to test the hypothesis that an asymmetric PAD exists in a market in which managers are more likely to suppress negative news. We show that a pattern of short-term momentum and long-term reversal in returns persists for up to 250 trading days following the announcement of trading statements in the Chinese stock market. This finding is stronger for positive announcements in terms of the magnitude and the variance of stock returns. Our findings are in line with both Shin's theoretical predictions and the credibility hypothesis, in which disclosure and asset returns are jointly determined and the adoption of a "sanitisation strategy" in information disclosure generates more volatile returns for firms issuing good news. Further, we show that the latter effect is more pronounced for firms which are partially state-owned, suggesting that they potentially receive more government support, a finding which is in line with the hypothesis that the incentive to suppress negative information is related to a country's legal/judicial system.
