Why Monitor Insider Transactions
Tracking insider buying and selling can provide valuable insights for investors. When company executives, directors, or major shareholders purchase or sell stock, they often possess a deeper understanding of the company’s prospects. Significant insider buying may signal confidence in future growth, while substantial selling could indicate concerns about valuation or upcoming challenges. However, insiders sell for many reasons unrelated to company outlook, including diversification, tax planning, or personal financial needs. Rather than viewing these transactions in isolation, investors should consider them as one piece of a broader investment analysis, alongside financial performance, industry trends, and overall market conditions.
