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”.
What is Loss Aversion?
- emotional bias where an investor finds the idea of losses twice as painful as the pleasure of gains
- core tenet of Prospect Theory
What is Overconfidence?
emotional bias where an investor has
unwarranted faith in his or her own thoughts
and abilities
What is Self-Control Bias?
- human tendency to focus on instant
gratification due to lack of discipline - consequently failing to act in the best interest of long term goals
What is Status Quo Bias?
an emotional bias where when faced with an array of options, an investor is predisposed to select the option that keeps conditions the same
What is Endowment Effect?
- an emotional bias where an individual assigns a greater value to an object already held or owned, or an object that he may actually lose
- example: investors may assign additional value to stocks they have inherited
What is Regret Aversion?
emotional bias where investors avoid taking decisive action because they are afraid that when looking back at the course they select, it will prove less than optimal
“Fear of making the wrong choice”
What is Affinity?
- an emotional bias where investors make decisions based on how they believe a product or service reflects their values
- example: individuals with affinity bias are prone to purchase stocks that reflect their self image
What is the Disposition Effect?
investors typically hold on to losing investments too long but sell winning investments too early.
The tendency to hold onto losing investments too long can be tied back to the so called “snake bit effect” where investors are seeking to avoid losses.
What is the Sunk-Cost Fallacy?
Investors may continue to hold an investment and even invest more (e.g., double down) in large part because of the time, effort and energy they have
already invested in the idea behind the investment. Thus, they are emotionally tied to the initial choice.
The sunk-cost fallacy is often tied back to the following biases: anchoring and status quo bias.
