Of course, when I found that morning a market in which I could sell out all my stocks without any trouble I did so. When you are selling out it is no wiser or braver to sell fifty shares than fifty thousand; but fifty shares you can sell in the dullest market without breaking the price and fifty thousand shares of a single stock is a different proposition. I had seventy-two thousand shares of U.S. Steel. This may not seem a colossal line, but you can’t always sell that much without losing some of that profit that looks so nice on paper when you figure it out and that hurts as much to lose as if you actually had it safe in the bank.

I had a total profit of about $1,500,000 and I grabbed it while the grabbing was good. But that wasn’t the principal reason for thinking that I did the right thing in selling out when I did. The market proved it for me and that was indeed a source of satisfaction for me. It was this way: I succeeded in selling my entire line of seventy-two thousand shares of U.S. Steel at a price which averaged me just one point from the top of the day and of the movement. It proved that I was right, to the minute. But when, on the very same hour of the very same day I came to sell my 5000 shares of Utah Copper, the price broke five points. Please recall that I began buying both stocks at the same time and that I acted wisely in increasing my line of U.S. Steel from twenty thousand shares to seventy-two thousand, and equally wisely in not increasing my line of Utah from the original 5000 shares. The reason why I didn’t sell out my Utah Copper before was that I was bullish on the copper trade and it was a bull market in stocks and I didn’t think that Utah would hurt me much even if I didn’t make a killing in it. But as for hunches, there weren’t any.

The training of a stock trader is like a medical education. The physician has to spend long years learning anatomy, physiology, materia medica and collateral subjects by the dozen. He learns the theory and then proceeds to devote his life to the practice. He observes and classifies all sorts of pathological phenomena. He learns to diagnose. If his diagnosis is correct—and that depends upon the accuracy of his observation—he ought to do pretty well in his prognosis, always keeping in mind, of course, that human fallibility and the utterly unforeseen will keep him from scoring 100 per cent of bull’s-eyes. And then, as he gains in experience, he learns not only to do the right thing but to do it instantly, so that many people will think he does it instinctively. It really isn’t automatism. It is that he has diagnosed the case according to his observations of such cases during a period of many years; and, naturally, after he has diagnosed it, he can only treat it in the way that experience has taught him is the proper treatment. You can transmit knowledge—that is, your particular collection of card-indexed facts—but not your experience. A man may know what to do and lose money—if he doesn’t do it quickly enough.

Observation, experience, memory and mathematics—these are what the successful trader must depend on. He must not only observe accurately but remember at all times what he has observed. He cannot bet on the unreasonable or on the unexpected, however strong his personal convictions may be about man’s unreasonableness or however certain he may feel that the unexpected happens very frequently. He must bet always on probabilities—that is, try to anticipate them. Years of practice at the game, of constant study, of always remembering, enable the trader to act on the instant when the unexpected happens as well as when the expected comes to pass.

A man can have great mathematical ability and an unusual power of accurate observation and yet fail in speculation unless he also possesses the experience and the memory. And then, like the physician who keeps up with the advances of science, the wise trader never ceases to study general conditions, to keep track of developments everywhere that are likely to affect or influence the course of the various markets. After years at the game it becomes a habit to keep posted. He acts almost automatically. He requires the invaluable professional attitude and that enables him to beat the game—at times! This difference between the professional and the amateur or occasional trader cannot be overemphasised. I find, for instance, that memory and mathematics help me very much. Wall Street makes its money on a mathematical basis. I mean, it makes its money by dealing with facts and figures.

When I said that a trader has to keep posted to the minute and that he must take a purely professional attitude toward all markets and all developments, I merely meant to emphasise again that hunches and the mysterious ticker-sense haven’t so much to do with success. Of course, it often happens that an experienced trader acts so quickly that he hasn’t time to give all his reasons in advance—but nevertheless they are good and sufficient reasons, because they are based on facts collected by him in his years of working and thinking and seeing things from the angle of the professional, to whom everything that comes to his mill is grist. Let me illustrate what I mean by professional attitude.

I keep track of the commodities markets, always. It is a habit of years. As you know, the Government reports indicated a winter wheat crop about the same as last year and a bigger spring wheat crop than in 1921. The condition was much better and we probably would have an earlier harvest than usual. When I got the figures of condition and I saw what we might expect in the way of yield—mathematics—I also thought at once of the coal miner’s strike and the railroad shopmen’s strike. I couldn’t help thinking of them because my mind always thinks of all developments that have a bearing on the markets. It instantly struck me that the strike which had already affected the movement of freight everywhere must affect wheat prices adversely. I figured this way: There was bound to be considerable delay in moving winter wheat to market by reason of the strike-crippled transportation facilities, and by the time those improved the spring wheat crop would be ready to move. That meant that when the railroads were able to move wheat in quantity they would be bringing in both crops together—the delayed winter and the early spring wheat—and that would mean a vast quantity of wheat pouring into the market at one fell swoop. Such being the facts of the case—the obvious probabilities—the traders, who would know and figure as I did, would not bull wheat for a while. They would not feel like buying it unless the price declined to such figures as made the purchase of wheat a good investment. With no buying power in the market, the price ought to go down. Thinking the way I did I must find whether I was right or not. As old Pat Hearne used to remark, “You can’t tell till you bet.” Between being bearish and selling there is no need to waste time.

Experience has taught me that the way a market behaves is an excellent guide for an operator to follow. It is like taking a patient’s temperature and pulse or noting the colour of the eyeballs and the coating of the tongue.

Now, ordinarily a man ought to be able to buy or sell a million bushels of wheat within a range of ¼ cent. On this day when I sold the 250,000 bushels to test the market for timeliness, the price went down ¼ cent. Then, since the reaction did not definitely tell me all I wished to know, I sold another quarter of a million bushels. I noticed that it was taken in driblets; that is, the buying was in lots of 10,000 or 15,000 bushels instead of being taken in two or three transactions which would have been the normal way. In addition to the homeopathic buying the price went down 1¼ cents on my selling. Now, I need not waste my time pointing out that the way in which the market took my wheat and the disproportionate decline on my selling told me that there was no buying power there. Such being the case, what was the only thing to do? Of course, to sell a lot more. Following the dictates of experience may possibly fool you, now and then. But not following them invariably makes an ass of you. So I sold 2,000,000 bushels and the price went down some more. A few days later the market’s behaviour practically compelled me to sell an additional 2,000,000 bushels and the price declined further still; a few days later wheat started to break badly and slumped off 6 cents a bushel. And it didn’t stop there. It has been going down, with short-lived rallies.

Now, I didn’t follow a hunch. Nobody gave me a tip. It was my habitual or professional mental attitude toward the commodities markets that gave me the profit and that attitude came from my years at this business. I study because my business is to trade. The moment the tape told me that I was on the right track my business duty was to increase my line. I did. That is all there is to it.
