SEC Form 4 screener: filters that matter

A Form 4 screener is most useful when it reduces noise. SEC filings can include open-market transactions, equity awards, option exercises and tax withholding. A screener should help users sort those events without hiding the original filing.

Useful Form 4 screener filters

Transaction type

Separate open-market buys and sales from grants, awards and tax-related transactions.

Insider role

Highlight CEOs, CFOs, directors and 10% owners separately from routine officer filings.

Value

Use thresholds so small administrative filings do not overwhelm the workflow.

Cluster activity

Flag situations where multiple insiders file around the same company in a short window.

Source

Keep the original SEC filing one click away for verification.

Why plain-English context helps

Transaction codes such as P, S, M, A and F can be confusing for newer users. A plain-English summary helps the user understand what the filing appears to report before opening the official SEC document.
