Every quarter, institutions disclose their holdings to the SEC. The filings are public — and scattered across thousands of documents built for regulators. Here is what we do with them.
Any firm managing more than $100 million must disclose its US holdings to the SEC within 45 days of each quarter end. Hedge funds, pension funds, banks, insurers. Thousands of filings, one per firm, each a separate document.
We read the filings from the SEC and organise them by stock, by investor, and by investor type. Every holding keeps its link back to the original filing.
A filing lists a security and a share count. It does not tell you what sector the company is in, where it is listed, or where the price sat that quarter. We add that, and label it as separate from the SEC data.
A PDF, published once a quarter, covering one stock, one investor, or one investor type.
From SEC filings. Every figure traces back to an original filing you can open yourself.
From market data providers. Useful context around the filing, but not part of what the institution disclosed.
We keep these separate because mixing them would let us present something as SEC-disclosed when it is not. Every report labels which is which.
A 13F covers long US equity positions. It does not include:
Only firms above $100 million must file, and some positions can be withheld under a confidentiality request. So a 13F is a substantial view of what large investors own — not a complete one.
It is also not live. The 45-day deadline is set by the SEC, so every report describes a quarter that has already closed.
Holdings, prices, and moving averages in a report are all as of the same quarter-end close.
We do this on purpose. A current price sitting beside three-month-old holdings would invite you to multiply one by the other and reach a number that means nothing.
The FAQ goes into more detail, and the glossary defines the terms.
HoldingsLens compiles data from public institutional investment filings (SEC Form 13F). It does not constitute financial advice, investment recommendations, or a solicitation to buy or sell any security. Past holdings do not predict future performance. All investment decisions remain the sole responsibility of the user.
