Monitoring insider trading activity provides valuable insights into how company executives and major shareholders view their stock’s prospects. While insider purchases can signal confidence in a company’s future performance, sales don’t necessarily indicate pessimism, as executives may sell shares for various personal financial reasons, including portfolio diversification or tax planning. Nevertheless, tracking these transactions alongside other fundamental and technical indicators can help investors make more informed decisions about their portfolios.
