Maximum drawdown looks like a simple number: the largest decline from a local peak to the following trough. Without duration, recovery shape, and position-level risk, however, it can create a false sense of safety.
What drawdown actually measures
If equity rises from 100,000 to 120,000 and then falls to 108,000, the drawdown is 10%. It is measured from the achieved peak, not from starting capital. A profitable period can therefore contain a painful decline inside it.
The metric answers one narrow question: how far equity moved below its previous high. It does not describe how long the decline lasted, how quickly it happened, or how long recovery took. Those dimensions must be inspected separately.
Depth is only one coordinate
Two strategies can both show an 8% drawdown and feel entirely different. One loses it in a day and recovers a week later; the other declines for four months. The headline number is identical, while the psychological burden and liquidity needs are not.
How many calendar and trading days did the decline last?
How quickly did equity return to the prior high?
How much of the loss came from one trade or instrument?
Did similar episodes appear in other market regimes?
Turn the percentage into a decision
Read drawdown beside return, history length, and trade count. Then convert the percentage into money. If that loss would make you abandon positions at the worst moment, the allocation is too large.
Drawdown is not a penalty attached to return; it describes the path taken to achieve it. A sound risk level is one at which you can still follow a predefined process.
