Group Profile
3. Research indicates on average,
individual investors under-
perform relevant benchmarks
S&P 500 has
generated annualized
returns of 9.9% but
individual investors
have only 2.5%. More
than 7% lower !!!
4. Why does that
happen?
Overall, the poor performance by
individual investors can largely be
explained by some behavioral
biases that influence their
investment decision-making
processes.
So…the investor’s chief
problem – even his
worst enemy – is likely
to be himself.
5. In which shares are
you going to
invest?
In GP, Square, ACI,
BAT and Summit
power
WOW, Have you
done your
investment
research?
Do we need that?
They are popular
company.
Familiarity bias
6. My friend is making
more money .
My return should be at
least as much as his
return.
Relative wealth
bias
7. I am going to sell my wining
stocks
My stocks are not doing well
and I am going to retain
those.
Hanging on to
losers and
disposition
effect.
8. I am going
to call the
day off.
Hopefully it is
going to be a
good day for
treading stock
Investors
attention, mood
and experience
9. Herding effect: Investors make similar trading errors
because they are actively trying to follow each other’s
behavior.
SellSell
Sell
Sell
10. Overconfidence Bias: Optimistic assessment of one’s
knowledge and control over a situation.
According to my
analysis share
price will go up
for sure.
11. Over optimism Bias: Overestimating the likelihood of a good
outcome and underestimating the likelihood of a bad outcome.
90% chance that
stock price will go up
& 10% chance that
price will fall.
12. Mental accounting: Tendency to separate money
based on subjective criteria often impacting financial
decisions and wellbeing
I’ve won a
gamble and
invested the
money in
Junk bond.
I’m going to
invest my
savings in
T-bill
13. Recency bias
Law of small
number bias
As market is
bullish for
last few
weeks, so I
am going to
invest
14. I am going to hold
X’s company’s
share
Why, don’t you know that a
major project of this
company has failed
recently. This may affect
its share price.
I don’t think this
will affect the
share price much.
Anchoring bias
15. Prospect theory: Value gains and losses differently.
Feel more pain in losing than joy felt in receiving equal
amount of gain.
Option A: NO payoff
Option B: 50% Gain $50 and 50%
Loss $50
Net result: 0={.5*50+.5*(-50)}
16. Suggestions to overcome those biases.
Follow passive investment strategy: Invest in market
portfolio.
Seek diverse outside opinion to counter our overconfidence
Stop watching news daily because watching news every day causes investors to react
emotionally, rather than analytically and strategically.
Search relentlessly for potentially relevant or new disconfirming evidence.
Follow momentum strategy that says to sell stocks that have low returns and buy
stocks that have past high return.
