How it started

History

The AEX started from a base level of 100 index points on 3 January 1983 (a corresponding value of 45.378 is used for historic comparisons due to the adoption of the Euro). The index's peak to date was set on 26 October 2021 816.91 After the dot-com bubble in 1999, the index value more than halved over the following three years before recovering in line with most global financial markets.

The AEX index dealt with its second largest one-day loss on 12 March 2020, when the index closed down almost 11% during the coronavirus pandemic.

The AEX index enjoyed its third largest one-day loss on 29 September 2008, when the index closed down almost 9%. The decade between 1998 and 2008 was bad for the AEX index, as it was the worst performing stock index except for the OMX Iceland 15. The preceding years were a lot better compared to the rest of the world.
