      Trend Following Principles

      Trend Following

      An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

– Newton’s First Law of Motion

      Speculation is dealing with the uncertain conditions of the unknown future. Every human action is a speculation in that it is embedded in the flux of time.

– Ludwig von Mises19

      Speculation

      It might sound pedantic or perhaps that I am focusing on the extraneous, I am not: A speculator’s ability to receive a price they can count on as fact– is the foundation of markets. Said another way, with no price, humanity is back to cavemen beating each other with clubs. Austrian economist Ludwig von Mises puts price discovery’s value in perspective:

      It is the very essence of prices that they are the offshoot of the actions of individuals and groups of individuals acting on their own behalf. The catallactic concept of exchange ratios and prices precludes anything that is the effect of actions of a central authority, of people resorting to violence and threats in the name of society or the state or of an armed pressure group. In declaring that it is not the business of the government to determine prices, we do not step beyond the borders of logical thinking. A government can no more determine prices than a goose can lay hen’s eggs.20

      Although government can’t determine prices in the long run, in the short-term, government will attempt to directly rig the market system via QE, ZIRP, NIRP, or whatever acronym sure to follow.

      However, speculation is all there is for making choices about those market prices. Learning how best to speculate using prices is not only a worthy endeavor – it is a survival-of-the-fittest concept that traces back to the earliest literature of Wall Street.

      From Young America on Wall Street (1857), quoting a French poem about a latter-day millionaire:

      Monday, I started my land operations;

      Tuesday, owed millions, by all calculations;

      Wednesday, my brown-stone palace began;

      Thursday, I drove out a spanking new span;

      Friday, I gave a magnificent ball;

      Saturday, smashed – with just nothing at all.21

      There is nothing wrong with that turn of events. It’s normal. It’s the expected up and down. Luck is always in play, but so is skill. From The Theory of Stock Exchange Theory (1874):

      A man who wins by haphazard speculation, who chances to operate successfully until he has filled his pockets, and retires with his gains from so fascinating an arena, is one in a hundred. Any one who knows anything of Stock Exchange speculation will confirm the statement that, to the ordinary run of men, the game is not worth the candle. There are, however, conditions under which speculation, in a market where ten or fifty thousand pounds can be lost in half an hour, may, under given conditions, be systematically practiced profitably. First, and most important perhaps of all those conditions, is the temperament of the speculator. When it is known in a market that a great speculator is selling, weak bulls are speedily frightened out, and when he has such an object in view it is his game to intimidate with all the force of his prestige and the power of his capital. Such a man must have a concrete hardness of indifference through which nothing can penetrate to his heart. It is as necessary to the success of his operations that he posses no more regard for the feelings or pockets of other people than a hungry tiger would for him if he were airing himself unconcernedly in a Bengal jungle. He has a purpose in view, just as a surgeon has when the amputation of a leg has been decided upon. The speculator’s sole aim in the operation is the profit, towards which he cuts his way, regardless of the nature of the obstacles to be overcome, just as the knife is plunged into the flesh, severing the arteries, muscles, and sinews that surround the bone, which it is the object to reach and saw through. For a man to tread a path in which he must systematically not only disregard the interest of other people, but deliberately calculate upon the weaknesses of human nature which characterize the crowd, in order to work upon them for his own ends, it is obvious that he must be constituted in a quite exceptional manner, and not in a way that it is at all desirable others should attempt to imitate. If uninitiated people who enter the arena in which some of the professional speculators flourish, were to spend some months in gathering information and in close observance of the modus operandi, so far as they can get to see and hear, many of them would soon be persuaded that they were utterly useless at such work, and would retire, thanking their stars. The haphazard man, who is the antithesis of the professional speculator, will generally be found as differently constituted as are the results of his operations. The man who makes a study and business of speculating, investigating every detail that it seems necessary to probe until he has adapted it to the rest of his machinery, will be found to be a hard-grained man, sailing very close to the wind, while your persistently haphazard man is mostly a person of flabby character, and no less flabby mind, as easily frightened off a line that he has set himself to follow, in the innocence of a heart that expands with a delusive consciousness of possessing power, as a stray rabbit. Such a class of man is to be found by hundreds in the haunts of the stock markets, and they are always fidgeting in and out, first as little bulls, and then as little bears, disappearing after a sharp panic like flies from a joint of meat that is rudely disturbed by the shop-boy, with the important difference that whereas the flies always get something, the speculators invariably drop their money.22

      From How to Win and How to Lose (1883) arguably the first trend-based market player arrives: “The shrewdest operator ever known on the London Stock Board was David Ricardo (1772–1823) who amassed an enormous fortune. In advice to a friend he sums up as the true secret of his success, the rule, every word of which is golden. ‘Keep down your losses – never let them get away from you. Let your profits take care of themselves.’”23

      That precept is huge. Timeless. If you were to put Ricardo into language of modern day computer science 134 years later you would say, optimal stopping or win-stay, lose-shift or A/B testing. More clarification from 1883 keeps the focus on taking a loss: “Speculation is looked upon as being so much more risky than other avocations cause its results are more sudden and startling, though not one whit more disastrous. Statistics show that ninety-five out of one hundred men fail in mercantile life. The proportion is not greater among speculators: quicker action is obtained whether it be favorable or unfavorable, and it does not take five or ten years’ time to find that you are playing a losing game.”24

      No one is saying that attitude comes naturally. From The Art of Investing (1888): “Then, in theory, it is so easy to win by speculation! To buy at a low figure and sell at a higher, or to sell at a high figure and afterward buy at a lower, seems such a simple operation! It almost looks as if you could go into Wall Street and pick up money from the sidewalks.”25

      Intense study, practice, is the rock solid foundation. From Gold Bricks of Speculation (1904):
