Why Monitor Insider Activity

Tracking insider transactions provides valuable insights into how a company’s executives and directors view their own stock’s prospects. Significant insider buying often signals confidence in the company’s future performance, while substantial selling might raise questions about future growth or valuation concerns. However, investors should remember that insiders sell for many reasons unrelated to company outlook, including diversification, tax planning, or personal financial needs. The most reliable signals come from patterns of insider behavior rather than isolated transactions.
