first snapshot on record
The Holdings column counts the snapshot’s positions as declared by the issuer, cash and duplicate lines included; the comparison in “What changed” excludes cash and merges lines of the same holding — the two totals may differ. The latest month’s AUM is the most recent value of the ongoing month.
Month-on-month comparisons (holdings added, removed, weight changes) start with the 2 September 2026 snapshot. The basket snapshot archive starts in August 2026.
