An end-to-end pipeline that pulls SEC Form 4 filings from EDGAR, keeps only open-market insider purchases, and lets you explore them by company, executive and sector.

    The problem

    Insider purchases are public but buried in filings. Can you surface the interesting ones, such as several executives buying at once, and see what happened next?

  2. 02Chapter

    What I did

    • Ingests SEC Form 4 filings from EDGAR and isolates open-market purchases.
    • Stores transactions with price history in PostgreSQL for thematic analysis, with examples like quantum, space and mega-cap tech.
    • Designed cluster-buy scoring and forward-return backtests against SPY, plus a dashboard to explore signals.

    Afterwards

    A research experiment. No claim of profitable signals or investment performance.
