In "Psychology of the Stock Market," G. C. Selden argues that erratic market fluctuations are primarily driven by the psychological conditions of traders rather than manipulation or simple factual data. The author identifies two distinct classes of minds reflected in market prices: the "impulsive" operator and the "phlegmatic" investor. The impulsive operator buys at the top and sells at the bottom based on immediate conclusions, willing to purchase stocks if prospects for further advance exist. Conversely, the phlegmatic investor rarely buys on advances, reasoning that prices often move against fundamental conditions. Instead, this type places scale orders to buy on declines and sell on advances, a strategy common among large capitalists and bankers who lack the time to watch the ticker closely but possess the capital to absorb small fluctuations. These opposing forces create market reactions, support, and pressure. When banking interests believe conditions are sound, they place scale orders to buy on declines. Active floor traders may initially drive prices down, but the market must decline until this floating supply is absorbed by standing orders, creating a "reaction." Once absorbed, the market rises to a new high. Eventually, profit-taking sales meet scale orders at various prices, increasing the floating supply until another reaction occurs. This process leads to periods of "distribution" at market tops and "accumulation" at bottoms. Selden emphasizes that the common assumption that support or pressure is supplied by manipulators is often incorrect; it frequently results from the scale operations of hundreds of individuals whose mental makeup prevents impulsive trading. Selden further addresses the necessary mental attitude for success. He warns that erratic fluctuations result from traders operating on what they believe others will do, rather than on facts alone. While basing operations on public sentiment is not inherently wrong, it requires experience. The intelligent investor should focus on facts and prices, guarding against confusion by public sentiment or inverted reasoning. Active traders must be "reasoning optimists," believing they can float with the tide rather than trying to move it. Enthusiasm, fear, anger, and depression cloud the intellect and must be avoided. The author cautions against stubbornness, distinguishing between persistence and adhering to a course of action that events have proven erroneous. A common error is "getting a notion," where a trader focuses on a single factor while ignoring broader conditions. Successful traders learn to study their own psychological characteristics, allowing for customary errors of judgment by waiting, reflecting, and holding reserve commitments. Ultimately, the book serves as a guide for avoiding unwise risks by applying sound analysis and understanding the human element that drives financial markets.
