Mental shortcuts for decision-making sometimes
trip us when analysis is warranted
Policy statements, plans and strategies can help keep investors on target.


Many-do it-yourself investors wonder why they often end up buying high and selling low. It's probably not for lack of intelligence. Bad judgments can arise if investors are not introspective about their real motivations for selecting a time to buy or sell, or any specific investment.


Psychologists have identified a number of common biases guiding the investment decisions of less experienced investors.   If you are wondering whether the latest crisis in world events should guide a specific buy or sell decision, take a look at this list and reflect first what other motivations may be prompting you.


Reasoned investing usually does best within the framework of a plan or investment policy statement. Then the investor can calibrate individual choices to fit with the overall strategy and timeline for accomplishing specific goals. Need help? I am happy to talk.


Most Common Behavioral Biases in Investors


Ambiguity Aversion

Dislike of ambiguity, masked as risk aversion, drives decisions.

Anchoring and Adjustment

Latching on to a specific price and make subsequent investing decisions based on that, for example, "I will sell (or buy) abc stock when it reaches a certain price."


Estimating the probability of an outcome based on how prevalent or familiar that outcome appears in their own lives.

Cognitive Dissonance

This happens when newly-acquired information conflicts with a person's understanding or beliefs. Investors with this tendency often go to great lengths to rationalize their investment decisions.


Holding perceptions and emphasize ideas that confirm their beliefs, while devaluing information that contradicts their beliefs.


Clinging to prior views of forecasts and resists new information.


Endowing assets that one owns with higher value and sets a higher minimum selling price for those assets than what one would be willing to pay for the same or corresponding assets.


Responding to various situations differently based on the context in which the choice is presented or framed.


Perceiving an event to have been predictable, even if it was not.

Illusion of Control

Believing  one can control or at least influence outcomes when, in fact, one cannot.

Mental Accounting

Tendency to evaluate economic outcomes based on the origin of the money (e.g., work, inheritance, bonus, etc.) rather than on a holistic view of the assets.


Overly optimistic about the markets, the economy and the potential for positive performance of their investments.


An unwarranted faith in one's intuitive reasoning, judgments and cognitive reasoning as well as an overestimation of their own predictive abilities and the precision of the information on which they base their decisions.


Recalling and emphasizing recent events and observations more prominently than those that occurred in the near or distant past.

Regret Aversion

Avoiding decisive action because of the fear that whatever course is taken will prove less than optimal.


Perceiving probabilities and odds that reinforce their own pre-existing ideas even when they are statistically invalid.


Crediting one's successes to one's own talent or foresight, while blaming failures on outside influences, such as bad luck.


The human tendency to consume today at the expense of saving for tomorrow.

Status Quo

Predisposition to elect whatever option ratifies or extends the existing condition.
