Paul Tudor Jones called the 1987 crash and turned $1.5 million into $300 million in his first fund. His approach blends macro trend-following with obsessive risk management. Here's what traders can learn from him.

Paul Tudor Jones is one of the greatest macro traders in history. He founded Tudor Investment Corp in 1980, and in October 1987 tripled his money shorting the stock market crash. His first fund turned $1.5 million into $300 million in its first three years. Over four decades his funds have never had a down year at the macro level.
He's known in popular culture partly because of the 1987 documentary Trader (which he later tried to suppress), but his real legacy is a methodology that prioritizes survival above all else.
Jones describes himself as primarily a trend follower. He looks for markets — stocks, commodities, currencies, bonds — that are in clear trends, and he rides them. His starting point is always the price action itself, not a fundamental thesis.
A key element of his trend identification is the use of moving averages. He has cited the 200-day moving average as one of his most important tools. His rule of thumb: if a market is below its 200-day MA, he has no interest in owning it. The MA tells him whether the trend is intact or broken.
He also uses historical price patterns extensively. In the months before the 1987 crash, he overlaid the 1987 chart on the 1929 chart — they matched almost perfectly. That pattern recognition informed his position.
Jones's most quoted rule is his reward-to-risk requirement: he will not enter a trade unless he can identify a reward-to-risk ratio of at least 5:1. If he risks $1, he needs to see a credible path to making $5.
This rule has profound implications:
Jones is emphatic: losers average losers. Adding to a losing position is one of the most dangerous things a trader can do. When a trade moves against you, the market is telling you that your thesis is wrong or your timing is off. Adding more capital in that moment amplifies the damage when you're finally forced out.
His approach to a losing trade is the opposite: he cuts it quickly, reassesses, and may re-enter from scratch at a better level if the original idea still holds. The key is that a re-entry is a new trade with a new risk definition — not an attempt to recover losses from the old trade.
Jones thinks in terms of environments and cycles. He wants to know: what kind of market am I in? Is capital flowing into risk assets or out of them? Are credit spreads expanding? Is volatility rising?
He uses a wide set of inputs — economic data, central bank policy, sentiment extremes, cross-market relationships — to build a view of the macro backdrop. His individual trades then express that macro view at specific technical entry points.
This is the fusion that makes Jones distinctive: the macro thesis tells him what to trade and in which direction; the technical analysis tells him when and where to enter and where to put his stop.
In October 1987 Jones was short US equities going into Black Monday. He had studied the 1929 analogue obsessively. He recognized that the market had become dangerously extended, portfolio insurance programs were creating a structural fragility, and the 200-day MA had been broken.
When the crash came — the Dow fell 22% in a single day — Tudor Investment Corp made 62% in the month of October 1987. The fund was up over 200% for the year.
Jones later said the experience reinforced his core conviction: the single most important thing in trading is protecting your capital. Not making money — protecting it. The offence takes care of itself if the defence is airtight.
