Review AEX-Index family

The AEX-Index® family (AEX, AMX, AScX) is reviewed quarterly (March, June, September, December). The full annual review   will continue to be conducted in March. The June, September and December review serve to include new entrants in case the index consists of less then 25 constituents and to facilitate inclusion of top 15 ranking non- constituents, for example recently listed companies (IPO’s).

 Timing of the reviews are aligned with the expiry of index derivative contracts, and the reviews are therefore effective after the close of business on the third Friday of the respective month.
