Sequence of Returns Risk: Why the First 5 Years of Retirement Matter Most
Average returns do not decide whether your money lasts — the order of those returns does. Early losses combined with withdrawals can cripple a plan that looks fine on paper.
Two retirees, same average return, opposite outcomes
Imagine two retirees who each earn an identical 7% average annual return over 30 years and withdraw the same inflation-adjusted amount. One faces a bear market in years 1–3; the other hits the same bear market in years 25–27.
The late-bear retiree finishes comfortably. The early-bear retiree can run out of money in their 80s — with the same average return. That is sequence of returns risk: when you are withdrawing, the order of returns matters as much as the average.
Why early losses hurt so much
Withdrawals during a downturn force you to sell more shares at depressed prices. Those shares are gone permanently — they cannot participate in the recovery. The math compounds: a portfolio that drops 30% while funding withdrawals needs far more than a 43% rebound to get back on track.
Accumulators experience the same markets in reverse: for someone still saving, an early bear market is actually helpful (cheap shares). The risk flips at the moment withdrawals begin — which is why the five years before and after retirement are called the fragile decade.
Five practical defenses
- A cash-and-bonds buffer. Holding 1–3 years of spending in short-term reserves lets you skip selling stocks during a drawdown.
- Flexible spending rules. Trimming withdrawals even 10% during bad markets dramatically improves survival odds — guardrail strategies formalize this.
- A rising equity glidepath. Starting retirement slightly more conservative and re-risking later concentrates safety in the fragile years.
- Guaranteed income floors. Social Security (especially delayed claiming), pensions, or annuitized income cover essentials so market losses never force fire sales.
- Part-time income early on. Even modest earnings in the first years sharply cut the shares you must sell at the worst time.
How to measure your exposure
A straight-line projection using average returns will never show sequence risk — it assumes the same return every year. Two tools do reveal it:
- Monte Carlo simulation runs your plan through a thousand randomized return sequences and reports the percentage that succeed.
- Stress testing replays specific bad scenarios — an immediate bear market, a high-inflation decade — against your exact plan.
The bottom line
You cannot control the market's order of returns — but you can control how exposed your plan is to an unlucky draw. Test your plan against bad sequences before they happen, and build the buffers while you still have choices.
