Using a proprietary dataset from 2016 to 2019, we find that order flows from foreign investors, facilitated by regulatory liberalization through several channels, present strong predictive power for future stock returns in the Chinese market. Most surprisingly, foreign investors possess the ability to process local firm-level public news, whereas their informational advantages regarding global market-level information are relatively muted. Further, the predictive power of foreign investors is particularly strong on large price movement days when the implications of firm-level information is likely most pronounced. Finally, regulatory reforms that generally relax investment access requirements further improve foreign investors’ predictive power

Using the introduction of margin trading in China, this study examines the effects of margin trading on the informativeness of trades and stock market liquidity. Using the methodology of Hasbrouck (1991 and 1993), I find that allowing investors to trade on margin leads to more informed trading. This increase in informed trading is mirrored by an increase in the adverse selection component of the bid-ask spread and a decrease in the relative weight placed on public information in trading decision. The discussed findings are more pronounced for stocks with relatively high levels of margin trading. Overall, the findings in the paper suggest that margin trading may lead to more information-based trading and lower levels of stock market liquidity.

This paper documents different timeliness in disseminating sanction and enforcement information (SEI) by two types of regulatory agencies in China and the different consequences that flow from them. The China Securities Regulatory Commission (CSRC) does not make timely public disclosures of SEI and, instead, leave it up to the firms to make a public announcement under their general obligation to disclose price-sensitive information. The firms therefore have considerable discretion in deciding whether and when to disclose SEI. In contrast, the stock exchanges in Shenzhen and Shanghai make SEI public promptly through the media and the exchanges’ official websites. Using Chinese SEI data during the period 1999 to 2005, we find that the CSRC approach is associated with significantly lagged corporate disclosure (compared with the timely stock exchange approach) and a significantly negative (but delayed) stock price reaction. We also show that the sanctioned firm may take advantage of the less timely CSRC approach to delay its disclosure of SEI for opportunistic reasons such as completing material transactions. We conclude that the CSRC should make immediate public announcements of SEI as these contain price-sensitive information. Furthermore, the immediate dissemination of SEI will bring the CSRC into line with the disclosure practices of China’s stock exchanges and international market regulators.
