SEC Filing Requirements for Insider Trades
Trading of all stock is regulated by the Securities and Exchange Commission (SEC). Officers and directors of companies, owners of restricted stock, and owners of more than 10% of a company's stock are legally required to let the SEC, and thereby the public, know when they sell, or intend to sell their stock. Today's Brief outlines the forms that are used for this purpose.
Form 4 filings state the changes to an insider's holdings when they occur. The Form 4 includes purchases and sales as well as exercise of options, disposition by gift, or other transactions.
