Equity GraphS&P 500 registers, and the 20 largest traced to filings

Ownership, both directions

Who owns the biggest companies, and what they own back

499 companies. The 20 largest are researched by hand against primary filings and carry both directions: the stakes they hold in others, and the holders on their own register, 369 positions in all with a source and a date on every one. The other 479 are S&P 500 constituents with a register built from institutional 13F filings. Search reaches the 586 largest managers too, so a name like Vanguard lands on what it owns rather than on who owns it.

S&P 500 registers479 more companies, 680,200 manager positions, from 13F filings

Register only: who owns them. What they own has not been researched, and these pages say so rather than showing an empty holdings section. Sorted by how many managers reported a position. Search above reaches all 499.

They own each other

Edges inside the researched set. Where both sides were researched independently, the two share counts agree exactly, which is the strongest evidence available that a figure is real rather than plausible.

Private companies more than one of them holds

No 13F reports these, which is why the 488 registers cannot see them and why the researched pages exist at all.

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.

2 constituents have no register: FedEx Freight, Honeywell Aerospace. 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.
