Review Questions
How does behavioral finance critique challenge traditional assumptions about investor behavior in the stock market?
Behavioral finance critique challenges traditional assumptions by suggesting that investors do not always act rationally, as previously thought. Instead of making decisions based solely on available information, investors are influenced by psychological factors like emotions and cognitive biases. This leads to irrational behaviors such as panic selling during market downturns or exuberance during booms, resulting in inefficiencies in the stock market that standard financial theories cannot explain.
Analyze the impact of cognitive biases on investment decisions in the stock market according to behavioral finance critique.
Cognitive biases significantly impact investment decisions by distorting how investors perceive risks and returns. For instance, overconfidence can lead investors to underestimate risks and overestimate their ability to predict market movements. Similarly, loss aversion may cause investors to hold losing stocks for too long in hopes of a rebound instead of cutting their losses. These biases contribute to phenomena such as market bubbles and crashes, illustrating the need for a deeper understanding of investor psychology beyond traditional models.
