Who owns my stocks?
Every tracker on the internet makes you start from the investor: pick Buffett, read his book, hope one of your names is in it. This runs the other way. Paste what you own and find out which institutions, which members of Congress and which company insiders are on record holding the same things.
Most tools make you start from the investor and read down their book. This starts from your list and works backwards, which is the direction the question actually runs.
Three registers, one answer
Ownership evidence comes from three separate legal disclosure regimes, each with its own deadline, its own coverage and its own blind spot. This report reads all three and says which one each fact came from, because they are not equally strong.
Form 13F
Anyone running over $100m in US-listed equities files within 45 days of quarter end. It is the strongest of the three: a real, audited position. It is also long-only, US-only and up to 45 days stale.
The STOCK Act
Members disclose trades within 45 days, in value bands rather than figures. The weakest of the three as a signal: many hold managed accounts they never direct, so we weight it lowest.
Form 4
Officers and directors file within two business days. Fast and specific, but we count only open-market purchases — grants, option exercises and tax withholding are compensation, not decisions.
Where this leads next
If you want the reverse view — one investor's whole book rather than your list — the super investor reports email you any filer's latest quarter. If you want to be told when several of them buy the same company, that is the consensus alert. And if what you actually want is a verdict on the portfolio rather than a map of who else owns it, the portfolio checkup grades it.
Straight answers
Does a fund owning my stock mean it is a good stock?
No. It means a professional investor thought so at some point in the last three to six months, for reasons they did not publish, with a time horizon and a tax position that are not yours. Professional investors are wrong regularly and expensively. Treat overlap as corroboration worth reading into, never as a verdict.
One of my holdings shows zero funds. Is that bad?
Usually it is a fact about the filing rules rather than the company. Form 13F only captures US-listed long positions held by managers running over $100 million, so small caps, recent listings and every non-US listing are systematically under-represented. A London or Johannesburg listing will almost always show zero here even if it is widely institutionally held at home.
What is the conviction score?
Our own composite out of 100, from four independent sources: institutional holders count most, open-market insider buying next, congressional disclosures least, and our own rating is capped at a quarter of the total so the number stays a measure of what other people did rather than a restatement of our opinion. Each score shows its own breakdown.
How current is any of this?
13F holdings describe the last completed quarter and arrive up to 45 days after it ends. Congressional disclosures arrive up to 45 days after the trade. Form 4 insider filings arrive within two business days and are the only near-live part. Every section states which it is.
Do you store my tickers?
Only if you ask for the email or the weekly watch. The on-screen report runs and returns without writing anything down. If you subscribe to the watch we store the ticker list so we know what to check, and unsubscribing is one click from any email.
Why do you weight politicians so lightly?
Because a congressional disclosure frequently describes a managed account the member does not direct, and sometimes a spouse's account. Treating that as equal evidence to a fund manager taking a deliberate position would be the most misleading thing this report could do. It is included because it is interesting and because people want it, weighted low because that is what it is worth.
