The Netherlands AEX 25 Index: A Brief History

The AEX index, derived from the Amsterdam Exchange index, serves as a key indicator for the Dutch stock market. Comprising of prominent Dutch companies trading on Euronext Amsterdam, formerly the Amsterdam Stock Exchange, this index encapsulates the nation's economic pulse.

Here we delve into the history, components, and intriguing aspects of the Netherlands AEX 25 Index.


This index currently comprises 25 of the most actively traded securities from Euronext Amsterdam. It assumes a pivotal role within Euronext, a consortium of stock exchanges across Europe, which also encompasses notable indices like BEL20 (Euronext Brussels), ISEQ 20 (Euronext Dublin), PSI-20 (Euronext Lisbon), OBX Index (Oslo Børs), and CAC 40 (Euronext Paris).

When did the Netherlands AEX 25 Index start trading?

The roots of the AEX 25 Index go way back to March 1983 when it was first introduced with a base level of 100. At its inception, it featured a selection of 13 prominent Dutch companies. This initial lineup included renowned names like Royal Dutch Shell and Unilever.

The index aimed to provide investors with a comprehensive overview of the Dutch stock market's performance.

The ‘90s Growth

The 1990s marked a period of substantial growth for the AEX Index. It expanded both in terms of the number of constituent companies and its overall value.

The index diversified across a number of different sectors, represented by not only traditional industries, but also newer industries such as technology, finance, and telecommunications. This diversification played a pivotal role in increasing the index's recognition through the wider investment world.

The 2000s Dot-com Bubble

The turn of the millennium brought about a significant challenge for the AEX Index. The burst of the dot-com bubble in the early 2000s led to a sharp decline in the index's value, losing over half its value over the following three years.

However, the Dutch economy demonstrated resilience, and over time, the AEX Index rebounded. This recovery was indicative of the nation's ability to navigate economic turbulence.

The 2008 Financial Crisis

The global financial crisis of 2008 left no country untouched, and the Netherlands was no exception. The AEX Index witnessed a substantial decline during this period, reflecting the widespread market turmoil.

The most significant drop occurred on 29 September 2008, with a nearly 9% decline.

The crisis prompted regulators and market participants to reevaluate their risk management strategies. The index was adjusted to include new eligibility criteria, enhancing its stability and reliability.

The Digital Age

The present-day AEX Index captures the Netherlands' ongoing transformation into a digital economy. Companies at the forefront of technological innovation, including those in the fields of e-commerce, fintech, and renewable energy, have found representation within the index.

This adaptation mirrors the nation's commitment to remaining competitive in an increasingly digital world.

Despite that, the index’s journey hasn't been smooth sailing. On 12 March 2020, during the throes of the coronavirus pandemic, the AEX index encountered its second-largest single-day loss, plummeting nearly 11%.

However, the index rebounded and reached its pinnacle on 26 October 2021, soaring to 816.91 points.

The Netherlands AEX 25 Index embodies the Dutch economy's fluctuations, resilience, and growth. From its origins in 1983, through a range of challenges and significant milestones, this index serves as a window into the dynamic world of Dutch commerce, reflecting both its struggles and triumphs.
