Granger Tests of Return and Volatility Links Between Chinese and US Stocks
Summary
This study examines how Chinese and US equity markets move together, with a focus on whether movements in one market help explain later movements in the other. It uses Granger causality tests on market returns and volatility, reporting evidence of two-way relationships in both measures. The historical record is described as mostly linked, though periods of divergence also occur.
The analysis also considers large daily US market moves and US trading during Chinese market holidays. Strong US gains are associated with a tendency for the China Securities Index to rise the next day, while large US declines have a stronger reported downside association. Holiday-period US performance is likewise linked to the direction of Chinese stocks after trading resumes. These are reported historical tendencies, not guarantees or a complete trading system; the supplied text omits the study period, detailed test specifications, and controls for other factors.
Key ideas
- Granger tests indicate that Chinese and US stock returns help explain one another.
- The study also reports two-way links between volatility in the two markets.
- Large US market declines are associated with stronger downside effects on subsequent Chinese trading than comparable gains are with upside effects.
- US market performance during Chinese holidays is reported to relate to Chinese market direction after reopening.
- The findings describe historical associations and do not establish reliable standalone trading signals.
