Maximum drawdown: the metric that measures pain
Maximum drawdown is the largest peak-to-trough drop. It measures the worst pain a strategy has inflicted — and whether you could survive it.

Average return tells you the destination. Maximum drawdown tells you how bad the journey got — and the journey is what makes people quit. It may be the single most useful number for judging whether you can actually live with a strategy.
What it measures
Maximum drawdown (MDD) is the largest peak-to-trough decline a strategy (or account) has experienced — how far it fell from a high point before recovering. A strategy that averaged a nice annual return but, along the way, dropped 60% from a peak had a 60% maximum drawdown. That's the depth of the worst hole it put you in.
The gain you need just to break even after a loss
Why it matters more than the average
Two strategies can have identical average returns and wildly different drawdowns — and the drawdown is what determines whether you stick around to collect the average. Reasons MDD is so revealing:
- It's where people quit. Most traders abandon a strategy at its worst moment — the bottom of the drawdown — locking in the loss right before any recovery.
- It connects to the recovery math. A 60% drawdown requires a 150% gain to recover. Deep drawdowns aren't just painful; they're mathematically expensive to climb out of.
- It exposes hidden risk. A smooth-looking average can mask a strategy that occasionally falls off a cliff.
Using it
- Judge a strategy by its drawdown, not just its return. Ask "could I have held through the worst stretch?" — honestly.
- Right-size to the drawdown you can stomach. A strategy you'll abandon at the bottom is worthless to you, however good its average.
- Remember the future drawdown may be worse than the past one. History shows you a sample, not a ceiling.
Returns are what a strategy promises. Maximum drawdown is what it asks of you in return. The best strategy in the world does you no good if its worst day makes you quit — so know the worst day before you start.
