Most blown accounts don’t die from bad analysis. They die from good analysis sized recklessly — one oversized trade that turns a normal loss into a crater. Position sizing, not stock picking, is what keeps you in the game.
The 1% rule is the simplest guardrail in trading: never risk more than 1% of your account on a single trade. It sounds conservative until you do the math on what it actually protects you from.
What ‘Risking 1%’ Actually Means
Risking 1% doesn’t mean buying with 1% of your account. It means structuring the trade so that if your stop is hit, you lose 1% of your account — no more. Your position size is whatever makes that true, given the distance from your entry to your stop.
The formula is simple: account risk in dollars, divided by your risk per share/contract (the distance to your stop), equals your position size. The stop comes first; the size is derived from it — not the other way around.

What 1% Risk Looks Like by Account Size
1% of the account is your maximum loss per trade (shown in $). Everything else — share count, contracts — is sized to keep the loss at that line.
Sizing a Trade Step by Step
Once you fix your dollar risk, the position size falls out of the stop distance. Here’s the same $10,000 account ($100 risk) sized across different stop distances — note how a wider stop means a smaller position, not more risk.
| Account | 1% risk | Stop distance | Position size |
|---|---|---|---|
| $10,000 | $100 | $0.50 / share | 200 shares |
| $10,000 | $100 | $1.00 / share | 100 shares |
| $10,000 | $100 | $2.00 / share | 50 shares |
| $10,000 | $100 | $1.00 / contract* | ~1 contract |
*Options multiply by 100, so a $1.00 stop on one contract is roughly $100 of risk. The mechanics differ, but the principle is identical: size so the worst case equals your fixed risk.
Why 1% Survives Losing Streaks
The real power of small, consistent risk shows up across a streak of losses. At 1% per trade, even ten losses in a row leaves you down about 10% — annoying, fully recoverable, and your decision-making stays intact. Risk 10% per trade and that same streak is account-ending.

Account Remaining After 10 Straight Losses
Same ten losses, three different risk levels. Small risk turns a brutal streak into a survivable dip; large risk turns it into a blow-up.
Make It a Rule, Not a Mood
Position sizing only works if it’s mechanical. The moment you size by conviction — ‘I really like this one’ — you’ve reintroduced the exact emotion the rule exists to remove. Decide your percentage, compute the size every time, and let the consistency do the work.
- Set the stop first; derive size from it
- Keep risk per trade small and constant (many use 1%)
- Wider stop = smaller position, never more risk
- Never up-size by conviction — keep it mechanical
