AEX Index

Introduction

The AEX Index is the Netherlands’ leading stock market benchmark and one of Europe’s most established equity indices. It tracks the 25 largest and most actively traded companies listed on Euronext Amsterdam, providing investors with a reliable measure of the Dutch equity market.

Although the Netherlands is a relatively small country, many AEX constituents are globally recognized companies with significant international operations, making the index an important indicator of both European and global business activity.

The History of the AEX Index

The AEX Index was launched in 1983 by the Amsterdam Stock Exchange, making it one of Europe’s longest-running modern equity benchmarks.

The composition is reviewed regularly to ensure it reflects the Dutch market’s leading companies.
