Why we built OpenStocks

The problem with closed dashboards

Most "smart money" tracking sites are scraping the same public filings — 13F, Form 4, STOCK Act PTRs — and reselling them as a polished UI behind a paywall. The data is already public. What's not public is a clean, queryable copy.

OpenStocks closes that gap. Every page on this site links straight back to the original SEC accession or House clerk PDF. Nothing is opaque, and nothing is reformatted in a way you can't reproduce.

What you can do here

  • Track 70+ super-investors quarter-over-quarter (13F).
  • Read every Form 4 insider transaction the SEC publishes, ranked by net dollar flow.
  • Browse U.S. House and Senate STOCK Act PTRs with the underlying PDF one click away.
  • See composite signals when institutions, insiders, and Congress are all agreeing on the same ticker.

Why open?

Three reasons:

1. Reproducibility. A research result that depends on a closed dataset isn't a research result; it's a vendor pitch. We want OpenStocks queries to be reproducible from the same SEC URLs we link to. 2. Cost discipline. Premium dashboards charge $1,000+/year for what is effectively a SQL query against public data. We can do better. 3. Trust. When you can read the raw filing yourself, you don't have to take our word for any number.

What's next

We're aligning OpenStocks with the StockCircle product feature set — committee relevance, AI-summarized earnings calls, monthly investor recaps, and embeddable charts. The full backlog lives in the README. If something's missing, open an issue.
