- Investors do not always act rationally, a result of behavioral biases.
- Mental biases can lead to bad decisions and mistakes.
- Behavioral biases are either cognitive errors or emotional biases. A given bias may have aspects of both.
- Cognitive errors stem from statistical, information-processing, or memory errors.
- Emotional biases stem from impulse or intuition. Investor feelings matter.
- Cognitive errors are easier to correct.
- Emotional biases are harder to correct because feelings are difficult to change.
- To adapt to a bias is to recognize, accept, and adjust for the bias.
- To moderate a bias is to recognize the bias and attempt to reduce or even eliminate it.
- Cognitive errors come in two categories: belief perseverance biases and information-processing biases.
- Belief perseverance errors reflect an emotional need to maintain beliefs. Belief perseverance is related to the psychological concept of cognitive dissonance.
- Examples of belief perseverance biases include conservatism, confirmation, representativeness, the illusion of control, and hindsight.
- Information-processing biases stem from illogical, irrational processing of information.
- Information-processing biases include anchoring, mental accounting, framing, and availability.
- Emotional biases include loss aversion, overconfidence, self-control, status quo, endowment, and regret.
- Understanding and detecting biases are the first steps in overcoming their effect on financial decisions.
- Behavioral finance may explain deviations from efficient markets and market anomalies.
