Find companies where insiders are buying on the open market at the same time the company is filing material 8-K events. The pipeline pulls both signals straight from SEC EDGAR, joins them per company, and scores each one 0 to 100 with a conviction tier you can act on.

The core signal is 100% SEC EDGAR: public, free, structured filings with no antibot risk. Optional LinkedIn hiring enrichment is off by default.

What it does

1. Form 4 insider transactions. Pulls every reported insider transaction for your tickers over the lookback window and isolates open-market purchases (transaction code P), which are the real conviction buys, from sales (code S).
2. 8-K material events. Pulls material corporate filings for the same companies and categorizes the item codes into catalysts (M&A, earnings, executive changes, financing, cybersecurity) and bearish risk flags (bankruptcy, delisting, impairment, non-reliance restatement, auditor change, layoffs).
3. Optional hiring momentum. When enabled with a ticker-to-LinkedIn-URL map, adds open-role count and hiring trend as a growth confirmation.
4. Join and score. Joins all sources on issuer CIK and scores each company:
   • Insider buy intensity (cluster buys by multiple insiders, total dollar value, buy/sell balance)
   • Material catalyst presence and type
   • Optional hiring momentum

Tiers

• high-conviction — score 70+, a cluster buy (2+ distinct insiders buying), and a material catalyst, with no bearish risk flag.
• accumulation — at least one insider open-market buy and a score of 40+.
• watch — appeared in the window but did not clear the accumulation bar, or carries a bearish risk flag.

distressed: true marks any company with a bearish 8-K (bankruptcy, delisting, non-reliance restatement, etc.); these are capped at the watch tier no matter how strong the buying.

Input

Pricing and combined cost

You are charged per scored company: watch $0.04 / accumulation $0.10 / high-conviction $0.18. The first 3 high-conviction rows per run are free so you can validate output.

This pipeline calls two child actors on your behalf — sec-form4-insider-tracker and sec-8k-event-tracker (and linkedin-company-hiring-tracker only when enrichment is on). Those actors charge their own per-event fees, which appear on your bill in addition to this pipeline's per-company charge. Keep maxItemsTotal sized to your ticker list to control the combined cost.

Who it is for

Retail investors, finance newsletter writers, and quant hobbyists who want insider accumulation cross-referenced with material catalysts in one scored feed, without scraping or parsing EDGAR XML themselves.
