Why Monitor Insider Activity
Tracking insider transactions can provide valuable insights for investors. When corporate executives, board members, or major shareholders buy or sell company stock, they often possess deeper knowledge about the company’s prospects. Insider buying may signal confidence in future growth, while selling could indicate potential concerns—though it’s important to note that insiders sell for various reasons including portfolio diversification, tax planning, or personal financial needs. Rather than viewing insider activity as a standalone signal, investors should consider it as one piece of a broader investment analysis alongside financial performance, industry trends, and overall market conditions.
