Report interpretation
Overview
Goldman Sachs reviews FTSE Russell’s September 2026 quarterly changes to the FTSE China 50 and FTSE China A50 and assesses the associated index characteristics, sector weight changes, estimated passive flows and historical trading patterns around implementation.
Core views
FTSE Russell announced its quarterly FTSE China Index Series review after the September 2 market close, with all changes taking effect after the September 18 close. In FTSE China 50, Hua Hong Semi (H) (1347) and Montage Technology (H) (6809) will replace Kuaishou Technology (B) (1024) and S.F. Holding (H) (6936). In FTSE China A50, Shengyi Technology (A) (600183) and Adv. Micro-Fabri. Equip. (A) (688012) will replace Wanhua Chemical (A) (600309) and Muyuan Foods (A) (002714). The weight rebalanced is about 3.4% for China 50 and 3.3% for China A50. The report expects the new composition to modestly change index fundamentals. For FTSE China 50, forward 12-month P/E rises from 9.0x to 9.1x, trailing dividend yield remains 3.4%, and 2026-27 EPS CAGR increases from 10.0% to 10.7%. For China A50, forward P/E rises from 11.7x to 12.1x, dividend yield declines from 2.7% to 2.6%, and 2026-27 EPS growth edges up from 18.1% to 18.2%. The changes therefore increase the indices’ technology exposure and growth profile, while producing only limited changes in income yield. Goldman Sachs estimates that the combined FTSE China and potential FTSE Global Equity Index Series effects could create more than US$1.9bn of gross two-way passive flows for China: US$1.256bn for China 50 and US$633mn for China A50. Tech Hardware & Semis is expected to receive the largest net inflow, about US$442mn in the sector table and described as roughly US$450mn in the report. Banks face the largest estimated net outflow, about US$542mn in the table and roughly US$550mn in the text. Consumer Staples and Chemicals & Other Materials are also expected to experience notable net selling, at about US$106mn and US$103mn respectively. The flow estimates incorporate both FTSE China and global-index rebalancing effects. On trading behavior, the report distinguishes current positioning from historical patterns. Current FTSE China 50 additions have outperformed deletions amid elevated volatility, but the historical five-year pattern indicates volatile and mildly negative relative performance around or after the effective date. For FTSE China A50, additions are currently flat relative to deletions after an earlier gain three weeks before the announcement was erased by a sharp drawdown. Historically, A50 additions versus deletions have tended to reverse after announcement and then recover around the effective date. The report therefore frames the implementation window as flow-sensitive but not directionally uniform across the two indices.
Analysis framework
The report starts with the announced constituent changes and implementation date, then compares current and pro forma index weights, valuation, dividend yield and earnings-growth metrics. It estimates passive buying and selling from FTSE China and FTSE GEIS rebalancing, aggregates those effects by sector, and compares additions’ and deletions’ relative returns around historical rebalances over the past five years.
Methodology notes
Index rebalancing flow and weight analysis
The report links constituent and sector weight changes to estimated passive buying and selling, separating composition effects from the trading flows expected around implementation.
Historical additions-versus-deletions performance around index review announcements and effective dates
The report compares relative performance before and after prior FTSE China 50/A50 rebalance announcements to characterize likely event-window trading behavior.
Forward 12-month P/E comparison of current and pro forma index composition
Forward P/E is used to show how the revised constituents change the indices’ aggregate valuation profile.

Impact & implications
The report indicates that the rebalance shifts passive-flow support toward technology hardware and semiconductor exposure while creating the strongest estimated selling pressure in banks and additional outflows in consumer staples and chemicals. Historical evidence suggests that announcement-to-effective-date trading can be volatile and may reverse, particularly for China A50 additions relative to deletions.
What to watch
- Implementation of the constituent changes after the September 18, 2026 market close.
- Whether estimated passive flows into Tech Hardware & Semis and out of Banks, Consumer Staples and Chemicals materialize.
- Relative performance of additions versus deletions as the effective date approaches and passes.
