Suggested update

The Composition table, listing members of the AEX is 3 years out of date, so can that please be updated? The current information can be found here: https://www.euronext.com/sites/www.euronext.com/files/aex_20150930.pdf Disclosure - I work in the communications team at RELX Group (formerly Reed Elsevier) so I'm assuming it's best if I don't make this update myself? Thanks Ryoba (talk) 12:10, 1 December 2015 (UTC)[reply]

This page doesn't seem to be getting much interest, so I've gone ahead and updated the table as mentioned above.Ryoba (talk) 11:09, 4 December 2015 (UTC)[reply]

Official name

The official, trade-marked name of the index is AEX index. It is NOT an abbreviation of Amsterdam Exchange Index, though is of course derived from this. Compare ABN AMRO vs Algemene Bank Nederland Amsterdam Rotterdam bank. See Euronext's website for definitions etc. DocendoDiscimus 11:07, 13 September 2005 (UTC)[reply]

Calculation

Is there a financial expert who could reword the Calculation section? To my mind, its meaning isn't clear. The formula, as it now stands, seems somewhat recursive: The index value seems to be calculated by a formula that includes itself. Could the calculation section be expanded upon slightly, to make it a little clearer? Trafford09 (talk) 07:05, 5 May 2010 (UTC)[reply]

I wrote the section originally some time ago. Re-reading it now, I don't see exactly what is unclear about it: the index value at any given time is given by summing the individual products of each stock price and the no. of shares it has in the AEX basket, then dividing by 100. In other words the index value I(t) is given by:

I(t)={\frac {\sum _{i=1}^{N}(P_{i}(t)\times \,S_{i}\,)}{100}}

with N the number of companies in the index (nominally 25), P(t) the share price of company i and S the number of shares of company i in the basket. I'll put the formula into the page but I'm not sure how the calc. can be described any more simply than that. ~~The formula isn't recursive.~~ Gr1st (talk) 20:24, 5 May 2010 (UTC)[reply]

The formula is recursive in the sense that the number of shares which each company gets in the basket S (when it is adjusted each year or after an exceptional event) is based on its share price at the review date. S does not change on a day-to-day basis, though; the only parameter in the calc. which does is the share price. The index value is not included in the calculation formula.

Thanks very much for the swift & well-displayed formula, Gr1st. Like that it now makes sense to me (guess it should have, before!). Cheers, Trafford09 (talk) 20:42, 5 May 2010 (UTC)[reply]

No probs. I do agree that it is much clearer displayed as a formula, which is probably what I should have done in the first place. The official index rules (just updated the dead link to them) simply describe the calc in words; I obviously couldn't be bothered expanding on that. Gr1st (talk) 20:58, 5 May 2010 (UTC)[reply]

Remove the KLM plane?

KLM is not mentioned anywhere on the page. — Preceding unsigned comment added by 217.122.119.208 (talk) 08:01, 12 April 2016 (UTC)[reply]

Creation of new category

If we look at Category:Companies by stock market index, most of the world's major indices are listed, except for the AEX. Can somebody add this? 92.71.60.62 (talk) 12:25, 6 November 2023 (UTC)[reply]
