Sequence-of-returns risk
· Concept or strategy
Watch outA common mistake, trap or scam.
The danger that a market crash early in retirement, while you are withdrawing, permanently shrinks a portfolio.
See it on the Personal Finance & Estate map →How it works
Two retirees with the same average return can end very differently. Take $1 million with $50,000 withdrawn yearly: a 30% drop in year one leaves $650,000, which then needs a 54% gain just to get back. The same drop in year 20 hurts far less. Defenses: two to three years of spending in cash or bonds, flexible withdrawals, a guaranteed income floor, and delaying Social Security. Red flags for parents: all stocks near retirement, or a salesperson using crash fear to push a product.
Why it matters for you
Watch out: it is the risk the 4% rule was sized around, and panic-selling makes it permanent. Ask a fee-only planner to stress-test any plan.
Think of it like
Like a big vacancy right after a refinance: same lost rent as one in year 20, but it hits when reserves are thinnest.
Red flags and protection
Historical backtests (Bengen, 1994; the Trinity study, 1998) show retirees starting around 1929 and 1966 fared worst; Monte Carlo studies by Morningstar and others agree.
Watch out for
How much a cash buffer or 'bucket' strategy actually helps, versus simply lowering withdrawals, is still argued.

▸Sequence-of-returns risk is a major early-years danger in Retirement income planning (savings into paychecks)Watch out
How they connect
Once withdrawals start, early losses compound: you sell shares low to pay bills, leaving less to recover. That is why retirement income plans hold a cash or bond reserve, keep spending flexible, and build a guaranteed floor. Red flags for a parent: fully in stocks near retirement, or panic-selling after a crash.
When it applies
Most dangerous roughly five years before and ten years after retiring, sometimes called the retirement 'red zone'.
How sure?
Kitces (2008) found real returns in a retirement's first 15 years largely predict its safe withdrawal rate; Monte Carlo studies agree.
Watch out for
How big the reserve should be, and whether bucket strategies beat a simple rebalanced portfolio, is still argued.
▸The 4% rule (safe withdrawal rate) was calibrated to withstand Sequence-of-returns riskStandard practice
How they connect
Bengen picked 4% because it survived the worst sequences in US history, such as retiring just before the 1966–82 stretch of poor real returns. So the rule is built around sequence risk, but a future sequence worse than any in the record could still break it.
When it applies
Bengen's 1994 study; the worst historical start years were around 1966–1968, when stagnant markets met high inflation.
How sure?
Backtests on long-run US data (Ibbotson, Shiller) show starting years, not average returns, decided which portfolios failed.
Watch out for
Whether non-US history, where some markets did far worse, is the better guide is debated; global data give lower safe rates.
▸Sequence-of-returns risk is cushioned by Bonds: Treasuries, T-bills, TIPS, I bonds & munisStandard practice
How they connect
A crash early in retirement does lasting damage if stocks must be sold to pay bills. Holding several years of spending in bonds, T-bills or cash lets retirees draw from them during a downturn and leave stocks time to recover.
When it applies
Identified in William Bengen's 1994 safe-withdrawal research; 'bond tent' and bucket strategies refined by planners such as Michael Kitces and Wade Pfau.
How sure?
Historical simulations, from Bengen in 1994 to later work by Kitces and Pfau, show early losses drive most failed retirement plans.
Watch out for
How large the buffer should be, and whether shifting back toward stocks after retirement helps, are debated.
