ABSTRACT:
The investor is a human and to err is just
natural. Traditional finance assumes investors behave rationally. Investors
process new information quickly and correctly, whereas
the evolving field of behavioral finance assumes that investors suffer from
cognitive and emotional biases which may lead to irrational decision making.
Investors may overreact and under react to new information. Behavioral finance
is a field of financial thought that examines investor behavior and how this
behavior affects what is observed in the financial markets. The behavior of
individuals, in particular their cognitive biases, has been offered as a
possible explanation for a number of pricing anomalies.
In financial markets, active and passive
investors are bound to react to certain information in their own manner and the
cognitive and emotional biases are distinct to both of the investors. This
paper is an attempt to explore the behavioral biases of active investors in
equity markets in Jaipur. In this piece of work, the
existence of behavioral biases of active investors is observed such as herd
behavior, hindsight bias, cognitive dissonance, disposition bias and the
gambler’s fallacy. The demographic factors such as financial literacy and years
of investment experience in the stock market were linked.
KEYWORDS: Cognitive Bias, Emotional Bias, Pricing
Anomaly, Financial Literacy, Herd Behavior, Cognitive Dissonance, Disposition
Bias, Gambler’s Fallacy, Hind Sight Bias.
The paradigm of Efficient
Markets was advanced by Eugene Fama in the 1960’s
which asserts that it is impossible to beat the markets as all available
information is reflecting in the prices of the securities. As harmonizing with
this hypothesis, it is stated that all the securities are right there with fair
prices, eliminating the concept of underpriced and overpriced security, thus
there is no chance for earning the abnormal returns (investopedia.com).
In 1970’s Eugene Fama published a review for the hypothesis. This includes
three forms of the market-Weak, Semi-Strong and Strong. Weak Form asserts that
past information about stocks reflects in present stock prices. Semi-Strong
Form asserts that prices reflect past information very quickly and thus not
generate any abnormal return and Strong form asserts that markets are full of
information and because of that an investor cannot earn the return excess from
market regularly as stock market discounts every bit and bytes of information.
Contrary to this, if securities
would have properly priced then there will not be any chance for earning the
returns. But in general, investors are not rational, but quasi-rational or
irrational. This notion was expressed by the field of behavioral finance as it
comprehends the art of behavioral biases amongst the investors. The field of
behavioral finance is debating from long that it is possible to beat the market
layered with the fact of active investment strategy. The large body of
researchers and academicians from so long is contradicting with the evidences
that investors like Warren Buffet have been beating the market. The great
volatility in markets substantiates that the securities are not fairly priced
and they deviate from their intrinsic value.
Here intervene the cognitive
and emotional biases which distort the investment decision making process.
Cognitive biases are connecting with faulty reasoning and through education it
can be corrected. Emotional biases on the other side of the coin are lacking
the criterion of self control or overconfidence and are severe to correct (NAAIM, 2013).
REVIEW OF RELATED LITERATURE:
The roller coaster of cognition
and emotions paves the way for active and passive investors and the riding
cycle of investment moves accordingly. The dimensions for active and passive
investor differ as active investors try to obtain the return from the market.
They keep on updating themselves with the recent happenings in the market and
they do not hold globally diversified portfolio. As these investors’ wishes to
beat the market, they rely to outperform the market in the short term and
believe in technical analysis rather than fundamental analysis (Stanley, 2012).
Passive investors work on daily
price fluctuations, whereas the passive investors get good returns in a long
while with a minimum of involvement by choosing those stocks which are having a
decent track record and by diversifying the portfolio, so that risks can be
eliminated (Harvey).
Behavioral biases are connected
with the type of investor which ultimately distorts the investment decision
making process. On the continuum of risk tolerance, the passive investors are
near to zero, whereas the active investors are more towards the high risk
exposure. The passive investors are more emotional for their hard earned money
and keep their choice static for a long period of time for earning the returns,
whereas active investors wish to time the market in the short run and want to
earn the abnormal return in the near span of time. They endure themselves with
the expressions of overconfidence and illusion of control which makes them
behave in a faulty manner (Pompian, 2006)
The active and passive
investors are distinct from each other and cognitive and emotional biases are
defined for both of the types to a great extent in the work of Pompian, 2006. These
emotional biases are unstable, which cannot be rectified but the cognitive
biases are generally stable and can be eliminated by giving due thoughts to a
certain situation.
Baker, 2010, supported that passive investment is consistent with the
Efficient Market Hypothesis (EMH) but not in the line with behavioral
perspective. (Thaler, 2005), propped up
with a thought that, considering the heuristic not any individual can predict
the movement of stocks. (Wärneryd, 2001), concluded
that passive investors are more successful than active sophisticated
investment. These investors maintain their financial security investment for a
long while with a shorter margin in the short term time frame. In contrast with
active investors, passive investors do not try to beat the market and stays
passive with respect to volatility in the markets.
In contradiction with active
investment, passive investment exemplified with heuristics and frugal decision
making. Although this minimizes the effect of emotional drivers in decision
making, but this might result in bubbles and price burst as people stop giving
ear to the herding which at the point of saturation fractures in a severe way.
RESEARCH METHODOLOGY:
The study from the perspective
of descriptive research used the questionnaire instrument for collecting the
responses of investors. Statistical population of the study was the active
equity investors of stock market of Jaipur city. The
questionnaire included the dimensions of demographic factors such as financial
literacy and years of experience in the equity investment and behavioral biases
such as gambler’s fallacy, disposition effect, cognitive dissonance, herd
behavior and hindsight bias. The questionnaire was self evaluated in which
investor was given a certain situation and their responses were scored. For
analysis, the administered points of each of the biases were taken. The
objective of research is to explore the behavioral biases of active investors
in association with two demographic factors.
Since this study applies
primary data, the tool was designed and validated. The tool was tested on 20
investors of Jaipur city taken randomly. The
reliability analysis was conducted for consistency and Chronbach
alpha was found 0.787. After cleaning
the data, the analysis was executed on 146 active equity investors of Jaipur City. Research variables were identified and defined
and were examined for normality and it was found non-normal. Hence, we used the
non-parametric methods for testing the statistical significance. Underneath

The analysis was conducted
through SPSS-PASW-18 trial version. The results are underneath
The Man-Whitney U test was used
to compare the behavioral biases of two groups of active investors on the basis
of financial literacy.

It was found that the average
herd behavior is significantly different in both the groups (i.e. P Value <
0.05) and it was found more in non-financial literate group. Similarly, the
difference was also observed in gambler’s fallacy and the visible impact was
seen in non-financial literate group. This implies that herding and gambling
tendency exists in non-financially literate group as these investors’ wishes to
follow the crowd because of the limitation of their knowhow of stock market and
they also involve themselves in gambling without understanding the tandem of
movement of the stock market. There was no significant difference observed in
the other three biases with the financial literacy. (Refer-Table 1)
On the other keen dimensions of
hindsight and cognitive dissonance biases, the investors who are not
financially literate were more prone, but it was quite of interest that
disposition effect was more observed in financially literate investors.
Resistance to panic is the crucial issue for an investor from many decades, so
as in this survey, it is explored that investors generally sell the winners and
hold the losers. Thus the first null hypothesis was rejected as it was observed
that there is a significant difference exhibited by both financially literate
and illiterate investors.
The Kruskal-Wallis
test was used to test the difference in behavior biases as there were three
groups in the years of experience in market and also post-hoc analysis was
conducted for the variables which have the p-values of Kruskal-Wallis
test significant.
It was found that the herding
behavior and the gambler’s fallacy with years of experience in the market is
significantly different in all the groups and it was found more in third
experienced group and least in the first group. This implies that herding
behavior is maximum in the group of >10 years and 3 to 5 years. The initial
phase of herding and gambler’s fallacy and having an enough experience in
equity markets both are full of herding and gambling tactic. It can be inferred
that primary experience in the stock market have an obvious notion of the herd
instinct and on the latter on stages when people imbibed themselves with enough
experience they are influenced by the disposition effect too i.e. to sell the
winners early and retain the losing stocks in the portfolio. This behavior
sways that fear and loss aversion attitude of investors let them behave in that
direction for following the crowd.

For gambler’s fallacy, the
difference is lesser in the later stages of experience in the market. This
entails that as investors’ starts understanding the basics of stock market, the
behavior of gambling converts into the notion of cognition. There was no
significant difference observed in the other two biases i.e
hindsight bias and cognitive dissonance with years of experience in market.
(Refer-Table 2). It also resulted in rejecting the second null hypothesis.
CONCLUSION:
It can be concluded that
herding and gambling are prominent in the active equity investors of Jaipur city. This is to recommend that investors should
understand the rationale of economic decisions and should understand the emotional
and the cognitive tilt to better take the meticulous investment decisions.
