1 The Story
Defense wins
Paul Tudor Jones II (born 1954) is an American hedge fund manager who founded Tudor Investment Corporation in 1980 and earned fame by anticipating and profiting from the 1987 stock-market crash.1
A discretionary global-macro trader, he is known above all for defense — capital preservation, asymmetric risk/reward, and cutting losers fast.1
2 The Big Idea
Protect capital; take asymmetric bets
Don't focus on making money — focus on protecting what you have.
Tudor Jones's edge is risk-first thinking: preserve capital above all, and only take trades where the potential reward dwarfs the risk. Get those asymmetric bets right a fraction of the time and the math still works — provided you cut the losers fast.1
3 The Method
Risk-first macro
Capital preservation first
The priority isn't the next win — it's not blowing up. Defense is the foundation of offense.
Asymmetric risk/reward
Seek trades where the upside is several times the downside; you don't need to be right often to win.
Cut losers fast
'Losers average losers' — never add to a losing position; admit the mistake and move on.
4 Try It Today
Test the idea for yourself
A no-risk exercise
Before any trade, write the potential loss and the realistic potential gain, and form the ratio. Tudor Jones would pass unless the reward clearly dwarfs the risk. Practising that filter — and walking away when it fails — is most of his discipline.
