Behavioral - Reverse Cards Flashcards
Experiences and biases that can facilitate problem-solving and probability judgements.
Examples in daily life are “trial and error” and “rules of thumb”
These strategies are generalizations that can result in inaccurate or irrational conclusions.
Heuristics
The study of how psychology affects finance.
Behavioral Finance
The tendency of investors to become attached to a specific price as the fair value of a holding.
Anchoring
Holding onto an investment for emotional reasons rather than considering more practical applications.
Attachment Bias
My grandfather left me this stock so I can never sell it.
Attachment Bias Example
The feeling that because you own an asset, it is more valuable and special since it is yours. In reality, you might not even purchase the asset if you didn’t already own it.
Endowment Bias
You inherited the family summer home and wouldn’t ever sell it even though it has become a money pit.
Endowment Bias Example
The challenge of reconciling two opposing beliefs
Cognitive Dissonance
Remembering the positive part of an experience but forgetting the negative.
Cognitive Dissonance Example
The natural human tendency to accept any information that confirms our preconceived position or opinion and to disregard any information that does not support that preconceived notion.
Confirmation Bias
An investor hears about a hot stock from an unverified source and is intrigued by the potential returns. That investor might choose to research the stock in order to prove its touted potential is real by focusing only on the positive aspects of the stock and disregarding any negative aspects.
Confirmation Bias Example
Investors tend to diversify evenly across whatever options are
presented to them.
Diversification Errors
Consider the style-box mania where investors feel compelled to own a piece of each box in order to be diversified. 401K participants tend to spread their money across whatever options they have.
Diversification Errors Example
The tendency to take no action rather than risk making the wrong one.
Fear of Regret
An investor holds onto a stock that’s losing value, because if they sold and it rebounded, they would feel even worse.
Fear of Regret Example
Cognitive bias, in which a person makes decisions based on whether the various options are presented in a positive or negative way, meaning individuals can tend to overlook factual data. The person is more affected by how the information is worded rather than the actual information. This can manifest itself in investment decisions.
Framing Effect
An individual erroneously believes that the onset of a certain random event is likely to happen following an event or a series of events.
Gambler’s Fallacy
Some investors believe that they should liquidate a position after it has gone up in a series of subsequent trading sessions because they do not believe that the position is likely to continue going up.
Conversely, other investors might hold on to a stock that has fallen in multiple sessions because they view further declines as improbable. The solution is investors should base their decisions on analysis.
