What is maximum drawdown?

Last updated June 4, 2026 · ~5 min read

Maximum drawdown is the worst peak-to-trough fall an investment suffered over a period. If a return tells you how the story ended, drawdown tells you how bad it got along the way — the part a headline number quietly leaves out.

The definition

Maximum drawdown (often 'max DD') is the largest percentage drop from a previous high point to a later low point, before a new high is reached:

Max drawdown = (Trough − Peak) ÷ Peak

A max drawdown of −80% means that, at the worst moment, the investment had lost 80% of its value relative to its best prior level.

Why it matters more than it looks

A drawdown is not an abstract statistic — it is the loss you would actually have been staring at in your account. It is what tests conviction, and it is the single biggest reason people sell at the bottom and never see the recovery.

A 50% loss also needs a 100% gain just to break even, so deep drawdowns do lasting damage even when the percentage 'sounds' symmetric.

Real examples

The scenarios on this site make the point vividly. Solana ended enormously higher from a 2021 start — yet it fell roughly 96% from its peak along the way. Bitcoin bought in early 2018 dropped about 76% before recovering. Even the assets that 'won' put their holders through brutal declines first.

That is the honest counterweight to a 'what if I'd invested' headline: the same position that delivered the big number also demanded the stomach to hold through a near-total loss.

How to use it

Treat max drawdown as a stress test before you commit. Look at an asset's worst historical fall and ask honestly: if that happened the week after I bought, would I hold — or would I panic-sell? Your real risk tolerance is whatever survives that question.

And remember it is backward-looking. A small historical drawdown does not promise future calm; it only tells you what has happened so far.

FAQ

Does maximum drawdown predict future losses?

No. It is purely historical — the worst fall that already happened over the measured window. A future drawdown could be smaller or larger.

Is a smaller drawdown always safer?

Generally, lower-risk assets show smaller drawdowns — but a calm history is not a guarantee. Conditions change, and an asset that was placid can still fall hard.
