SEC Form 4 is a filing that must be submitted when there is a change in the holdings of company insiders — including directors, officers, and shareholders owning more than 10% of a company's stock.
The data is updated in real-time as new Form 4 filings are submitted to the SEC EDGAR system.
A 4/A filing is an amended Form 4. It indicates that the original filing has been corrected or updated by the insider.
We display purchases (P), sales (S), and option exercises (M) — the most common and meaningful insider transaction types.
