Review Questions

• How does overconfidence affect an investor's decision-making process?
  • Overconfidence affects an investor's decision-making by causing them to believe they possess superior knowledge or skill. This belief often leads them to underestimate risks and overestimate potential returns, resulting in overly aggressive investment strategies. As a result, these investors may engage in excessive trading and take on risks that could jeopardize their financial well-being.
• In what ways can overconfidence contribute to market inefficiencies?
  • Overconfidence can contribute to market inefficiencies by leading investors to make irrational decisions based on inflated self-perceptions. When too many investors share this bias, it creates volatility as they react similarly to market news and trends, ignoring fundamental valuations. This collective behavior can distort asset prices and contribute to phenomena like bubbles and crashes.
• Evaluate the role of overconfidence in corporate finance decisions and its potential long-term consequences.
  • Overconfidence plays a significant role in corporate finance decisions by influencing executives' risk assessments and investment strategies. When leaders overestimate their capabilities or the accuracy of their forecasts, they may engage in overly ambitious projects or acquisitions without adequately considering risks. The long-term consequences can include diminished shareholder value, increased debt levels, and ultimately, financial distress for the company if these decisions do not yield expected results.
