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.
Basket
Source: basket file published by the issuer, as of 20 Aug and 31 Aug, compared holding by holding by Rebalix (cash excluded, lines of the same holding merged).
Issuers added (1)
JAPAN (GOVERNMENT OF) 5YR #1870.39%
Issuers removed (0)
None.
Rows compared: 1 → 2 issuers. The issuer file lists 303 positions but does not identify individual issues (no code per row): rows with the same name — e.g. the issues of one sovereign — are merged into one, so additions, removals and weight changes here are per issuer. Files of 20 Aug and 31 Aug.

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.
