Behavioral Finance Flashcards
Behavioral Finance
Relates behavioral and cognitive psychology to financial planning and economics in an attempt to understand why people make certain choices during the financial decision making process. Client actions are organized into two groups - cognitive errors and emotional biases.
Cognitive Errors
Primarily due to faulty reasoning and arising from lack of understanding of proper statistical analysis techniques, information processing mistakes, or memory errors. These errors can be connected or mitigated with better training or information.
Illusion of Control Bias
Exists when market participants think they can influence outcomes when they cannot. It is often associated with emotional biases: Illusion of Knowledge, self-attribution, and overconfidence biases.
Hindsight Bias
Selective memory of past events, actions, or what was knowable in the past. Clients tend to remember their correct views and forget the errors. They also overestimate what could have been known.
Confirmation Bias
Occurs when market participants look for new information to support an existing view. Clients who get involved with the portfolio process by researching holdings may become overly attached to some investments and only bring up information favorable to the holding.
Representativeness
Based on belief the past will persist and, as a result, new information is classified based on previous experiences. While this may be efficient, the new information can be misunderstood if it is classified base on superficial resemblance to the past or a classification.
Base Rate Neglect (Representativeness)
Where the base rate (probability) of the initial classification is not adequately considered.
Sample Size Neglect (Representativeness)
Makes the initial classification based on an overly small and potentially unrealistic sample of data.
Mental Accounting
“Money jar mentality”. Involves the tendency of individuals to put their money into separate accounts based on the function of these accounts.
Self-Attribution Bias (Ego)
An ego defense mechanism that occurs to avoid the cognitive dissonance associated with having to admit making a mistake.
Self-Attribution Bias
An ego defense mechanism that occurs to avoid the cognitive dissonance associated with having to admit making a mistake.
Anchoring
Irrational decisions based on information that should have no influence on the decisions at hand. Especially risky when people know little about the product being purchased, the service being delivered, or the investment being made.
Adjustment
Involves clients clinging to on clinging on to an initial estimate and not adjusting for new information.
Outcome Bias
The tendency for individuals to take a course of action based on the outcomes of prior events.
Framing Bias
Asserts that people are giving a frame of reference, a set of beliefs or values, which they use to interpret facts or conditions as they make decisions.
