When discussing legal matters, the term "insider" refers to any officer, director, or beneficial owner holding more than ten percent of a company's equity securities, as stipulated in Section 12 of the Securities Exchange Act of 1934. This includes executives in the c-suite and significant hedge funds. Such insiders are required to report their transactions through a Form 4 filing, which must be completed within two business days of the transaction. A new purchase by a company insider is a indication that they anticipate the stock will rise. On the other hand, insider sells may not necessarily indicate a bearish view and can be motivated by various factors. ### A Deep Dive into Insider Transaction Codes Delving into transactions, investors typically prioritize those unfolding in the open market, as precisely outlined in Table I of the Form 4 filing.
