Sequence of Returns Risk

Why can two retirees earn the exact same average return over 30 years and end up in completely different places, one comfortable, one broke? The order of the returns. Sequence-of-returns risk is the danger that a market drop early in retirement, while you’re also pulling money out, does permanent damage that a later drop never could.

Why the order matters

While you’re saving, the order of returns barely matters. You’re adding money, so a crash early just means you buy cheap. Once you’re withdrawing, the math flips. A bad year early forces you to sell more shares to fund the same spending, and those shares are gone. They aren’t there to recover when the market bounces back. The same loss in year 25 is a footnote. In year two, it can be fatal.

A quick example

Two retirees each average 7 percent a year and each withdraw the same amount. One hits a steep loss in their first two years, the other hits the identical loss in their final two years. Same average, same withdrawals, same losses, just reordered. The one who got the bad years first can run out of money a decade early, while the other dies with plenty. Nothing changed but the timing.

The part most people miss

This is why the years right around your retirement date carry the most danger of your entire financial life, often called the fragile decade. People obsess over their average return and ignore that they have almost no control over which years are good. You can’t pick the sequence the market hands you. You can only build a plan that survives a bad one.

How to defend against it

The fixes all aim at one thing: don’t sell stocks into a downturn early on. Hold a cash and bond buffer to spend from when markets fall, so your stocks get time to recover. Stay flexible on spending in down years. And consider a guardrail withdrawal strategy, which dials spending up or down with the portfolio instead of locking in a fixed dollar amount.

You can’t control the order the market deals you. You can build a portfolio that doesn’t get knocked out by a bad opening hand.
