Sequence risk is the uncomfortable fact that two retirees can earn the exact same average annual return over 30 years and end up with wildly different outcomes, purely because of the order those returns arrived in. If the bad years land early, while you are also withdrawing money to live on, the damage compounds in a way a strong average return cannot undo later. This is general information, not personalized financial or investment advice.
What changed in 2026
- More retirees are entering retirement after a volatile stretch of markets, which keeps sequence risk a live concern rather than a textbook example.
- Flexible-withdrawal frameworks have become more mainstream advice than the rigid fixed-percentage approach popular a decade ago, specifically to manage this risk.
- Longer retirements mean a longer exposure window — with people spending 25 to 30-plus years in retirement, the early-years risk zone still represents a meaningful fraction of the whole period.
Why the order of returns matters
Imagine two retirees, each averaging 6 percent a year over 25 years, each withdrawing a fixed dollar amount annually. If Retiree A hits two down years first, they are forced to sell a larger share of a shrinking portfolio just to cover spending — permanently reducing the shares left to benefit from the recovery. Retiree B, who gets the same two down years at the end of the 25-year stretch, has already spent down a much smaller portfolio by then and the late losses do far less damage. Same average, very different ending balance.
The danger window
Sequence risk is not spread evenly across a retirement — it concentrates in roughly the five years before and the first five to ten years after leaving work, sometimes called the retirement risk zone. Losses inside that window, combined with withdrawals, can permanently shrink what a portfolio can support for the rest of retirement. This is one reason a glide path's design matters so much right around a target date — see what is a glide path for how that mechanism intersects with this risk.

Practical defenses
- Hold one to three years of spending in cash or short-term bonds so a down year does not force stock sales at depressed prices — a bucket strategy formalizes this; see what is a bucket strategy for retirement.
- Adopt flexible, not fixed, withdrawals — trimming spending modestly in a down year materially reduces how many shares get sold cheap.
- Delay retirement or phase into it if a downturn hits right before your planned date, giving the portfolio time to recover before heavy withdrawals start.
- Consider guaranteed income such as delayed Social Security to cover baseline needs, reducing how much must come from a volatile portfolio in a bad early year; see Social Security claiming strategies.
FAQ
Does sequence risk apply while I am still working and saving?
Much less. During the saving years, downturns let you buy more shares cheaply; the risk is specific to the withdrawal phase.
Can a bond-heavy portfolio eliminate sequence risk?
It reduces it but does not eliminate it — bonds can also decline, and being too conservative introduces its own risk of running out of growth over a long retirement.
Is the 4 percent rule designed around this risk?
Partly. It was tested against historical worst-case sequences, not just average returns — see the 4 percent rule explained for the details.
How do I know if I am in the danger window right now?
Roughly five years on either side of your retirement date. If you are in that window, prioritize flexibility and cash buffers over precision.
