Trading Axioms

A
self-evident truth is a logical statement used in a series of statements to formulate a philosophy or scientific hypothesis. The statements listed on this page define the fundamental principles from which all the trading strategies and techniques on this site are derived.

  1. THE PRICE MOVEMENT OF A STOCK IS DETERMINED BY SUPPLY-AND-DEMAND. WHEN PUBLIC DEMAND IS GREATER THAN THE SUPPLY, ITS PRICE WILL RISE. WHEN THE SUPPLY IS GREATER THAN THE DEMAND THE PRICE WILL FALL.
  2. A stock's "supply" is simply number of shares that are up for sale at given price, while "demand" is the number of shares willing to be purchased at a given price. If demand increases, the buyer is willing to pay more than the current market value; if demand decreases the seller is willing to sell for less than the current market value. These are the lone forces that cause a stock's price to rise and fall.

  3. THE DEMAND (OR LACK OF DEMAND) FOR A STOCK IS CREATED BY SPECULATION OF THE STOCK'S FUTURE VALUE.
  4. Stock is always purchased with the anticipation that it will rise in value. Stock is always sold with the anticipation that it will fall in value or at least no longer rise. A high demand for stock is created from a widely held belief that it will be worth more in the future.

  5. SPECULATION, BY DEFINITION, MUST CONTAIN THE CONCEPT OF A FUTURE. THE DEMAND (OR LACK OF DEMAND) FOR A STOCK IS ALWAYS THE RESULT OF SPECULATORS GUESSING ITS FUTURE (AND NOT ITS PRESENT) VALUE.
  6. Speculation is always about the future, not the past or present. If there is no belief that a stock's value will increase in the future there is no incentive to hold the stock.

  7. REMOVING FUTURE PROSPECTS REMOVES THE SPECULATIVE ELEMENT OF A STOCK.
  8. There's an old saying on Wall Street, "Buy on the rumor, sell on the news." Very often, a stock will rise on rumors of high earnings and other growth prospects. Once the rumor materializes the stock gets sold off, falling in price. To understand why this occurs, consider the fact that stock prices are determined by speculation of future value, so once a rumor becomes fact, the element of future has been eliminated.

  9. AN INCREASE IN DEMAND FOR A STOCK, DETERMINED BY SPECULATION OF FUTURE VALUE, WILL CAUSE, BY ITSELF, THE RISE IN PRICE THAT IS ANTICIPATED. A STOCK PRICE MOVEMENT IS THEREFORE, BY DEFINITION, A SELF-FULFILLING PROPHECY.
  10. This phenomenon has always fascinated me. Consider an investor who buys into a company because he thinks its stock will rise in value. Others, just like himself, buy into the stock for the same reasons. The result is an increase in demand, hence an increase in price, the very thing they were anticipating. Note that the speculative investor, and not the company's fundamentals, drove up the value of the stock!

  11. MARKET VALUE OF A STOCK IS SOLELY DETERMINED BY WHAT A SPECULATOR IS WILLING TO PAY; IN REALITY THERE IS NO OTHER EVALUATION MECHANISM THAT DETERMINES PRICE.
  12. What is a stock's true value? It is the price someone is willing to pay for it, period. One might have various theories about its "fair value" and you will hear endless commentaries on stocks that are "undervalued" and "overvalued." Yet no one will ever get around the fact that the stock is worth what someone will pay for it, today, regardless of opinion.

  13. SUCH THINGS AS "COMPANY FUNDAMENTALS" ARE ONLY IMPORTANT IF AND WHEN SPECULATORS THINK THEY ARE IMPORTANT. THE STRENGTH (OR WEAKNESS) OF THE UNDERLYING COMPANY WILL INFLUENCE A STOCK ONLY TO THE EXTENT THAT SPECULATORS ASSIGN VALUE TO SUCH THINGS.
  14. Investors often lose sight of the fact that price movements are determined their own collective speculation, not by the underlying company. Company fundamentals may be outstanding, yet if speculators don't think so then the stock's value will not reflect any of these fundamentals. In reverse, company fundamentals may be unsound, yet speculators may like stock for whatever reason and bid it up. Investing into fundamentals is only successful when and if the speculators believe the fundamentals are worth speculating about.

  15. INCREASING, COLLECTIVE SPECULATION CREATES PRICE MOMENTUM. IT CAN BE NEGATIVE OR POSITIVE.
  16. A single speculator probably won't move the price of a stock, but the combined efforts of many will. Movement in either direction could be a study in the subject of "mob psychology." When speculators see what other speculators are doing, there is a tendency for a bandwagon effect, which we call price momentum.

  17. SUCCESSFUL TRADING CAN ONLY BE ACHIEVED BY ACCURATELY PREDICTING THE BEHAVIOUR OF SPECULATORS. IN A SENSE, ONE MUST SPECULATE ON THE SPECULATORS.
  18. The art of stock trading lies in the simple fact that the sentiment of speculators is the lone force that drives the market, not company fundamentals or any other factor. If speculators feel positive about a company's future then the stock will rise, not because the company's future is bright, but because the speculators think it is bright.

  19. ALL SUCCESSFUL TRADES OCCUR BECAUSE THE TRADER CORRECTLY PREDICTED THE DIRECTION OF PRICE MOMENTUM. IT IS THEREFORE THE STUDY OF THE SPECULATOR, AND NOT THE UNDERLYING COMPANY THAT LEADS TO SUCCESS.

The study of company fundamentals is futile without considering the interpretation of speculators. In many cases, the speculators in turn are influenced by "expert" analysis and interpretation of the facts. In either case, the success or failure of trading can be traced directly to the success or failure of predicting the direction of the composite of all speculation.
