## Samenvatting
Riskeer nooit meer dan 1% van je totale kapitaal op één enkele trade. Deze legendarische regel beschermde PTJ tijdens de crash van 1987.

Paul Tudor Jones' 1% Regel is simpel: riskeer bij elke trade slechts 1% van je totale account. Als je €100.000 hebt, mag je slechts €1.000 verliezen op één positie. Dit dwingt strakke stop losses en juiste positiegrootte. Tijdens Black Monday 1987, terwijl anderen werden weggevaagd, was Jones short gepositioneerd en verdiende $100 miljoen omdat zijn risicobeheer hem in leven hield om van de crash te profiteren.

## Paul Tudor Jones: The Trader Who Made $100 Million on Black Monday
October 19, 1987—Black Monday. The stock market crashed 22% in a single day, the largest one-day percentage decline in history. Billions evaporated. Traders were wiped out. Firms went bankrupt. But Paul Tudor Jones walked into the chaos and walked out $100 million richer.

How? Rigorous risk management. Jones had recognized the market's vulnerability through technical analysis and was positioned short. But more importantly, his 1% rule meant he'd survived dozens of losing trades in the months before, preserving capital for the big opportunity. Other traders had already blown up their accounts chasing losses.

Jones later said: 'The most important rule of trading is to play great defense, not great offense.' His 1% rule wasn't about maximizing profits on any single trade—it was about ensuring he'd survive long enough to be present when the truly massive opportunities appeared. Risk management isn't glamorous, but it's what separates survivors from statistics.

## The Mathematics of Survival: Why 1% Is the Magic Number
Why exactly 1%? The math is compelling. If you risk 1% per trade and hit 10 consecutive losing trades (unlikely but possible), you've lost only 9.6% of your account. Your capital remains largely intact. You can recover with a few good trades.

Now consider risking 5% per trade. Ten losses drops your account by 40%. To recover, you need a 67% gain—much harder. At 10% risk per trade, ten losses leaves you with just 35% of your capital. You'd need a 186% gain just to break even. The math becomes nearly impossible.

This asymmetry is why professional traders are obsessive about risk. A 50% loss requires a 100% gain to recover. A 90% loss requires a 900% gain. The 1% rule ensures you never dig a hole so deep that climbing out becomes mathematically improbable. It's not about winning every trade—it's about ensuring losses remain small enough to survive.

## Position Sizing: The Formula That Protects Your Capital
The 1% rule translates directly into a position sizing formula. Here's how it works:

Step 1: Calculate your 1% risk amount. If your account is $50,000, your maximum risk per trade is $500.

Step 2: Identify your stop loss distance. If you're buying a stock at $100 and your technical stop is at $95, your stop distance is $5 per share.

Step 3: Calculate position size. Divide risk amount by stop distance: $500 ÷ $5 = 100 shares. This is your maximum position.

This formula adapts automatically. Wider stops mean smaller positions. Tighter stops allow larger positions. The constant is the dollar amount risked—always 1% of your account. You might own 50 shares of one volatile stock and 500 shares of a stable one, but both represent exactly the same dollar risk to your account.

## Trading Psychology: Why Risking Less Actually Makes More
The 1% rule does something profound for trading psychology: it removes fear. When you know the absolute worst outcome of any trade is a 1% account loss, you can think clearly. You can let winners run without the anxiety of giving back gains. You can cut losses quickly without the shame of admitting defeat.

Contrast this with traders risking 10% per trade. Every position becomes emotionally charged. Losses hurt so much that they hold losers hoping for recovery. Winners trigger such relief that they take profits too early. Fear and greed dominate every decision.

Jones understood that emotional stability is a competitive advantage. By mechanically limiting risk, he freed his mind to focus on market analysis rather than portfolio anxiety. The 1% rule isn't just about money management—it's about creating the psychological conditions for rational decision-making in an inherently irrational environment.
