Section III.B. Flashcards
What is Prospect Theory?
–
A descriptive theory based on experimental evidence. (Kahneman
and Tversky 1979)
–
Most individuals are more risk averse vs. pleasure seeking by a ratio
of roughly 2:1.
What are key tenets of Prospect Theory?
- People make decisions based more on probabilities than potential outcomes
- People make decisions using mental heuristics (e.g., mental shortcuts and biases)
- Loss aversion: the tendency to feel the impact of losses more than gains
- This value function can be illustrated graphically using an asymmetrical s shaped curve
What is Cognitive Dissonance?
confusion or frustration that arises when an individual receives new information that does not match up with or conform to preexisting beliefs or experiences
“Beliefs don’t match up with actions”
What is Conservatism?
- bias where people cling to their prior views or forecasts at the expense of acknowledging new information
- individuals are inherently slow to change
What is Confirmation Bias?
cognitive bias where people observe,
overvalue, or actively seek out information
that confirms what they believe while ignoring
or devaluing information that contradicts their
beliefs
What is Representativeness?
- a cognitive bias through which individuals process new information using pre existing ideas or beliefs
- an investor views a particular situation or information a certain way because of similarities to other examples even if it does not really fit into that category
What is “Illusion of Control’?
a cognitive bias where people believe they
can control or influence investment outcomes
when in reality they cannot
What is Hindsight Bias?
- cognitive bias where investors perceive investment outcomes as if they were predictable, even if they were not
- sometimes gives investors a false sense of security when making investment decisions leading them to excessive risk taking
What is Mental Accounting?
a cognitive bias in which individuals treat various sums of money differently based on where these monies are mentally categorized (e.g., retirement, college, etc.)
What is Anchoring?
- a cognitive bias where investors are influenced by purchase point or arbitrary price levels and cling to these numbers when deciding to buy or
sell and investments - individuals often rely too heavily on certain information (often the first data points received) when making decisions
What is Framing?
cognitive bias where an individual responds to similar situations differently based on the context in which the choice is presented
What is Availability?
a cognitive bias where easily recalled outcomes (often from more recent information) are perceived as being more likely than those that are harder to recall or understand
What is Self-Attribution?
a cognitive bias where people ascribe
successes to their innate talents and blame failures on outside influences
What is Outcome Bias?
a cognitive bias in which people often make decisions or take action based on the outcome of past events rather than by observing the process by which that outcome occurred
What is Recency Bias?
- investors tend to believe that patterns, trends and movements in the recent past are likely to repeat themselves
- individuals put too much weight on and make decisions based on inputs and feedback they have recently received
“Recent results, indication of upcoming results”.
