Every screener tells you who owns a healthcare name. This one tells you what kind of money it is.
An index fund, a multi-strategy pod running a three-week catalyst trade, a PIPE financier who bought at a discount, and a physician-founded specialist who spent four months on the mechanism all render as identical rows on a normal ownership table. They mean completely different things.
The money is classified first, and everything else — sorting, scoring, filtering, comparison — runs on that classification. Schedule 13D/G filings are carried alongside, because they land within days of a 5% crossing rather than 45 days after a quarter ends.

The register, by kind of capital
Every institution in the dataset carries one of eight classes and an explicit scoring weight — index money is weighted at zero, specialist conviction at full. Counts below are institutions, not dollars.
It classifies the money
163 institutions in eight classes of capital, each with a scoring weight: an index fund counts for nothing, a pod for a quarter of a specialist. A 13F files one line per instrument, and each is labelled as filed — ownership counts the long claim, so a put is never read as belief, and nothing is called a hedge or a short, because the filing does not say which it is.
It shows what moved, and what is due
149 books set against their own 2026-03-31 filings — opened, added, trimmed and exited, including the exits most trackers throw away. 373 Schedule 13D/G filings since the quarter closed, because a 5% crossing is filed within days. A catalyst calendar whose every row cites the filing its date came from, and a company that has stopped trading is shown as stopped, from its own filing index.
Every figure goes back to a filing
148 of 149 books carry every line their information table filed. 700 of 701 research profiles cite an SEC filing and none rests on a newswire or an aggregator. Every security carries the CIK EDGAR knows it by, and a percentage that would be wrong — a reverse split putting holdings and quote on different share bases — is withheld with a warning rather than shown.
Not here yet
This is in early beta, so it is worth being plain about what is missing rather than letting you find out. Everything below is designed and specified; none of it is half-built behind a flag. Next means the work is unblocked and scheduled; planned means it is waiting on a decision or on data the dataset does not yet hold.
Ownership over timenext
Five years and 2,536 filed books are already loaded and validated. Every past event on a security already shows the 13F either side of it. Still to come: how one manager’s position moved quarter by quarter, how the cohort rotated between therapeutic areas, and how long a position has actually been held.
Lonely conviction, over timenext
Today a lonely position is a single-quarter photograph. It cannot tell you whether a manager has been alone in it for eight quarters and adding, or is alone because two other books sold out from under them. Those are opposite situations.
Build a rule and replay itplanned
Compose a hypothesis out of the classification layer — “the top ten oncology specialists’ five most-overlapped holdings” — and replay it quarterly across the corpus. It would state what a rule would have owned, never that you should own it.
Long and short exposureplanned
The instrument is labelled today; the aggregate is not. This would show how much of a name the tracked cohort is long through common and warrants against how much it is short through puts — as a description of the positions, not a claim about anyone’s view.
