The Thesis
Livermore read the tape and market psychology perfectly, recognizing the speculative mania of the late 1920s was unsustainable and positioned short before the historic crash.
The Story
Jesse Livermore, the legendary "Boy Plunger" of Wall Street, made his most famous trade in October 1929. While the entire nation was caught up in speculative euphoria and buying stocks on margin, Livermore was quietly building a massive short position. His decades of experience reading market action — the way stocks behaved, volume patterns, and the psychology of crowds — told him the market was dangerously overextended. He had been bankrupted before and rebuilt his fortune multiple times, giving him a rare perspective on market cycles.
When the market crashed on Black Tuesday, October 29, 1929, Livermore reportedly earned approximately $100 million — equivalent to several billion dollars today. It was one of the few bright spots in an event that devastated millions. Livermore's success came from his deep understanding of market psychology and price action, principles he later outlined in "Reminerta in Stocks," ghostwritten by Edwin Lefevre, which remains one of the most influential trading books ever written nearly a century later.
Key Insight
Markets are driven by human emotions — fear and greed — and those who study psychology have an edge over those who only study fundamentals.
“There is nothing new in Wall Street. There can't be because speculation is as old as the hills.”
