Behavioral Finance Flashcards
Prospect Theory
more risk averse vs pleasure seeking by ratio of 2:1
• make decisions based on probabilities than potential outcomes
• loss aversion ties into this theory; attendance to feel impact of losses more than the pleasure of gains (asymmetrical S-shape)
• people make financial and investment decisions using mental shortcuts and biases (called heuristics)
Paradox of Choice
giving people more choice does not increase performance/satisfaction
• people easily overwhelmed with information
• often do nothing when conflicted
• optimal decisions are note made
Adaptive Market Hypothesis (AMH)
reconciles EMH with behavioral economics
• markets evolve over time as individuals use numerous heuristics/biases to make decisions
• opportunities for arbitrage; value in fundamental/technical/quantitative strategies
• survival is primary objective, profit and utility are secondary; innovation is key to survival and growth
Cognitive Dissonance
confusion/frustration when new info does not conform beliefs; hold losers, herd behavior, “different this time”
Conservatism Bias
cling to prior views at expense of new info, slow to change, under-react, ignore complex/conflicting information
Confirmation Bias
actively seek out information that confirms prior views, ignore conflicting info, under-diversified, pre-determined screen
Representative Bias
process new info using pre-existing beliefs, similarities to past events, flawed perception; gambler’s fallacy
Illusion of Control
think you can control investment outcomes, leads to overconfidence, excess trading, under diversification, limit orders
Hindsight Bias
perceive outcomes as if predictable, criticizing managers in out of favor asset classes
Mental Accounting
treat various sums of money differently, mental categorize, house money effect, sell at gain after draw down
Anchoring/Adjustment Bias
influenced by purchase price, cling to numbers when forecasting estimated returns
Framing Bias
respond to similar situations differently based on context which presented, risk tolerance questions, excessive risk aversion
Availability Bias
easily recalled/recent outcomes perceived as more likely to occur; retrievability, resonance, categorization, narrow range of experience
Self-Attribution Bias
ascribe successes to talent/failures to outside influences; under diversification, excessive risk-taking
Outcome Bias
make decisions based on past outcomes rather than process through which outcome occurred, focus solely on track record
