Review Questions

• How does recency bias affect investor decision-making in volatile markets?
  • Recency bias can significantly impact investor decision-making in volatile markets by causing them to react strongly to the most recent events, such as sharp price movements or sudden news releases. This often results in impulsive buying or selling, as investors may ignore historical trends and fundamentals. Consequently, they may miss opportunities for long-term gains and increase their exposure to risk.
• Discuss how awareness of recency bias can improve investment strategies.
  • Awareness of recency bias can lead investors to adopt more disciplined investment strategies that prioritize long-term objectives over short-term fluctuations. By recognizing this cognitive trap, investors can implement systematic approaches, such as dollar-cost averaging or setting predefined buy/sell rules based on analysis rather than emotion. This helps create a more rational investment process and reduces the likelihood of making poor decisions based on fleeting market trends.
• Evaluate the implications of recency bias on market efficiency and investor behavior.
  • Recency bias poses significant implications for market efficiency as it can lead to mispricing of assets when many investors are influenced by short-term performance. This behavior contributes to market volatility and can create bubbles or crashes when collective sentiment swings dramatically based on recent events. As investors increasingly react to the latest news rather than long-term fundamentals, it undermines the efficient market hypothesis, which assumes that all available information is reflected in asset prices.
