Dean of Wall Street, Mr. Benjamin Graham stated in his popular book “The Intelligent
Investor” that markets are more psychological and less logical. Behavioral finance,
a relatively new field of finance, attempts to combine behavioral and psychological
theory with conventional economics and finance to provide explanations for why people
make irrational financial decisions.
According to conventional financial theory, the world and its participants are rational
human Being and strive to maximize their wealth prudently. However, there are many
instances where Emotion and psychology influence our decisions, causing us to behave
in unpredictable or Irrational ways.Simon Savage, co-head of European and global
long/short strategies at GLG Partners, a hedge fund manager owned by Man Group,
said:
“We were all born to be bad fund managers because of inbuilt behavioural biases,
which are present in everyone to various degrees. It’s through an awareness of them
that as a fund manager you can begin to build a defense mechanism to avoid these
vulnerabilities. Ignore them at your peril.”
Here are some of the main behavioural biases that investors need to look out for:
Loss-aversion bias:
Loss aversion refers to investor's tendency to strongly prefer avoiding losses to
acquiring gains. The fear of loss leads to inaction. Studies show that the pain
of loss is twice as strong as the pleasure of gain of a similar magnitude. Investors
prefer to do nothing despite information and analysis favoring a particular action
that in the mind of the Investor may lead to a loss. Holding on to losing stocks,
avoiding riskier asset classes like equity when there is a lot of information and
discussions going around on market volatility are manifestations of this bias. In
such situations, investors tend to frequently evaluate their portfolio’s performance,
and any short-term loss seen in the portfolio makes inaction their preferred strategy.
Confirmation bias:
Confirmation bias is the phenomenon that describes the tendency of people to prefer
information that validates their theses, hypotheses and beliefs independently of
its truthfulness.
Confirmation bias, also called my side bias, is the tendency to search for, interpret,
or prioritize information in a way that confirms one's beliefs or hypotheses. It
is a type of cognitive bias and a systematic error of inductive reasoning.
For example, when a trader buys a stock for a reason and that reason doesn’t work
out so the trader makes up another one for owning the position. Similarly, first
we make decision in mind and then find for the Information to justify that intuitive
decision.
Ownership bias:
Things owned by us appear most valuable to us. Sometimes known as the endowment
effect, it reflects the tendency to place a higher value on a position than others
would. It can cause investors to hold positions they would themselves not buy at
the current level.
Gambler’s fallacy:
Predicting absolutely random events on the basis of what happened in the past or
making trends when there exists none. It is the mistaken belief that if something
happens more frequently than normal during some period, then it will happen less
frequently in the future, or that if something happens less frequently than normal
during some period, then it will happen more frequently in the future (presumably
as a means of balancing nature).
Winner’s curse:
Winner’s curse is the tendency for the winning bid to exceed the worth of an item.The
person who wins the bid overestimates its worth the most, as they were willing to
go above and beyond what a presumably rational person is willing to bid. So, the
fact that they won means they paid more than the item is actually worth in the market,
as they pay more than other people have valued the item at.
Tendency to make sure that a competitive bid is won even after overpaying for the
asset. While behaviourally it is a win, financially, it may be a loss. In these
emotional and overwhelming situations, it can be difficult to make rational decisions
about an item’s value, and people often fall victim to the winner’s curse
Herd mentality:
In behavioral finance, herd mentality bias refers to investors’ tendency to follow
and copy what other investors are doing. They are largely influenced by emotion
and instinct, rather than by their own independent analysis. This guide provides
examples of how investors may succumb to herd bias
This is a common behavioral disorder in investing community. This bias is an outcome
of uncertainty and a belief that others may have better information, which leads
investors to follow the investment choices that others make. Such choices may seem
right and even be justified by short-term performance, but often lead to bubbles
and crashes. Small investors keep watching other participants for confirmation and
then end up entering when the markets are over heated and poised for correction.
Most of the individuals don’t go against the crowd as economist John Maynard Keynes
said:
“It is better for reputations to fail conventionally than to succeed unconventionally.”
Example
Crypto currencies have been in the trend for quite some time now. Names such as
bitcoin and Etherium have become popular. Many industrialists and popular business
figures are jumping on the bandwagon, Elon Musk being one of them. People know him
as a smart investor and a successful businessman, and naturally, the community will
believe that he knows something that they do not. Therefore, they tend to follow
his actions blindly.
Musk endorsed a popular meme coin which made the coin’s price soar to rocket highs.
The prevailing trend is that people invest in it whenever he puts up a tweet, and
when the effect wears off, the prices go down. Despite the creation of coin being
a joke, people invest in it because a famous and successful person invested in it;
for whatever reasons. This can and has led to many investors suffering losses who
had put in huge money to make a handsome profit.
Anchoring
Anchoring is a cognitive bias that describes the common human tendency to rely too
heavily on the first piece of information offered when making decisions. Investors
hold on to some information that may no longer be relevant, and make their decisions
based on that. New information is labeled as incorrect or irrelevant and ignored
in the decision making process.
Investors, who wait for the ‘right price’ to sell even when new information indicates
that the expected price is no longer appropriate, are exhibiting this bias.
For example, they may be holding on to losing stocks in expectation of the price
regaining levels that are no longer viable given current information, and this impacts
the overall portfolio returns. Actually, the decision should be made purely on the
basis of what price and value difference exist today in light of available information
rather than based on what the prices were in the past.
