HoldingsLens turns institutional investment disclosuresSEC Form 13F — A mandatory quarterly disclosure filed by institutions ($100M+) with the U.S. Securities and Exchange Commission. It reveals every stock position they hold. into clear, visual, downloadable intelligence.
* Based on full SEC 13F universe across all institutional portfolio filings tracked.
Every quarter, institutions disclose billions in positions through quarterly investment disclosures. But the raw data is fragmented, technical, not built for investors.
13F forms are dense legal documents with no structure, no visuals, and no way to compare across institutions or time periods.
There is no single place to see the full picture across institutions, sectors, and time.
It would take you hours of research and dozens of tabs just to see the overview — we've already done it.
We do the heavy lifting — parsing, structuring, and visualising quarterly investment disclosures so you can focus on the insight, not the extraction.
