The Psychology of Speculation: The Human Element in Stock Market Transactions

The year is 1926. The Roaring Twenties are in full swing, and the stock market is climbing toward an apex that most believe will never end. Into this atmosphere of unchecked optimism steps Henry Howard Harper with a quietly terrifying premise: the market isn't driven by logic, fundamentals, or even money. It's driven by people. And people, as Harper demonstrates with devastating precision, are their own worst enemies. This is not a book about charts, ratios, or insider tips. It's about what happens inside your skull when real money is on the line. Harper dissects the psychological forces that wreck traders: the hysteria that seizes a crowd, the overconfidence that follows a lucky win, the paralyzing fear that makes you sell at the bottom after holding through the crash. He shows how a man can enter a trading floor with a reasoned plan and emerge having done the exact opposite of what he intended. Written with the benefit of observing the market's cycles and human nature's constancy, Harper's analysis reads as prophecy when we know what followed in 1929. This is a slim, bracing manual for anyone who trades, invests, or wants to understand why crowds so reliably destroy themselves.
