Why Monitor Insider Transactions?
Tracking insider buying and selling can provide valuable insights for investors. Insiders, such as executives and major shareholders, often have unique knowledge about their companies’ prospects. While insider buying may signal confidence in the company’s future, selling can occur for various reasons including portfolio diversification, tax planning, or personal financial needs. Rather than using insider activity as a standalone signal, investors should consider it as one component of comprehensive due diligence alongside fundamental analysis, industry trends, and broader market conditions.
