Maximum Drawdown
Maximum drawdown is the largest peak-to-trough decline in equity — the single most painful stretch of a strategy’s life. It decides whether you can actually hold the system.
Returns tell you how the story ends; max drawdown tells you its darkest chapter: the largest percentage slide from an equity peak to the subsequent trough. Two strategies both earning 15% annualized — one with a 10% max drawdown, the other 45% — are completely different products: most people abandon the second long before the ending.
Drawdown damage is nonlinear: −10% needs +11% to recover, −30% needs +43%, −50% needs +100%. Deep drawdowns destroy more than compounding — they destroy execution. Nearly every “quit the system at the exact bottom” story happens in the very week the max drawdown sets a new record.
When evaluating a strategy, read max drawdown alongside drawdown duration (months from peak to recovery), and assume the future max will likely exceed the historical one — a backtest estimates the floor, not the ceiling. The return-to-drawdown ratio (annualized return ÷ max drawdown) is a far more honest scorecard than returns alone.
The levers that tame drawdown are the other tools in this glossary: cycle-state filtering (cut exposure in Downtrends), macro resonance (de-leverage into headwinds), position sizing and stop discipline. CycleMaster’s historical replay lets you see exactly how painful a playbook’s worst stretch was before you commit to it — which matters far more than admiring its equity curve.
FAQ
It depends on the capital’s nature and your tolerance, but one empirical red line: drawdowns beyond 30% make the vast majority of people abandon the system. A common design target keeps expected max drawdown within 1–1.5× the annualized return.
The three most effective levers: state filtering (full size only with the trend at your back), volatility-targeted sizing (auto-reduce in turbulence), and diversification across low-correlation symbols. All three cost some return — drawdown control is fundamentally buying survival with yield.
