Being Right and
Making Money Are Not Equivalent
By Van K. Tharp, Ph.D.
At investment
conferences, the hottest speakers are those who provide information
about high probability entry techniques. If you say, "Trade with the
odds on your side" and show someone a technique that is right 75% of
the time, you’ll get a large audience. Yet most techniques of this
nature usually have big losers and may not even have a positive
expectancy. Nevertheless, being right 75% of the time is all is
takes to get people to trade them.
How important is it
for you to be right? Let’s say I could guarantee that you would make
money by the end of the year—lots of money—but you would probably
lose money on 90% of your trades. Would you like that? Could you
tolerate that? Would you accept that? Most people would probably
answer "no" to all three questions. And if that is you, you probably
are denying yourself the opportunity to make money simply because
being right is more important than making money.
Some of you might be
saying, "How could you be wrong 90% of the time and still make
money?" The solution goes back to the golden rule of trading, "Cut
your losses short and let your profits run." Let’s say that 90% of
your trades lose money and that your average loss is $100. On the
year you make 100 trades so you end up losing 90 of them for a total
loss of $9,000. However, let’s also say that your average winning
trade is a big R-multiple. It’s an R-multiple of 100 or a $10,000
winner. You have ten of those in a year, so you end up making
$100,000 on your winning trades. If you subtract your winnings from
your losses, you’d end up with a profit of $91,000 at the end of the
year. You make $91,000, yet 90% of your trades are losers.
My guess is that 99%
of the trading population could not trade a system that would
produce those kind of results. The reason is because they don’t get
to be right enough. They have too many losing streaks. They have
losing streaks that are longer than five in a row. Most people
cannot tolerate long losing streaks. When they occur, they totally
abandon what they are doing. In such a system you could easily have
25 consecutive losses. At that point you become certain that your
system is broken, and you try something else.
Let’s look at the
opposite end. Suppose you got to be right 90% of the time. Suppose
your average win was $100 and that your average loss was $2,000.
This means that you’d have a total of $9,000 in winnings and $20,000
in losses. You would lose $11,000. Would people trade that system?
Yes, they would. They would probably trade it for a number of years
until they went bankrupt. Why? Because they get to be right most of
the time and that is very rewarding.
You might be saying,
but how could people possibly tolerate losses of $11,000 after 100
trades? It is easy; they turn the losing trade into a long-term
investment in their mind and say, "it’s only a paper loss." For
example, I’ve had workshop attendees who were probably way above
average in terms of sophistication. However, I asked them to raise
their hands if they had an investment in their portfolio that was
only worth 50% or less of what they paid for it. Eleven people
raised their hands—over a fourth of the class. And my guess is that
among the overall population of investors, most people are sitting
on a number of big losers, hoping they will come back. Why? Because
they cannot stand to be wrong on an investment and they are waiting
to be right on those losing trades.
What is the cost of
having losing investments in your portfolio? It’s major. First, you
are using valuable capital up with nonproductive investments.
Second, you are missing many good opportunities.
Why Being Right Seems So Important
There are two primary reasons why we focus on being right. First, we
are conditioned to be right by the school system. Second, everyone
in the trading industry gives people what they want—ways to be
right—which tends to perpetuate the myth. Let’s take a closer look
at these two reasons.
First, we are
conditioned by the school system to the importance of being right.
In school you are taught that there are right answers and wrong
answers. What is a right answer? If you learned how to survive in
the system, you learned that a "right" answer is whatever the
teacher wanted.
Your performance is
measured periodically through tests in which you are asked to pick
the right answer. If you cannot get more than 70% right on the test,
you are labeled a failure and ostracized. Your humiliation might
even be in public in front on all your friends. And if your
humiliation isn’t public, it certainly is semipublic. Your "poor"
performance goes home in the form of a grade with a comment that
"Johnny is a little slow or Johnny is bright, but he just doesn’t
try." Usually, at this point, the most important people in your
young life get involved—your parents.
Even if you understand
the system and work hard to know the right answers, you still might
be taught that your performance is not good enough. It usually takes
94% right to get an excellent grade. But how many children go home
and show their 94% test to dad only to get the response, "Why didn’t
you get 100%?"
Thus, it is no wonder
that traders want to be right all the time. And being right usually
costs them dearly in terms of profits. Whether you’ve been through
20 years of schooling and have a graduate degree or less than 10
years of schooling, you still have the same conditioning about being
right.
The second reason
people want to be right is that service providers for traders and
investors feed the bias to be right. First, software vendors tend to
provide systems that can be highly optimized. Once you’ve optimized
your trading, you can lay a line over the prices and see exactly
where you should have bought and sold. It seems obvious. However,
the same optimized system does very poorly when applied to the real
world.
The Solution: Expectancy
What you must do now that you are trying to survive in the real
world is learn about expectancy. My book, Trade Your Way to
Financial Freedom is one of the best sources I know that covers
this topic. By definition expectancy is how much you can expect to
make, on the average, over many trades. Expectancy is best stated in
terms of how much you can make per dollar that you risk. I cover
this important topic as well as detailed instructions on how to
calculate expectancy. My objective is to show you how to incorporate
expectancy into a successful, profit generating trading system.
