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.
