Maximum Drawdown Explained
Maximum drawdown explained—peak-to-trough losses, recovery math, position sizing, correlation, and risk management.
Maximum drawdown is the largest peak-to-trough decline in an account, portfolio, or strategy over a period of time. If an account rises to $10,000 and falls to $8,000 before recovering, the drawdown is 20%.
Drawdown matters because survival matters. A strategy can have good trades and still be unusable if losses cluster too deeply.
How drawdown works
| Account path | Drawdown |
|---|---|
| $10,000 peak to $9,000 low | 10% |
| $10,000 peak to $8,000 low | 20% |
| $10,000 peak to $7,000 low | 30% |
Recovering from drawdown takes larger percentage gains than the loss itself. A 50% drawdown needs a 100% gain to recover.
Why maximum drawdown matters
- Shows strategy stress.
- Reveals whether position sizing is too aggressive.
- Helps compare systems.
- Protects psychology.
- Prevents one theme from damaging the whole account.
Drawdown is connected to risk management rules, position sizing, and correlation.
How to reduce drawdown risk
- Risk less per trade.
- Avoid correlated positions.
- Use clear invalidation.
- Reduce size during losing streaks.
- Avoid trading through events you do not understand.
- Diversify exposure thoughtfully.
No rule removes losses. The goal is to keep losses survivable.
