SEC Form 4 Filings
Understanding how corporate insiders report their stock transactions to the SEC.
What is SEC Form 4?
SEC Form 4 is a document that must be filed with the Securities and Exchange Commission (SEC) whenever there is a change in the holdings of company insiders. This includes:
- Purchases of company stock by insiders
- Sales of company stock by insiders
- Exercise of stock options
- Gifts of company securities
- Other transactions that change beneficial ownership
Form 4 provides transparency into insider trading activity and helps investors understand how executives and directors view their company's prospects.
Filing Requirements
2-Day Rule
Insiders must file Form 4 within 2 business days of the transaction date. This ensures timely disclosure of insider trading activity.
Who Must File?
Officers, directors, and beneficial owners of more than 10% of a company's equity securities must file Form 4.
Public Availability
All Form 4 filings are publicly available through the SEC's EDGAR database, providing transparency for all investors.
