Behavioral Finance: Introduction
Behavioral Finance:
• It is a concept developed with the inputs taken from
the field of psychology and finance.
• It tries to understand various puzzling observations in
stock markets with better explanations.
• The behaviour of individuals, practitioners, markets
and managers is sometimes characterized as
irrational.
Behavioural Finance: Introduction
Behavioural Finance:
• Behavioural Finance denotes the study of finance based
on credible assumptions about how people behave, often
confirmed by psychological experiments.
• Shefrin (2005) in his book on behavioural asset pricing
states ‘Behavioural finance is the study of how psychology
phenomena impact financial behaviour’.
Behavioral Finance: Introduction
Behavioral Finance:
• Some decisions are simple choices like, which brand
of toothpaste we will use, how hard we will study in
behavioural finance.
• Other decisions such as whether we should buy a
particular stock, how should we invest in tax saving
instruments, etc impact our financial well being.
Why Behavioral Finance??????
• Conventional" or "modern" finance is based on rational and logical theories,
such as the capital asset pricing model (CAPM) and the efficient market
hypothesis (EMH).
• These theories assume that people, for the most part, behave rationally and
predictably.
• One of the most rudimentary assumptions that conventional economics and
finance makes is that people are rational "wealth maximizers" who seek to
increase their own well-being.
• Behavioral finance seeks to explain our actions, whereas modern finance
seeks to explain the actions of the "economic man"
Behavioural Finance: Introduction
Nature
• Behavioral Finance is just not a part of finance.
• It is something which is much broader and wider and
includes the insights from behavioral economics,
psychology and microeconomic theory.
• The main theme of the traditional finance is to avoid all
the possible effects of individual’s personality and
mindset
Behavioural Finance: Introduction
Behavioural finance is divide it into two branches.
• Micro Behavioral Finance:
– This deals with the behaviour of individual investors.
– In this the irrational investors are compared to
rational investors (also known as homo economicus or
rational economic man)
• Macro Behavioral Finance:
– This deals with the drawbacks of efficient market
hypothesis.
– EMH is one of the models in conventional finance that
helps us understand the trend of financial markets.

• Behavioral Finance as a Science:
• Science is a systematic and scientific way of observing,
recording, analyzing and interpreting any event.

based on various theories.
• On this basis behavioural finance can be said to be a
science .
Behavioral Finance: Introduction
• Behavioral Finance as an Art
• In art we create our own rules and not work on rules of
thumb as in science.
• Art helps us to use theoretical concepts in the practical
world.
• Behavioural finance focuses on the reasons that limit the
theories of standard finance and also the reasons for
market anomalies created.
• It provides various tailor made solutions to the investors
to be applied in their financial planning.
• Based on above behavioural finance can be said to be
an art of finance in a more practical manner.
