Free insider trading dataset from SEC ownership filings

Research reported insider transactions from SEC Forms 3, 4 and 5. Download the shared SEC ownership dataset as Parquet on Hugging Face or use the open-source GitHub tools to query insider transactions in SQLite.

Dataset coverage

Reporting owners, issuers, transaction codes, filing dates and ownership disclosures. Select insider_transactions or insider_filings.

Use the public filing clock

Purchases, sales, grants and option exercises are separate events. Use public filing availability rather than an earlier transaction date.

Source data and simulated strategies

The downloads contain disclosure data. Strategy returns on this page come from separate modeled backtests.
