Who Was Jesse Livermore? The Life and Trading Lessons of the Boy Plunger

Jesse Lauriston Livermore (1877–1940) is probably the most studied speculator in American history. He made and lost several fortunes, and he was famous for shorting the market before two of its worst collapses. A century later traders still read him. Not because his trades can be copied, but because he wrote down, more honestly than most, what goes on inside a trader's head.

This article covers his career and the handful of ideas that make up what people now call the "Livermore method."

From quotation boy to bucket-shop terror

Livermore left his family's Massachusetts farm as a teenager and found work chalking stock prices on the quotation board of a Boston brokerage. Watching prices all day, he started noting in a notebook how they behaved before they moved. He wasn't asking why a stock moved, only how it acted beforehand.

He put that notebook to work in the bucket shops: storefront betting parlours where customers wagered on price moves without any shares actually changing hands. He won so consistently that shops across New England banned him, and he earned the nickname "the Boy Plunger."

Lesson: his edge began as observation, not prediction. He wrote down what price did and acted only when the pattern he was watching for showed up.

Learning the hard way on Wall Street

When he moved to New York brokerages, the habits that worked in bucket shops failed him. Real orders filled at real prices, often well away from the last quote on the tape. He went broke more than once. Each time he rebuilt, and each time he took away a rule:

• Trading every small fluctuation is expensive. The big money is in the big moves.
• Being right about direction is worthless if your timing is wrong.
• Tips, even from insiders, are a way to lose money on someone else's opinion.

1907 and 1929

Livermore's two best-known trades were short sales into market panics. In the Panic of 1907 he made a fortune shorting into the collapse. By most accounts he was asked to stop pressing the market, and he did. In 1929 he was again heavily short going into the crash, and contemporary reports put his profit at around $100 million.

Both trades were years in the making. In each case he had watched leadership stocks fail to make new highs while the public stayed euphoric, and he built his short position in stages as the market confirmed him.

Lesson: the large wins came from patience and confirmation, not from guessing the top on a particular day.

Why he still matters

Livermore also went bankrupt several times, including after his 1929 triumph, and his life ended tragically in 1940. That part of the story matters too. His methods were sound and his discipline was not always. He said so himself: his worst losses came when he broke his own rules.

His thinking survives in two books:

1. Reminiscences of a Stock Operator (1923), Edwin Lefèvre's thinly fictionalised account of Livermore's career, told through the character "Larry Livingston."
2. How to Trade in Stocks (1940), Livermore's own short manual describing pivotal points and his record-keeping method.

The core principles in one list

• Trade with the line of least resistance. Buy in up-trends and sell short in down-trends. Don't fight the tape.
• Wait for the pivotal point. Enter when price confirms the move by breaking through a key level, not before.
• Probe, then pyramid. Start small and add only when the trade shows a profit.
• Cut losses fast. A small loss is the price of being wrong. A large one is the price of being stubborn.
• Sit tight. Once a trend is confirmed, the profit comes from staying in it.
• Ignore tips and the crowd. Price action is the only witness that never lies.

We cover each of these in detail in our methodology guide, and the psychology behind them in Hope, Fear and the Discipline of Cutting Losses.
