• ATI (USA)

For the MSCI Emerging Markets Index, the largest additions by market capitalization include:

Bangladesh Index Pause

MSCI confirmed it will not implement any changes for securities classified in Bangladesh for the MSCI Bangladesh Indexes or impacted composite indexes during this review. Implementation of index review changes and corporate events for these indexes will resume starting from the November 2026 Index Review.

What the Numbers Show

The net reduction of 37 securities in the MSCI ACWI Index (92 deletions vs 55 additions) suggests a tightening of inclusion criteria or a shift in market capitalization thresholds that excludes more constituents than it admits in this cycle. Meanwhile, the Small Cap index saw a larger net outflow of 58 securities (261 deletions vs 203 additions), indicating significant churn in the smaller end of the market spectrum.
