The trading activity by insiders of any company can be of interest to both investors and the public. This activity has the potential to be valuable information when deciding whether to invest in a company's stock or not.
Because the insiders of a company have access to non-public information about the company's operations, financial performance, or future plans, they have insights or access not readily available to the general public or regular shareholders.
Naturally, this advantage comes with strict legal obligations and restrictions to prevent the misuse of inside information. Although many insider trades are routine, history has shown that insider buying and selling of company stock has signaled that a significant event is about to happen that may cause a company’s stock to move significantly in the near future.
The Securities and Exchange Commission has filing requirements to ensure investors and the public can access and review insider trading activities. This allows them to make more informed decisions based on potential conflicts of interest or signals about the company's prospects. It also helps the SEC monitor insider trading activity and enforce securities laws.
But if you wish to monitor this activity yourself, there are free and paid tools available for the expressed purpose of tracking the trading activity of company insiders.
