expanding field known as behavioral finance is beginning to take
hold which demonstrates that psychology plays a significant role
in how investors make decisions. Historically, the impact of
psychology and how it relates to decision-making has been mostly
ignored. Studies by Richard Thaler of The University of Chicago
and Daniel Kahneman of Princeton clearly demonstrate that investors
behave highly irrationally and make predictable errors. These
investment errors can wreck havoc on an investment portfolio
and upon the investor's ability to achieve long-term financial
goals. Overconfidence Psychologists
have found that people become overconfident when they experience
success. i There
are two main sources of overconfidence bias. The first relates
to the fact that most people consider themselves to be better
than average in most things they do. For example, 80% of drivers
contend that they are better than "average" drivers.
ii Is
that really possible? Avoiding Overconfidence Let history be your guide and keep things in perspective. The late 1990's weren't the first time that people got caught up in investment "mania", only to watch the speculative bubble burst and suffer significant losses. It also happened with the railroads in the early 1900's, radio broadcasting in the 1920's, as well as oil and gold stocks in the early 1980's. In each case, investors thought; "This time is different, it's a new economy." When the next investment mania occurs, keep things in perspective and ask yourself, "Is history repeating itself?" |

Establish an investment policy statement. An investment policy statement determines what percentage you will invest in asset classes such as stocks, bonds, and cash. For example, based on your risk tolerance, you may determine that 60% of your assets should be in stocks, 30% in bonds and 10% in cash. Assuming each category is diversified, studies have demonstrated that you can expect a certain range of returns and volatility over the long-term based upon your allocation. Establishing and monitoring the above parameters can help you limit your emotional involvement and avoid the overconfidence bias. When the market surges ahead, and your confidence increases, check your investment policy statement to make sure you stay on course. Availability Bias Availability
bias causes people to base their decisions on the most recent
and meaningful events. The brain views ancient history as anything
that happened more than a couple of years ago. For example, if
you were in a car accident within the last week, it would be
a natural tendency for you to drive extra cautiously for the
next month. However, as time passes, your driving will likely
return to its original state. Availability bias causes investors
to over-react to market conditions whether it be "positive"
or "negative". As illustrated earlier, in the late
1990's, investors got caught up in tech mania, which caused them
to disregard the risks. This was followed more recently by troubling
events in the economy, which caused investors to lose confidence
and over-focus on the short term, negative results. It is natural
for people to get lost in the moment. Availability bias also
causes people to think that events that receive heavy media attention
are more important and pertinent than they are in actuality.
Unfortunately, much of the financial information received on
a daily basis is mostly noise and not particularly important.
In fact, the information is often inaccurate, based on multiple
opinions, outdated or downright confusing. Coupled with too much
information, many investors overlook the fact that they often
lack the training, experience and objectivity to interpret the
massive amount of information available. This causes many investors
to get a false sense of security in thinking they are well-informed
investors. Avoiding Availability Bias Focus
on long-term results and avoid getting swept away by your emotions
and the latest mania whether it be positive or negative. Mental Accounting What
behavioral finance professionals have called "mental accounting"
is where investors mentally compartmentalize money such as individual
stocks, bonds, real estate or cash. This causes investors to
lose sight of the big picture and instead focus on each specific
investment and feel pleasure or pain depending on a particular
investment's performance. How to
Avoid Measure
your investment success by the performance of your overall assets
versus measuring success by a particular asset category such
as stocks, bonds, or real estate. Remember, it is your overall
financial picture that matters at the end of the day, not how
one asset category has done. Conclusion It
is increasingly more apparent, if inventors are to achieve optimal
returns, they cannot afford to overlook the role that psychology
plays in the decision-making process. Recognizing that psychological
biases exist and taking proactive steps to overcome them will
undoubtedly increase the investor's ability to achieve their
long-term financial goals. i Paul Presson and Victor Benassi, 1996, "Illusion of Control" Journal of Social Behavior and Personality 11(3): 493-510. ii John R.
