Sequence of Returns Risk: Why WHEN You Retire Matters as Much as How Much
Two people can retire with the exact same average investment return over their careers and end up in very different places — because of the order those returns happened in, not the average itself.
The concept
Sequence of returns risk is the danger that a market downturn early in retirement — right when you start withdrawing money — does more lasting damage than the same downturn happening later, even if the long-run average return ends up identical. Withdrawing from a shrinking portfolio during a bad stretch locks in losses in a way that simply experiencing volatility while still contributing doesn't.
Why the order matters more than the average
While you're still working and contributing, a market crash is actually an opportunity — you're buying more shares at lower prices. Once you're withdrawing instead of contributing, that same crash forces you to sell more shares to generate the same income, permanently reducing how much is left to recover when the market eventually does.
Who's most exposed to it
The risk is concentrated in the first several years of retirement specifically — a downturn 15 years into retirement, after the portfolio has had years to grow, is far less damaging than the identical downturn hitting in year one or two, before any growth cushion has built up.
What actually helps against it
Common approaches include holding a cash or bond buffer specifically to cover a few years of expenses (so you're not forced to sell stocks during a downturn), reducing withdrawals temporarily during a bad market stretch rather than sticking to a fixed schedule, or simply building extra cushion above your bare-minimum retirement number so an early bad sequence doesn't derail the plan.
Why this matters even before you're close to retiring
It's a reason "I hit my number" isn't quite the same as "I'm actually ready" — the number itself doesn't account for what happens if the first few years go badly. Building in real margin, not just hitting a bare target, is part of what makes a retirement plan resilient to this specific risk.

Can sequence of returns risk be eliminated entirely?
Not completely — it's an inherent feature of withdrawing from a portfolio subject to market volatility. It can be meaningfully reduced through cash buffers and flexible withdrawal strategies, but not removed entirely.
Does this only matter for people retiring right before a crash?
It's most visible in that scenario, but the underlying risk exists for anyone withdrawing from investments during any period of poor returns, not just a dramatic single crash.
