Behavioral Finance Flashcards
Heuristic
Any approach to problem-solving that employs a more practical method that is not guaranteed to be optimal or rational, but is sufficient for reaching a short-term goal or approximation (e.g. rules of thumb, educated guess)
Anchoring
Investor sets value at the initial point of information (e.g. buy price)
Prospect Theory
Suffer more from losses than benefit from gains
Recency bias
Makes investor focus more on the most current events, leading to faulty predictions that this is always how it will be
Overconfidence
Leads investors to overestimate their knowledge, underestimate risks and exaggerate ability to control events and predict outcomes.
Factors leading to overconfidence: choice, task familiarity, information, active involvement, past success
Disposition Effect
People seek pride and avoid regret.
Sell winners to quickly and hold losers too long
House Money Effect
Take more risk
Snakebite Effect
Take less risk
Break-evenitis
Take more risk
Mental Accounting
Leads to naive diversification (e.g. the assumption that simply investing in enough unrelated assets will reduce risk sufficiently to make a profit)
Home Bias
Familiarity with something leads to stock concentration (e.g. Blair and Shell holding %)
Herd Mentality
Natural bias to follow the crowd and invest how others are
Optimism
Leads to exuberance, which can lead to market bubbles
Attachment Bias
Holding onto an investment for emotional reason rather than considering more practical applications for the inheritance (eg Anita with parent’s investments)
Cognitive Dissonance
The challenge of reconciling two opposing beliefs
Confirmation Bias
Natural human tendency to accept any information the confirms our preconceived position or opinion and to disregard any information that does not support that preconceived notion.
Diversification Errors
Investors tend to diversify evenly across whatever options are presented to them
Fear of Regret
Tendency to take no action rather than risk making the wrong one
(Mom and Ray with investments)
Gambler’s Fallacy
