Jesse Livermore’s three most useful trading lessons are to trade in the direction of the trend, to cut a losing trade quickly and keep the winners, and never to average down by buying more of something that is falling. He did not learn them from a book. He learned each one by losing a fortune, and then wrote down what it had cost him.
Livermore was an American speculator who lived from 1877 to 1940. Most of what traders know about him comes from Reminiscences of a Stock Operator, Edwin Lefèvre’s 1923 book, told in Livermore’s own voice. Every quote in this post comes from that book.
I first wrote about these three lessons in 2017. They have not changed, and if anything they have aged better than most of the trading advice written since.
Who was Jesse Livermore?
At 14, Livermore made his first trade, a profit of 3.12 dollars on a 5-dollar stake. By 21 he had arrived in New York with 2,500 dollars, and he was broke inside six months.
That pattern repeated for the rest of his career. In 1916, by his own account, “I cleared about three million dollars”. In 1908, he lost more than nine-tenths of his stake in a single cotton campaign. You will often read that he was worth 100 million dollars after shorting the 1929 crash. That figure comes from later biographies rather than from his own book, and I have not been able to check it against a primary source, so I would treat it as legend.
So why study someone who went broke more than once? Because he kept score of his mistakes better than almost anyone. As he put it, “All my life I have made mistakes, but in losing money I have gained experience and accumulated a lot of valuable don’ts.” Most of us make the same mistakes. We just never write them down.
What were Jesse Livermore’s three main trading rules?
Among the many lines in the book, three carry most of the weight for an ordinary trader, and they are the ones that, in my experience, decide whether an account survives its first few years.
| Lesson | What it means | What beginners do instead |
|---|---|---|
| 1. Trade with the trend | Buy what is rising, sell what is falling | Try to pick tops and bottoms |
| 2. Cut losses, keep winners | Close a losing trade quickly and hold the one that works | Hold the loser to “get back to even”, and sell the winner early |
| 3. Never average down | Do not buy more of a position that is going against you | Buy more to lower the average price |
Why trade with the trend instead of picking tops?
Many people love to pick tops and bottoms. It feels clever to call the turn before everyone else, and it makes for a great story at dinner when it works.
Livermore described the trend in terms that still hold up quite well. In his words, “prices, like everything else, move along the line of least resistance.” They go up when there is less resistance to an advance than to a decline, and down when the reverse is true. The level itself does not matter to him. He says plainly that “stocks are never too high to buy or too low to sell.”
That line is uncomfortable. Most of us learned to shop at a sale. A stock that has doubled feels expensive, so we look for one that has halved instead. But a stock that has halved usually halved for a reason, and the trend that pushed it down has no idea what you paid.
Do note that professional traders do occasionally trade against the trend. When they do, they use strict risk management and always have a plan for when the trade does not work out. Trend following is the simpler habit for most traders, because it is easy to add to a position as the move proves you right, and much less stressful than fighting the market every day. The trouble usually starts after a beginner makes some money with the trend, gets bored, and goes looking for new ways to trade. If you want to see how traders measure a trend, my guide to trend-following indicators covers the common ones.
Why is cutting a loss so hard?
Livermore’s rule on losses is about as short as a rule can get: “Always sell what shows you a loss and keep what shows you a profit.” He also said “A loss never bothers me after I take it. I forget it overnight.”
It is one thing to know that, and quite another to actually click the button when you are wrong. Cutting a loss is hard because of how most of us were raised. We are trained to be correct, and never to admit we messed up, because being wrong is supposed to reflect badly on us as people. With trading, no one is marking you for the number of losses. The profit you make is the final report card that matters.
That fear of being wrong is also why the losers get held. A small loss you take today feels like an admission. A small loss you hold still has hope in it, and hope is exactly what lets it grow.

What did averaging down cost Jesse Livermore?
In 1908, Livermore did the very thing he warned everyone else about, and the book tells the story in painful detail.
He had been bearish on cotton. Then a well-known cotton trader named Percy Thomas kept at him with facts and figures until he no longer felt sure of his own view. He covered his short, turned long against his own reading of the market, and when the cotton started losing money, he kept buying more instead of cutting it. As he admits, “And why do you think I bought it? To keep the price from going down! If that isn’t a supersucker play, what is?”
At the same time he was holding wheat, which was showing a nice profit. He sold the wheat and kept the cotton. He summed it up in one line: “The cotton showed me a loss and I kept it. The wheat showed me a profit and I sold it out.”
“I accumulated four hundred and forty thousand bales before I realised what I was doing. And then it was too late.” He lost more than nine-tenths of his stake. His verdict on the whole idea is the third lesson in his own words: “Of all speculative blunders there are few greater than trying to average a losing game.”
In my 2017 post, I quoted something I had heard from people more than once: “Even if the stock drops a lot, I’ll just keep it because I’m buying for ownership and dividend cashflow.” Fine. But what happens when it drops 70% or 80%, and do you keep buying more all the way down? Buying more when a stock has fallen is a sure way to take a trading account to zero, because you are taking more risk exactly when the odds have turned against you. My post on position sizing covers how to keep any single bet small enough that one mistake cannot sink the account.
Doesn’t buying lower mean getting more for less?
On 2 January 2025, a trader on Reddit’s r/Daytrading pushed back on Livermore’s habit of adding to winners. They wrote that “buying more as something goes lower makes sense because you’re getting more for less.”
That is a fair point. In one situation it holds up. Someone buying a broad index fund on a fixed plan did well to keep buying in early 2020. The S&P 500 fell 33.9% from its close on 19 February 2020 to 23 March 2020, and it was back at a record close by 18 August 2020. An index holds hundreds of companies, and it has a long record of recovering from falls like that one.
A single trade works differently. You bought it because you expected it to go up, and the price falling is the market telling you that expectation was wrong. Buying more at that point is a bet that the market is wrong instead. Livermore’s 440,000 bales were “more for less” right up until the end, and that is the part of averaging down that only shows up afterwards.
Why do we sell winners too early and hold losers too long?
In July 1985, two finance professors, Hersh Shefrin and Meir Statman, published a paper in the Journal of Finance. Its title could have been written about Livermore’s cotton: “The Disposition to Sell Winners Too Early and Ride Losers Too Long”. The habit now has a name, the disposition effect, and later studies of real brokerage accounts found the same pattern.
Their explanation leans on regret. Selling a loser makes the mistake real, and the regret arrives the moment you click the button. Selling a winner gives you the relief of a sure profit. So the brain quietly pushes us towards the trade that feels better today, which is the exact opposite of Livermore’s rule.
What I find interesting is the gap in time. Livermore described the habit, in his own trades, roughly 77 years before economists gave it a name. The mistake was there all along. Naming it did not make it go away, and that is why a written rule beats good intentions.
Which lesson matters most?
Livermore’s own answer might be patience. “It never was my thinking that made the big money for me. It always was my sitting.” Sitting tight with a winner is lesson 2 seen from the other side.
Many traders realise early in their careers that their accounts could have been profitable if not for a few silly mistakes. Avoiding those mistakes takes experience, maturity, the right knowledge and, honestly, proper mentoring. I was lucky to be mentored by veteran traders early in my career, and their advice, built on thousands of hours of market experience, shaped a lot of how I trade today.
Acknowledging your own mistakes is a continuous process, and a trading journal is the simplest way to keep the list of don’ts that Livermore kept in his head.
FAQ
Who was Jesse Livermore?
Jesse Livermore was an American speculator who lived from 1877 to 1940. His career is told in Edwin Lefèvre’s 1923 book Reminiscences of a Stock Operator, which is still one of the most widely read trading books.
What are Jesse Livermore’s main trading rules?
Three carry most of the weight: trade with the trend, cut losses while keeping the winners, and never average down. In his words, “Always sell what shows you a loss and keep what shows you a profit.”
What did Jesse Livermore say about averaging down?
“Of all speculative blunders there are few greater than trying to average a losing game.” He learned it in 1908, when he kept adding to a losing cotton position and lost more than nine-tenths of his stake.
Was Jesse Livermore really worth 100 million dollars?
That figure for 1929 comes from later biographies, and it does not appear in Reminiscences of a Stock Operator. The book itself records him clearing about three million dollars in 1916.
What is the line of least resistance?
It is Livermore’s name for the direction prices find easiest to travel. In his words, prices “move along the line of least resistance”. They rise when there is less resistance to an advance than to a decline, and fall when the reverse is true.
Is Reminiscences of a Stock Operator worth reading today?
Yes. The market details are a century old, but every rule in it comes attached to the trade that taught it, which makes the lessons much easier to remember.
So which of the three has cost you the most, trading against the trend, holding a loser, or buying more of it? Let me know in the comments.
