The stock market literature of the past thirty years would make a vast library in itself--one that would provide reading for a lifetime. Perhaps there is no other subject, apart from the eternal topic of love, in which more people are vitally concerned, either directly or indirectly. Since most of the country’s wealth and commerce is controlled by corporations whose securities are listed on the various stock exchanges, the price fluctuations, which often reach the daily aggregate of hundreds of millions of dollars, either in loss or enhancement of value, are necessarily a matter of general concern. In 1925 the stock transactions on the New York Stock Exchange alone amounted to the stupendous and unprecedented total of well over 452,000,000 shares, while the sales of listed bonds totaled more than $3,398,000,000. These figures, of course, do not include the unknown billions of dollars worth of securities bought and sold on a dozen or more other exchanges and through private channels.
In addition to the large daily grist of “Market Opinions,” many books and pamphlets are written which purport to be “Guides to Traders,” or up-to-date recipes for “Beating Wall Street.” They set forth an exhaustive array of statistics, instructions and warnings; they furnish elaborately charted plans indicating many of the pitfalls of speculation; they tell how to avoid these, how to buy, what to buy, when to buy and how to make money; but while the theories advanced are oftentimes sound and easily comprehended, very few people profit by them, because when once caught in the maelstrom of stock speculation the average man becomes more or less mesmerized, and at critical moments his conservatism, his resolutions and his theories all take flight. Under the discomposing influence of a rapid succession of changing values and alternating impulses he loses his perspective, is incapable of calm reasoning, and is likely to do precisely the opposite of what he had intended doing. Like a piece of driftwood in a swirling stream, his actions are controlled less by personal instigation than by the currents about him. Therefore to write, however intelligently, or to read, however studiously, about how to make money in the stock market is largely wasted effort in imparting, also in acquiring, information that does not adequately inform. Not that the instructor’s premises are faulty, or that the reader is deficient in understanding; but that the difficulties which necessarily attend the application of the scheme of operations subsisting in the mind of the author are so perplexing and disconcerting that the disciple becomes incapable of adhering to sound basic principles. And it must be perfectly obvious to anyone that even the teacher himself is not a master, but merely an expounder, of his own principles; for otherwise he would be a capitalist instead of a professional scribbler. Notwithstanding the many excellent books which have been written on the subject, the real secret of stock market success still remains (and probably always will remain) locked up in the bosoms of a few who are too busy to write, and too rich to feel the need of writing.
