Insider trades
Open-market buys and sells by officers, directors and 10% owners, from SEC Form 4. Usually filed within two business days.
About this data
- What it is
- When a company's officers, directors or owners of more than 10% buy or sell its stock, they must report the trade to the SEC on Form 4. This feed shows purchases and sales on the open market; stock grants, option exercises and shares withheld for tax are left out.
- Who files it
- The insider, usually through the company, within two business days of the trade.
- How current
- We collect new filings throughout the day on SEC business days.
- Worth knowing
- Sales are often routine: insiders sell to diversify, to pay taxes, or under a 10b5-1 plan set up months in advance. A purchase with their own money is less common, which is why many investors pay closer attention to it.
All of this comes from public filings.
