OpenInsider aggregates Form 4 disclosures with filters for dates, trade types, values, and insider roles to research reported transactions.

About

OpenInsider tables show filing and trade dates, insider names and roles, transaction types, quantities, and values. Views include cluster purchases and executive transactions. Filters cover ticker, dates, trade type, value, industry, and position.

A filing date can differ from the actual transaction date. The site also marks amendments, derivatives, and multiple transactions. Check SEC filings for context and distinguish open-market trades from gifts, option exercises, and tax payments.
