Quick Take: China's National Team—Missed the World Cup but Moved Markets
Another round of A-share intervention
- On July 19, members of the "Chinese National Team“—a group of state-backed investment funds—disclosed measures taken to stabilize the A-share market following a sharp selloff in AI and other technology stocks.
- Public reports indicate the measures largely involved purchases of broad equity ETFs and selected large-cap stocks, but the timing and composition of purchases were not disclosed.
Interventions may create temporary market distortions
- Interventions can create short-term distortions because their objective–in this case market stabilization–is not to align prices with fundamentals.
- Potential evidence of the intervention is large-cap outperformance during the month before the July 19 disclosures, when large-cap outperformed small-cap by 9.6% (top chart).
- Historically, similar reported interventions have been followed by reversals in large-cap outperformance (bottom chart).
Stay diversified; stay disciplined
- Rather than attempting to predict such interventions, we view them as episodic sources of relative price distortion.
- A disciplined, well-diversified investment process is well suited to withstand such episodes and to benefit as policy-driven distortions normalize.
