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.

Kovner's discipline: the exit is set before entry, and the position is sized so that being wrong is survivable.1

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.

5 In Their Words

Bruce Kovner, quoted

"Whenever I enter a position, I have a predetermined stop. That is the only way I can sleep."
