Fundamental anomalies and the size puzzle in China: A data mining approach

Abstract

The paper documents the profitable fundamental-based anomalies in China's A-share market and proposes the fundamental-related size puzzle which is converse to prior literature on the US stock market: these anomalies are systematically more pronounced among big stocks than among small stocks. Using the bootstrap approach to control for data mining, the fundamental-related size puzzle strengthens. Further evidence points to the widely perceived view about China's A-share market that for small stocks subject to severe shell-value fluctuations due to IPO constraints, fundamental information is less relevant and hardly incorporated into prices even upon earnings arrival.
