First published in New York in 1912, Psychology of the Stock Market is a compact classic that treats the market as a living arena of human impulses: hope, fear, imitation, stubbornness, and the contagious confidence that builds booms and the contagious dread that triggers panics. Selden’s central idea is simple and still startlingly modern: day to day price movements are driven to a very large degree by the mental attitudes of the investing and trading public.
Markets change, technology changes, and instruments change, but the human mind does not. Selden’s great contribution is showing how quickly intelligence can be overridden by crowd emotion, and how success often comes down to managing the psychology of decision making as much as analyzing fundamentals.
