Investors should stay tuned to insider buying and selling activities as they can provide valuable insights into a company’s prospects. While insider transactions alone should not be the sole basis for investment decisions, they can offer important context when combined with other financial metrics and market analysis. However, it’s crucial to remember that insiders may have various reasons for their transactions, and not all insider activity is indicative of a company’s future performance.
