Why Monitor Insider Activity?
Tracking insider buying and selling can provide valuable insights for investors. When company executives, directors, or major shareholders put their own money into their company’s stock, it may signal confidence in future prospects. Conversely, insider selling might reflect personal financial planning or concerns about valuation. While no single transaction should drive investment decisions, patterns of insider activity can complement fundamental analysis and help investors understand how those closest to the company view its current valuation and future potential.
