Before becoming one of the most successful macro traders in history, Bruce Kovner borrowed against a credit card to fund an early futures trade — soybeans, if the well-known account is accurate — and put on a position with real conviction.
The pain: He didn't set a protective stop-loss. Overnight, the market moved sharply against him, and by the time he could react, the position had lost a large share of the capital he'd borrowed to fund it. It was a gut-punch early lesson delivered in the most expensive way possible.
The lesson: Kovner rebuilt his entire trading philosophy around that single near-disaster: know your exit before you know your entry. He described deciding his stop-loss level as the very first step of any trade — before position size, before target, before conviction — because a trade without a predetermined exit isn't really a trade, it's a hope. He built a career trading large, diversified macro positions across currencies, rates, and commodities, but every single one carried a defined risk decided in advance, sized so that no single position could meaningfully damage the whole portfolio.
His rule is uncomfortable precisely because it's so simple: if you can't say exactly where you're wrong before you enter, you haven't finished planning the trade yet.
Key Takeaway
One forgotten stop-loss, early and expensive, became the foundation of a legendary career. Decide where you're wrong before you decide where you might be right.
Think About It
Have you ever entered a trade "quickly" and told yourself you'd set the stop-loss in a minute? What actually happened the last time you did that?
