Slice of Stock

Ownership, both directions

Who owns the biggest slice, and what stock do they own?

499 companies. The 140 largest are researched with AI against primary filings and carry both directions: the stakes they hold in others, and the holders on their own register, 2042 positions in all with a source and a date on every one. The other 359 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 registers359 more companies, 368,281 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.

Unique findings

12 ownership facts that a screen or a 13F sweep does not show, each one traced to the filing that proves it. They are grouped by the kind of trap rather than by industry, because the same trap turns up at unrelated companies and the recurrence is the useful part.

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, and who owns them

221 private companies that the researched set holds stakes in. No 13F reports any of them, which is why the 359 registers cannot see them and why these pages exist at all. Each one lists its disclosed holders with the filing behind every figure.

Every private company covered, most widely held first:

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.
