Behavioural Investing:
How to Succeed Despite Love, Fear and Greed
John Price, Ph.D.
You ache all over. Your head is throbbing. One
minute you are sweating like you have been playing tennis
for an hour, the next you are shivering. We are all too familiar
with the symptoms of the flu. When it hits us there is little
we can do except grin and bear it until it passes.
Not so clear are the symptoms of chronic diseases.
We have the vague feeling that something is not quite right.
Less energy, slight twinges. Every thing takes more effort
to do, and the results rarely meet our expectations.
The same difference exists in the share market.
On the one hand, we have acute illnesses like the collapse
of Enron or WorldCom In the USA or HIH and One-Tel in Australia.
When you are hit by it, there is little you can do except
bear the pain.
On the other hand, just as with our physiology,
there are also chronic diseases in investing. These can be
even more damaging to your investment health than acute diseases.
The symptoms are often a vague feeling that
something is wrong. Or, more seriously, we may not even know
that we have been infected. But the chronic diseases of investing
eat away at your investing success, day after day, week after
week, year after year.
No matter how hard you try, your returns are
just not what you hoped or expected.
As for medical chronic diseases, there are many
classes of chronic investment diseases. I am just going to
mention the diseases in one of these classes, the behavioural
chronic diseases of investing.
I shall mention six of these, namely Get-Evenitis,
Consolidatus Profitus, Tradophilia, King Kong Syndrome, Lotto
Syndrome, and Success Addiction.
The basis of all these diseases is fuzzy thinking.
So, before explaining the diseases, I would like to give an
example of fuzzy thinking.
You are going to be given two scenarios and
in each scenario you will be given two alternatives. Choose
one of the alternatives in each scenario. Don't spend too
much time on it. Just choose the alternative that first comes
to your mind.
Scenario 1 In addition to whatever
you own, you have been given $1,000. Which of the following
two alternatives would you choose?
A1: A sure gain of a further $500,
OR
B1: A 50% chance to gain a further $1,000
and a 50% chance to gain nothing.
Remember what your choice was. Better yet, write
it down and try to put it out of your mind.
Scenario 2 In addition to whatever
you own, you have been given $2,000. Which of the following
two alternatives would you choose?
A2: A sure loss of $500,
OR
B2: A 50% chance to lose $1,000 and a
50% chance to lose nothing.
What was your choice this time? Were your two
choices the same or different?
Don't read on until you have made your choices.
Did you think the two scenarios were different
or the same? It comes as a suprise to most people to learn
that technically they have exactly the same cash flows.
In both cases if you choose the first alternative
you have a sure gain of $1,500. For example, in Scenario 1
the first alternative is $1000 + $500 = $1,500 and in Scenario
2 the first alternative is $2,000 - $500 = $1,500.
An analysis of the second alternative in both
Scenarios gives a 50/50 chance of gaining $2,000 or of gaining
$1,000.
Even though technically the same, most people
choose the first alternative in Scenario 1 and the second
alternative in Scanario 2. (When these scenarios were presented
to two groups of subjects by researchers Kahneman and Tversky
in 1979, they found that 84% of the subjects chose A1 in the
first scenario while 69% chose B2 in the second scenario.)
The explanation for this is that in the first
scenario people favoured the first choice because they did
not want to gamble when the expected return of $500 for the
gamble was the same as the guaranteed return of $500 for the
sure profit.
In the second scenario, people favoured the
gambling alternative because they saw it as a way of avoiding
the sure loss of the first alternative.
Another way of explaining this is that people
do not like to lose and will often gamble to avoid this occurrence.
On the other side, people are less likely to adopt a gambling
strategy in the hope of making an excess profit.
Get-Evenitis
What happens when you buy a stock and it drops by 30 percent?
Do you sell or do you hang on hoping that it will come back
to its original price? If you usually hang on, then you may
be suffering from get-evenitis, a highly contagious disease
particularly among males.
If you buy XYZ for $20 and it drops to $12,
you now own a $12 stock. It does not matter how it arrived
at this price. The question now becomes, "If I had $12,
would I buy a unit of XYZ or would I buy something else?"
If the answer is to buy XYZ, then hang on to it. Otherwise
sell it. Unfortunately our ego will goad us into all sorts
of rationalizations why we should not sell at a loss.
We want to be able to say, "It's only a
paper loss. Don't worry. It will come back." Worse than
having our teeth pulled is being forced to utter "I made
a mistake." Even "There was a downturn in the market
which caused XYZ to go south" is hard for most of us
to say. Just as in real life, sometimes we have to face our
mistakes and accept a loss before we can move on.
In 1995 Nicholas Leeson became famous for causing
the collapse of Barings Bank, his employer. Over the previous
years he had some serious losses. Instead of admitting them,
in his own words, he "gambled on the stock market to
reverse his mistakes and save the bank." But things just
got worse and he ended up losing US$1.4 billion.
It is unlikely that any of us are going to catch
such an acute case of get-evenitis. More likely it will be
a low-grade infection that eats away at our investing profits.
Consolidatus Profitus
Get-evenitis has an associated disease called consolidatus
profitus. Where you see one, you usually see the other. Sufferers
of consolidatus profitus are often heard intoning "You
can't lose money by taking a profit."
You may not lose money for that particular stock,
but in the end what makes the difference is what we do with
our profits. What if we put the money from the sale into a
stock that is a major underperformer? We may be able to say
that we made a profit on a particular stock. What we are not
saying is that our portfolio went down because of the way
we spent the profits.
If ABC goes from $20 to $30, then you now own
a $30 stock. In the same way that you examined the loser above,
think what you would do with $30. If you would buy ABC for
$30, then keep the stock. If not, then sell it.
Of course, in real life things are a bit more
complicated since we have to take into account transaction
costs and taxes. But I think the general idea is clear-evaluate
your stocks on what return you expect to get from them in
the future, not on what they have done in the past.
Just how widespread are these diseases follows
from a large-scale study carried out by Terrance Odean of
the University of California in Davis. Reporting in the Journal
of Finance, 1998, he found that people tended to sell winners
and put the money into stocks that performed less well. Overall
he found that people would have been better to sell their
losers and keep their winners. Instead, they did the opposite,
namely they kept their losers and sold their winners.
To get a rough idea of the size of the losses,
imagine an investor that has two stocks to sell, one a past
winner and the other a past loser. Using data from Odean's
study, the average return on the past winner over the next
year was 2.4 percent above the market average compared to
a 1 percent loss on the past loser.
This means that holding on to your winner would
put you 2.4 percent ahead of the market during the next year.
In contrast, holding on to the loser would put you 1 percent
behind the market. But this is just what the average investor
did. On average, investors choose to sell their winners more
often than their losers.
Tradophilia
This is an infatuation with the thrill of trading. Barber
and O'Dean showed that there is a inverse correlation between
the number of trades a person made each year and how well
he or she performed in the market. In other words, on average
the more trading the lower the profit even when the transaction
cost are taken into account.
King Kong Syndrome
In July 1993, Robert Citron, the treasurer of Orange County,
California, predicted that interest rates would not rise.
When asked how he knew this, he replied, "I am one of
the largest investors in America. I know these things."
Within a little over a year it was public knowledge that Citron
was deluding himself. His prediction of how interest rates
would move was wrong, his error causing the Orange County
Investment Pool to lose $2 billion forcing the County into
bankruptcy.
This is an extreme example of what I call the
King Kong syndrome, the disease of arrogance and hubris.
Lotto Syndrome
State run lotteries hit on a goldmine when they allowed
the participants to choose their own numbers rather than be
simply given a ticket. With this small change in the way people
can choose their tickets they now feel in control. They can
choose their own numbers and so have the illusion of increasing
their chances of winning. This illusion of control, as it
is referred to by the psychologists, leads to overconfidence.
We see examples of this illusion of control
in people collecting all sorts of financial data whereas there
is no evidence that much of this data has anything to do with
share performance.
Success Addiction
Our irrational love of success can cause us not to face
the fact that we may have made a mistake.
Remedies
We all have these investment diseases to varying degrees
and perhaps it is impossible to be completely free of them.
One of the best ways I know of strengthening our immune systems
so that the diseases are kept at a tolerable level is to keep
a stock book. Before you buy a stock in a company write down
some of its key features with particular emphasis on those
things that you consider most important for your decision
making process.
Peter Lynch was a great advocate of recording
his thoughts on different companies. When he was the manager
of the Fidelity Magellan Fund, Lynch kept a series of notebooks
in which he wrote down information on companies that he analysed
or visited. He also required that his advisors be able to
make brief presentations on any companies that they thought
should be considered for the fund. Perhaps you could try this
with your spouse or a friend.
A pilot friend of mine says that his rule for
when there is a difficult situation is to "put your seat
back a few notches." This means to sit back and try to
take a calm and more dispassionate view. This seems like pretty
good advice to follow each time we are about to buy, or sell,
another share. This is the advantage of the Valuesoft.
It provides proven steps to locate quality companies at excellent
prices while at the same time filtering out the over-priced
and speculative companies.
