Why Monitor Insider Trading?
Tracking insider transactions can provide valuable insights for investors as these trades are executed by individuals with intimate knowledge of their companies. While insider buying often signals confidence in a company’s future prospects, insider selling may occur for various reasons unrelated to company outlook, such as personal financial planning. Investors should consider insider activity as just one of many factors in their investment decision-making process, always conducting thorough research before making investment decisions.
