Overconfidence in trading is the downfall of many successful traders. Too much confidence makes you do irrational decisions and take too much risk. Not only are you more likely to overtrade, but you are more likely to unconsciously increase your risk-taking. Risk-taking involves the thin line between success, fiasco, and luck/unluck.
Is there a correlation between good trading and intelligence?
This morning I had a look in one of the old Market Wizards books by Schwager. William Eckhardt on page 127 and 128 said the following:
I haven’t seen much correlation between good trading and intelligence….Many outstandingly intelligent people are horrible traders….Avearge intelligence is enough. Beyond that, emotional makeup is more important. …Anyone with average intelligence can learn to trade. This is not rocket science.
I totally agree with Eckhardt. Why should intelligence be so important for good trading? Intelligence is overrated. Discipline, patience, knowledge, attention to detail and some creativity are much more important than intelligence. I have taken an IQ test twice (in English, which might underestimate my score). I scored just BELOW average both times. Still, I have performed quite well in trading: 12 years of day trading and just two losing months (both in 2012). Obviously, I don’t consider myself stupid, but my intelligence is at best average. I believe I have other characters that make up for my lack of intelligence.
Why is overconfidence a bad thing?
If you’re intelligent you might become very confident. True, confidence is important, but overconfidence is lethal to your account. Coupled with a big ego that is a sure way to the financial risk of ruin in the markets.
After his 1929 blowout Livermore, overflowing with confidence, made larger and larger bets. He wound up far over his head, in increasing amounts of debt, and eventually lost everything in the stock market……Livermore eventually took his own life.
If you have no fear of failure, you will fail. Of course, fear of failure can’t paralyze you, but no fear of failure is just as bad.
I believe overconfidence is a very bad trait in trading. It will make you blind to risk and make you feel better than you are. Luck and randomness are much bigger factors than most realize. You have to be humble. The inevitable result is that you take on more risk than you should. You have to know that failure is a possibility. If not you get complacent and inefficient.
If I were to employ someone in my one-man firm (actually, I just made an agreement with someone this month) I would boil down my criteria to these things: determination, motivation, persistence, modesty/frugality, and discipline (work ethics). The rest can be taught.
How do you stop overconfidence?
There are two important steps in overcoming overconfidence:
Trading is all about survival:
First and foremost always keep in the back of your head that trading is about survival. Getting rich requires taking risks, but you need to survive to exploit the edges that the market throws at you. There is no point in spending time finding trading edges if your account doesn’t survive.
Be slow and steady:
Don’t rush decisions: make sure you have thought things over. Daniel Kahneman wrote in his best-selling book, Thinking Fast, And Slow, about two systems in making decisions: System 1 which is the intuitive and gut feel, while System 2 is the slow, rational, and analytical mindset.
Trading should mostly be about system 2.
Trading is about persistence and survival:
The US president Calvin Coolidge nailed it*:
Nothing in this world can take the place of persistence. Talent will not; nothing is more common than unsuccessful people with talent. Genius will not; unrewarded genius is almost a proverb. Education will not; the world is full of educated failures. Persistence and determination alone are omnipotent.
The above is one of my favorite proverbs!
Calvin Coolidge has some insights to potential traders:
Many traders should listen to what Calvin Coolidge has to say:
- There is no dignity quite so impressive, and no one independence quite so important, as living within your means.
- You can’t know too much, but you can say too much.
- All growth depends upon activity. There is no development physically or intellectually without effort, and effort means work.
- Civilization and profit go hand in hand.
- Duty is not collective, it is personal.
- Four-fifths of all our troubles would disappear if we would only sit down and keep still.
- If I had permitted my failures, or what seemed to me at the time a lack of success, to discourage me I cannot see any way in which I would ever have made progress.
- Industry, thrift, and self-control are not sought because they create wealth, but because they create a character.
- Don’t expect to build up the weak by pulling down the strong.
- It takes a great man to be a good listener.
- No enterprise can exist for itself alone. It ministers to some great need, it performs some great service, not for itself, but for others; or failing therein, it ceases to be profitable and ceases to exist.
- No man ever listened himself out of a job.
