The Externality of Foreign Investor Disclosure
A new study finds that daily disclosures of foreign investor holdings in China’s stock market, especially via the Stock-Connect program, spark herding among local retail investors. These investors view foreign traders as smart money and imitate their trades, causing short-term price swings and later reversals. The herding effect, amplified by media coverage, outweighs the direct impact of foreign capital. Inflated prices prompt Chinese firms to overinvest, reducing efficiency. The research highlights unintended consequences of market liberalization.
What it examines
This paper studies how daily public disclosure of foreign investor trades in China's retail-heavy stock market leads local investors to copy these trades, causing short-term price swings and later reversals. Using data analysis and path analysis, the study explores the effects on stock prices and company investment decisions.
What it concludes
The study finds that foreign investor disclosures trigger herding by local investors, amplifying price distortions and reducing investment efficiency in Chinese firms. These results warn that certain market liberalization policies can have negative side effects, suggesting regulators should carefully design disclosure rules. Applications include improving financial regulation and understanding retail investor behavior.
