Errors and emotions
Cognitive errors arise from faulty processing or beliefs and can respond to better information; emotional biases arise from feelings and can be harder to change through facts alone.
Anchoring relies too heavily on an initial number; confirmation bias favors supporting evidence and neglects disconfirming information, impairing forecast updates.
Portfolio consequences
Availability and representativeness can overgeneralize vivid events or short patterns; base rates and appropriately broad samples help challenge them.
Loss aversion can encourage holding losers or rejecting a sensible rebalance, while overconfidence can produce concentrated positions and excessive trading.
Practical interventions
Mental accounting separates economically connected holdings into buckets; evaluate aggregate risk so a safe label does not conceal leverage elsewhere.
Precommitted rebalancing, checklists and independent challenge can reduce process errors; observed market anomalies still require evidence beyond a story about one bias.
Formula and assumptions
Prospective return uses current opportunity cost; historical loss uses original cost
Original applied case: Recognize bias and design a decision process
- A position bought for 100 now trades at 70. An analyst expects 77 under an updated forward scenario.
- Forward scenario gain from today is 77/70−1=10%; the historical purchase price does not change this prospective arithmetic.
- Tax and alternatives still matter, but “sell only at my entry price” is not a complete investment thesis.
Errors to catch
- Do not assume: All emotional biases disappear after one statistics lesson.
- Do not assume: Confirmation bias gives equal weight to contrary evidence.
- Do not assume: A vivid recent event is always the best base rate.
