I can immediately hear an objection—what do you mean, go home without a loss? It is impossible to make money every day. What happens if you buy something, and it goes straight down—in other words, you’ve bought the top tick of the day? What if you sell something short and it immediately rallies?
We must draw a clear line between a loss and a businessman’s risk. A businessman’s risk is a small dip in equity. A loss goes through that limit. As a trader, I am in the business of trading and must take normal business risks, but I cannot afford losses.
Imagine you’re not trading but running a fruit and vegetable stand. You take a risk each time you buy a crate of tomatoes. If your customers do not buy them, that crate will rot on you. That’s a normal business risk—you expect to sell most of your inventory, but some fruit and vegetables will spoil. As long as you buy carefully, keeping the unsold spoiled fruit to a small percentage of your daily volume, your business stays profitable.
Imagine that a wholesaler brings a tractor-trailer full of exotic fruit to your stand and tries to sell you the entire load. He says that you can earn more in the next two days than you made in the previous six months. It sounds great—but what if your customers don’t buy that exotic fruit? A rotting tractor-trailer load can hurt your business and endanger its survival. It’s no longer a businessman’s risk—it’s a loss. Money management rules draw a straight line between a businessman’s risk and a loss, as you will see later in this blog.
Some traders have argued that my AA approach is too negative. A young woman in Singapore told me she believed in positive thinking and thought of herself as a winner. She could afford to be positive because discipline was imposed on her from the outside, by the manager of the bank for which she traded. Another winner who argued with me was a lady from Texas in her seventies, a wildly successful trader of stock index futures. She was very religious and viewed herself as a steward of money. Each morning she got up early and prayed long and hard. Then she drove to the office and traded the living daylights out of the S&P. The minute a trade went against her, she’d cut and run—because the money belonged to the Lord and wasn’t hers to lose. She kept her losses small and accumulated profits.
I thought that our approaches had a lot in common. Both of us had principles outside the market preventing us from losing money. Markets are the most permissive places in the world. You may do any- thing you like, as long as you have enough equity to put on a trade. It’s easy to get caught in the excitement, which is why you need rules. I rely on the principles of AA, another trader relies on her religious feelings, and you may choose something else. Just make sure you have a set of principles that clearly tells you what you may or may not do in the markets.
