Compared to Q1 2026. SEC Form 13F filings are due within 45 days of quarter-end plus a short buffer for late filers — quarters still inside that window are skipped in favor of the most recent fully-reported pair. Change vs prior quarter not shown: filer coverage differs too much between these two quarters for a reliable comparison.
