Why Monitor Insider Activity
Tracking insider transactions provides valuable insights into how a company’s executives, directors, and major shareholders view the stock’s prospects. When insiders buy shares with their own money, it often signals confidence in the company’s future performance. Conversely, insider selling might indicate concerns about valuation or future challenges, though it can also reflect personal financial planning needs. While insider activity alone shouldn’t drive investment decisions, it represents one important piece of the puzzle when evaluating potential investments.
