Direct Answer
The Euronext 100 is a rule-based measurement of the 100 largest and most liquid equities listed on Euronext markets across Europe, maintained by Euronext. Like every index it owns nothing: it is a number produced by applying a published weighting formula to a selected list of securities, revised on a schedule the provider sets.
What this index covers
The Euronext 100 covers the 100 largest and most liquid equities listed on Euronext markets across Europe. Euronext defines which securities are eligible, how they are selected from that pool, and how much each one contributes to the published number.
The methodology document, published by Euronext, sets the rules for inclusion and removal. Corporate actions, index reviews, and eligibility changes all move the constituent list on the timetable the provider specifies.
How constituents are weighted
Swoopr has not verified the weighting method for this index against Euronext's current methodology document, so none is stated here rather than guessed. The provider link below is authoritative.
Current Euronext 100 constituents
Euronext publishes and licenses the Euronext 100 constituent list. Swoopr does not republish it here. The provider's own page is the authoritative source for current membership and weights.
