Run on Apify - $0.20 / result Use via MCP (free)

Track insider trading from SEC Form 4 filings and find clusters of open-market buying, scored and ranked. When several company insiders (CEO, CFO, directors) buy their own stock within a short window, it is one of the most widely studied patterns in quantitative-finance research. This tool scans SEC EDGAR Form 4 filings, groups open-market purchases (transaction code P) by company, and returns ranked, scored insider-buy clusters as clean JSON. Not a raw data dump: the screened, structured signal.

What it does

  • Filters to open-market purchases only (code P), the buys most relevant for screening.
  • Detects clusters: two or more distinct insiders buying the same stock within your lookback window.
  • Scores each cluster 0-100 (STRONG / MODERATE / WEAK) by number of insiders, total USD value and seniority.
  • Returns clean JSON with a direct SEC EDGAR link for every cluster, so you can verify the raw filings.

Who uses insider-buying data

  • Retail quants and algorithmic traders building screening factors.
  • Fintech and trading apps embedding insider data.
  • Research desks and financial newsletters surfacing notable insider activity.

A self-serve, pay-per-result alternative to premium platforms like InsiderScore and Fintel ($99-$499 per month).

How it works

The tool reads real-time SEC EDGAR Form 4 filings, the official public U.S. registry. No anti-bot workarounds, no personal data, rate-limited and compliant. Each run reads the latest filings.

Example

A real cluster detected in live SEC data: four insiders including the CFO bought $1.17M of the same stock on the same day, score 71.7 (MODERATE).

FAQ

Does it include sells?

No. It covers cluster buying (code P). Sells, grants and option exercises are excluded.

Why are some runs empty?

Open-market insider buy clusters are genuinely rare, which is exactly why they are worth tracking. Run daily and let clusters accumulate.

Is this investment advice?

No. It is data for research, screening and monitoring. Historical patterns do not guarantee future results.
