1 The Story
From taxi driver to macro legend
Bruce Kovner (born 1945) was a self-taught trader — once a taxi driver — who built Caxton Associates into one of the most successful global-macro funds, running it from 1983 to 2011, and was profiled in Market Wizards.1
His hallmark is risk management through restraint: knowing his exit before entering, sizing to survive being wrong, and advising traders to 'undertrade' rather than over-bet.1
2 The Big Idea
Survival is the strategy
Decide where you're wrong before you enter — then bet small enough to survive it.
Kovner's edge wasn't being right more often; it was never letting a wrong call ruin him. He fixed his exit in advance, sized positions so a loss was survivable, and deliberately under-traded. Defense first, offense second.1
3 The Method
Disciplined macro
Know your exit first
Never enter without a predetermined stop. The exit, not the entry, is decided before the trade.
Size to survive
Bet small enough that being wrong costs little — so you're always around for the next opportunity.
Undertrade
When in doubt, do less. Restraint is the macro trader's edge over a market full of over-bettors.
4 Try It Today
Test the idea for yourself
A no-risk exercise
Before your next paper trade, write down — in advance — exactly where you'd admit you're wrong and exit, and how small the position must be for that loss to barely dent the account. That single habit is Kovner's whole edge.
