Review Questions

• How do cognitive biases manifest in investor behavior and impact trading decisions?
  • Cognitive biases like confirmation bias and anchoring significantly impact how investors process information. For instance, confirmation bias may lead an investor to only seek information that supports their existing beliefs about a stock, disregarding contrary data. This can result in poor investment choices as they may hold onto losing positions longer than they should, ultimately affecting their overall trading performance.
• Discuss the implications of loss aversion on investor decision-making and market dynamics.
  • Loss aversion causes investors to fear losses more than they value gains, leading them to make overly cautious decisions. For example, an investor might hold onto a losing stock for too long instead of cutting losses due to the emotional pain associated with realizing a loss. This behavior can create a reluctance to sell underperforming assets, resulting in distorted market prices and prolonged downturns.
• Evaluate the role of herd behavior in shaping market trends and its connection to investor psychology.
  • Herd behavior illustrates how collective emotions can influence individual decision-making in financial markets. When investors follow the crowd—whether in buying or selling—they often create significant price movements that do not align with underlying fundamentals. This behavior can lead to the formation of market bubbles or crashes, as seen in historical events like the Dot-Com Bubble or the 2008 Financial Crisis. Recognizing the psychological triggers behind herd behavior is essential for understanding market dynamics.
