Why is price momentum absent in China? Since momentum is commonly considered arising from investors’ under-reaction to fundamental news, we decompose monthly stock returns into news- and non-news-driven components and document a news day return continuation along with an offsetting non-news day reversal in China. The non-news day reversal is particularly strong for stocks with high retail ownership, relatively less recent positive news articles, and limits to arbitrage. Evidence on order imbalance suggests that stock returns overshoot on news days due to retail investors' excessive attention-driven buying demands, and mispricing gets corrected by institutional investors on subsequent non-news days. To avoid this tug-of-war in stock price, we use a signal that directly captures the recent news performance and re-document a momentum-like underreaction to fundamental news in China.

This paper examines whether foreign investor heterogeneity plays a role in stock liquidity on a sample of 27,976 firms from 39 countries for the period from 2003 to 2009. Results show that foreign direct ownership is negatively, while foreign portfolio ownership is positively, associated with various measures of stock liquidity. Furthermore, liquidity also reduces more (less) in firms with larger foreign direct investment FDI (foreign portfolio investment, FPI) during the 2008 market downturn. As predicted by finance theory, foreign investors influence stock liquidity through both trading activity and information channels. Our findings also indicate that the presence of FDI investors improves firm valuation and operating performance even at the expense of an increase in the firm’s cost of capital, suggesting that the value-enhancing benefits from FDI investors’ monitoring efforts outweigh the liquidity costs and high adverse selection premium demanded by less informed investors. In contrast, the positive impacts of FPI ownership on firm performance, as previously documented in existing literature, becomes negative and also not robustly significant after controlling for liquidity.
