1. Have a Comprehensive Plan: Whether you are an investor or active trader, you must have a plan. Too many investors have no strategy at all — they merely react to each twitch of the market on the fly. If you fail to plan, goes the saying, then you plan to fail.
Consider how Roger Clemens approaches a game. He studies his opponent, constructs his game plan and goes to work.
Investors should write up a business plan, as if they were asking a Venture Capitalist for start-up money; just because you are the angel investor doesn’t mean you should skip the planning stages.
2. Expect to Be Wrong: We’ve discussed this previously, but it is such a key aspect of successful investing that it bears repeating. You will be wrong, you will be wrong often and, occasionally, you will be spectacularly wrong.
Michael Jordan has a fabulous perspective on the subject: “I’ve missed more than 9,000 shots in my career. I’ve lost almost 300 games. Twenty six times, I’ve been trusted to take the game-winning shot and missed. I’ve failed over and over and over again in my life. And that is why I succeed.”
Jordan was the greatest ball player of all time, and not only because of his superb physical skills: He understood the nature and importance of failure, and placed it appropriately within a larger framework of the game.
The best investors have no ego tied up in a trade. Those who refuse to recognize the simple truism of “being wrong often” end up giving away unacceptable amounts of capital. Stubborn pride and lack of risk management allow egotists to stay in stocks down 30%, 40% or 50% — or worse.
3. Predetermine Stops Before Opening Any Position: Sign a “prenuptial agreement” with every stock you participate in: When it hits some point you have determined before you purchased it, that’s it, you’re out, end of story. Once you have come to understand that you will be frequently wrong, it becomes much easier to use stop-losses and sell targets.
This is true regardless of your methodology: It may be below support or beneath a moving average, or perhaps you prefer a specific percentage amount. Some people use the prior month’s low. But whatever your stop-loss method is, stick to it religiously. Why? The prenup means you are making the exit decision before you are in a trade — while you are still neutral and objective.
4. Follow Discipline Religiously: The greatest rules in the world are worthless if you do not have the personal discipline to see them through. I can recall every single time I broke a trading rule of my own, and it invariably cost me money.
RealMoney’s Chartman, Gary B. Smith, slavishly follows his discipline, and he notes that every time some hedge fund — chock full of Nobel Laureates and Ivy League whiz kids — blows up, the mea culpa is the same: If only we hadn’t overrode the system.
In Jack Schwager’s seminal book Market Wizards, the single most important theme repeated by each of the wizards was the importance of discipline.
5. Keep Your Emotion In Check: Emotion is the enemy of investors, and that’s why you must have a methodology that relies on objective data points, and not gut instinct. The purpose of Rules 1, 2 and 3 is to eliminate the impact of the natural human response to stress — fear and panic — and to avoid the flip side of the coin — greed.
Remember, we, as a species, were never “hard-wired” for the capital markets. Our instinctive “fight or flight response” did not evolve to deal with crossing moving averages or CEOs resigning or restated earnings.
This evolutionary emotional baggage is why we want to sell at the bottom and chase stocks at the top. The money-making trade — buying when there’s blood in the streets, and selling when everyone else is clamoring to buy — goes against every instinct you have. It requires a detached objectivity simply not possible when trading on emotion.
6. Take Responsibility: Many folks believe “the game is fixed.” To them, I say: get over it. Stop whining and take the proper responsibility for your trades, your losses and yourself.
Your knowledge of the game-rigging gives you an edge. So use your hard-won knowledge to make money. (more…)
Similes and metaphors play an important role in both the internal thought-process of a day trader as well as in communication between two traders. To describe the emotional reactions coupled to the movement of a stock in likeness to a rollercoaster, or to compare averaging down in hopes of breaking even to digging one’s self out of a hole is to use simile to quickly illustrate a particular situation as clearly and succinctly as possible. Every trader uses these analogies, each having his own favorites, and they are used to add structure to an environment that often lacks useful tools for explaining particular occurrences. 
Once, there were two farmers who lived in the desert. Both desperately needed to acquire water so they could survive the desert and support their families. After working together to search the area, they concluded there was water somewhere in the area but they were not sure where. So, they set out to find a water well. They started digging in similar locations between their properties. After they both dug for several days, the second farmer finally struck water. As soon as this happened, the first farmer could see it from a distance and ran over to the second farmer. Seeing that he had stuck a huge water well, he asked the farmer, “You and I had the same tools for digging and have been digging in similar locations. How did you find water and I did not?”
