This page pictures the ETF’s basket, not the index. Because the fund uses optimised replication, portfolio changes reflect how the replication is implemented and do not necessarily coincide with the official index reviews.

Issuer-declared basket snapshots, compared by Rebalix. Each section states its own dates: the basket comparison uses the issuer file dates; top 10, composition and breakdowns the dates of the two archived snapshots; maturities, ratings and duration the monthly registry snapshots. Weight changes are shown above ±0.25 points (the archive records them from ±0.1). We record the past: nothing on this page is a recommendation.
