Form 4
A document that must be filed with the Securities and Exchange Commission (SEC) whenever there is a material change in the holdings of company insiders (including shareholders owning 10% or more of the company's outstanding stock).
Investopedia Commentary
SEC regulations require insiders to report any material changes in their holdings of their affiliated company, via the submission of a Form 4, before the tenth day of the month following the material transactions. This covers buy and sell orders on the open market as well as the exercise of company stock options.
