Investment psychology refers to the emotional and cognitive factors that influence investors' decisions in the financial markets. It encompasses how feelings like fear and greed can lead to irrational behaviors, such as panic selling during market downturns or excessive buying during market booms. Understanding these psychological triggers can help investors make more informed choices. Additionally, investment psychology examines biases that affect decision-making, such as overconfidence and loss aversion. These biases can lead to suboptimal investment strategies and missed opportunities. By recognizing and managing these psychological influences, investors can improve their chances of achieving long-term financial success.
