Method, and what it misses

Where the register data comes from

Curated from primary filings. Every figure carries its source, the date it was measured, and whether it was filed or modelled. Positions nobody has published are left unsized rather than estimated into existence.

Where the register data comes from, and what it misses

Built from the SEC's quarterly Form 13F data set for filings made March to May 2026, using the quarter ended 31-mar-2026 only, so no register mixes quarters. A 13F reports US listed, long, US custodied positions, which makes any register from it a floor rather than a level.

5 constituents have no register: AZUL SA, FedEx Freight, Honeywell Aerospace, Parabilis Medicines, Inc., X-Energy. No manager reported them at all this quarter. Both are newly separated registrants with their own new filing identities, and filers still report only the parent company, so there is nothing yet to aggregate. They are deliberately not given their parent's register, which would credit them with holdings nobody reported. A register will appear once managers report the new tickers.
