Euronext today announced the results of the September 2025 review for the AEX®, AMX®, AScX® and AEX® ESG. The September review is an additional annual review, the results of which will be implemented after markets close on Friday 19 September 2025 and will be effective from Monday 22 September 2025.
The results of the September 2025 review mark the first implementation of the changes in the methodology and composition of the AEX Index Family, as announced on 11 March 2025, with five new constituents added to the AEX index. The change in methodology, including the increased number of constituents in the AEX, is designed to better reflect local market structure, and to enhance the relevance and investability of the AEX index family.
In addition, the AScX® index has been rebranded to AMS Next 20® effective from this review, reflecting its updated positioning. The number of constituents has been decreased from 25 to 20 companies. The index will follow the same review schedule as the AEX® Family.
The full details on the composition and methodology for the AEX® Index Family can be found at:
