Why Investors Track Insider Transactions

Monitoring insider activity can help investors better understand how corporate leaders and significant shareholders are positioning themselves. When executives, board members, or major owners buy or sell stock, those moves may reflect their perspective on a company’s outlook.

Insider buying can suggest conviction about future performance, while insider selling may raise questions. However, sales can occur for many reasons, including diversification, tax planning, or personal liquidity needs. For that reason, insider transactions are often most useful when evaluated alongside other factors such as financial results, sector dynamics, and broader market conditions, rather than as a standalone signal.
