Market context — why this matters
Index inclusions and exclusions can trigger trading flows as index funds and ETFs trade to match the new constituent list.
Market observers and participants monitor these quarterly reviews closely.
That’s because reconstitution events can produce concentrated buying pressure for the added stocks.
They can also produce selling pressure for the removed stocks around the implementation dates.
For investors and allocators, that often means increased short-term volatility in the affected names.
Actionable considerations for investors, founders, and allocators
If you manage funds or run ETFs tied to onshore Chinese indices, plan for the following:
- Prepare trading schedules. Execute trades before the post-close implementation window if you want to avoid end-of-day liquidity squeeze.
- Monitor liquidity in added/removed names. Added constituents can see order book imbalances near implementation.
- Watch reserve list stocks. The reserve list is the next source of replacements until the next quarterly review.
- Communicate with stakeholders. Inform LPs, clients, or internal teams about potential tracking error or short-term price moves.
Quick recap
Effective at market open on Monday, September 22, 2025:
