Maximum Drawdown: Why the Worst Loss Matters More Than the Average Return

5 min read · Updated 2026-06-15

Returns get the headlines, but maximum drawdown is the number that decides whether you actually stay invested. It's the largest peak-to-trough drop your portfolio suffered — the deepest the value fell before recovering.

Understanding it is the difference between a portfolio that looks good on paper and one you can hold through a real downturn.

What maximum drawdown is

Maximum drawdown measures the worst loss from a previous high to the following low, expressed as a percentage. If a portfolio peaks at $100,000 and falls to $65,000 before recovering, that's a 35% maximum drawdown. It captures the worst-case pain over a period in a single number.

Why it matters more than average return

A portfolio with a great long-run return is worthless if you bail out at the bottom — and big drawdowns are exactly what trigger panic selling. The average return tells you the destination; the drawdown tells you whether you'll survive the journey without giving up. For most real investors, the second one decides the outcome.

Drawdown is not the same as volatility

Volatility measures how much returns wobble month to month; drawdown measures the cumulative damage of a sustained decline. A portfolio can have modest volatility and still suffer a deep, slow drawdown over a long bear market. Both matter, but drawdown is the one that maps to “how bad did it actually get.”

Recovery time matters too

A 50% drop needs a 100% gain to get back to even — which is why deep drawdowns can take years to recover. The time spent “underwater” (below the previous high) is its own kind of pain, especially if you're withdrawing money during it. A good analysis shows both the depth and the recovery length.

How to measure yours

Backtest your portfolio and look at the maximum drawdown and recovery period, then stress-test it against specific crises (2008, 2020, 2022) to see the real worst case for your exact holdings — before the market shows you live.

FAQ

What is a good maximum drawdown?
Lower is better, but it's relative to the assets you hold — an all-stock portfolio has historically seen ~50%+ drawdowns, while a balanced mix is shallower. The key is that your worst-case drawdown is one you could actually tolerate without selling.
What's the difference between drawdown and volatility?
Volatility measures how much returns bounce around month to month; drawdown measures the worst peak-to-trough loss. A portfolio can be low-volatility and still have a deep, drawn-out drawdown.
How long does it take to recover from a drawdown?
It depends on the depth: a 50% loss requires a 100% gain to break even, which can take years. Recovery (underwater) time is as important as the depth, especially in retirement.
