When company insiders buy or sell company stock, they must file a Form 4 with the U.S. Securities and Exchange Commission (SEC) disclosing the transaction. 13F forms are used for large money managers who hold more than $100 million in assets, while 13D or 13G forms are used for people or institutions that own more than 5% of a company’s stock. Each of these forms provides a way for investors to track significant positions made by major investors.
