Review Questions

• How does self-attribution bias impact an investor's decision-making process?
  • Self-attribution bias impacts an investor's decision-making by leading them to attribute their successful investments to their own skills while viewing unsuccessful ones as a result of external circumstances. This skewed perception can cause investors to become overconfident, relying heavily on their past successes and neglecting critical analysis of market conditions. Consequently, this may result in poor future investment choices, as they may not learn from their mistakes.
• Discuss how self-attribution bias relates to other cognitive biases such as overconfidence and confirmation bias in the context of investing.
  • Self-attribution bias is closely related to overconfidence and confirmation bias in investing. Overconfidence can amplify the effects of self-attribution bias, as individuals may believe they are more skilled than they truly are, which reinforces their success stories. Meanwhile, confirmation bias leads investors to focus on information that validates their prior decisions and ignores contrary evidence, creating a feedback loop that strengthens self-attribution tendencies. Together, these biases can distort an investor's judgment and lead to increasingly risky financial behaviors.
• Evaluate the implications of self-attribution bias for financial market efficiency and investor behavior.
  • Self-attribution bias has significant implications for financial market efficiency and investor behavior. When many investors exhibit this bias, it can lead to mispricing of assets as individuals overly celebrate their successes and fail to adjust for losses appropriately. This behavior not only affects individual portfolios but also contributes to broader market inefficiencies, such as bubbles or crashes. By understanding self-attribution bias, investors can improve their decision-making processes, promoting a more stable and efficient market environment.
