About AEX
The AEX tracks the 25 most actively traded securities on Euronext Amsterdam and dates back to 1983, making it one of Europe's older national indices. Despite its small constituent count it hosts several global heavyweights, including semiconductor-equipment leader ASML, which gives the index a pronounced technology tilt. Constituents are reviewed annually in March with interim quarterly adjustments.

History & Index Methodology
AEX is calculated in real time from the prices of its constituent stocks, typically weighted by free-float market capitalisation so that larger, more liquid companies carry more influence. The constituent list is reviewed periodically by the index provider, with companies added or removed based on size, liquidity and listing criteria. Long-run index history lets analysts compare today's level against decades of market cycles.

How to Read AEX
Watch AEX's level against its previous close for the day's direction, and against the 50-day and 200-day moving averages for the medium-term trend. A print near the top of the 52-week range with rising volume is often read as momentum by market participants, while repeated failures at the same level mark resistance. Breadth — how many constituents rise versus fall — shows whether a move is broad-based or driven by a few heavyweights.
52-week range: 896.27 – 1,124.13. Trailing 12-month change: 22.92%.
