Behavioral finance is
descriptive - it tries to explain observed investor decision making

Risk-neutral (shape of utility function)
Linear
Framing bias
person’s inclination to interpret the same information differently depending on how it is presented
Bounded rationality
investors attempt to make the most rational decision possible based on the amount of information they deem satisfactory. Satisficing.
Framing bias
person’s inclination to interpret the same information differently depending on how it is presented
Availability bias
refers to the was with which information is attained or recalled

- Behavioral portfolio theory
- Adaptive markets hypothesis
Adaptive Markets Hypothesis
Adapt of perish.
Behavioral Portfolio Theory
Pyramid - layers, ignores correlation between layers. Low priority goals can be funded with high risk assets. High priority goals can be funded with low risk assets.
Cognitive Error: Conservatism
an initially rational view is maintained even when new information contradicts. FLAW: slow to update views and may hold securities longer than rational
Cognitive Error: Confirmation
new evidence is sought or used to support an original view. FLAW: thought processes or screenings are signed to find supporting information and ignore contradictory information, which can lead to under-diversified portfolios or concentration in employer stock
Cognitive Error: Representativeness
New evidence is classified and interpreted based on past classification or experience FLAW: attach to much emphasis to data covering only a short time period or immediately reclassify based on the new information without doing a full analysis
Cognitive Error: Illusion of Control
Individual incorrectly thinks they can control results. FLAW: trade too frequently and under diversify
Cognitive Error: Hindsight
Selectively remember what was done or known in the past. FLAW: overestimate ability to take too much risk
Cognitive Error: Anchoring and adjustment
subsequent adjustment for new information are around the initial “anchor” point. FLAW: focus on initial anchor point results in insufficient adjustments
Cognitive Error: Mental Accounting
Money is treated differently based on how it is categorized
Cognitive Error: Framing
Data presentation order affects the decision
Cognitive Error: Availability
Probability estimates are based on ease of recall. FLAW: Making decisions base on what is familiar, failing to diversify, results in suboptimal asset allocation.
Emotional Bias: Loss-aversion
Hold onto losers, selling winners. Disposition effect.
