Sequence-of-returns risk near retirement
See how early market losses can damage a retirement portfolio when withdrawals begin, even when long-term average returns look identical.
Sequence risk is easiest to understand as a chain of events: a decline, a withdrawal, fewer assets in the recovery, and less room later.

Why an early loss changes the math
A simplified two-step example isolates the effect of withdrawals during a decline.
Start
A $1,000,000 portfolio falls 20% to $800,000.
Withdraw
A $40,000 withdrawal leaves $760,000 invested.
Recover
A subsequent 20% gain lifts $760,000 to $912,000 - Not to the $960,000 that would remain if no withdrawal had occurred after the loss.
Order matters after withdrawals start
Before retirement, a poor early market can be offset by later contributions and recovery. After withdrawals begin, selling into an early decline removes assets that cannot participate in a rebound. Two portfolios can earn the same average return and still end with very different balances because the order of returns differs.
Planning lens: Average return alone is incomplete.
A practical stress test
Run at least three sequences: steady returns, poor returns in the first five years, and poor returns later. Keep the same long-run average to isolate sequence risk. Compare whether essential spending remains covered and note when the portfolio first requires an adjustment.

Design responses before a downturn
Useful defenses can include a lower starting withdrawal, a reserve for near-term spending, flexible discretionary withdrawals, broader diversification, or part-time income. None is free: cash can reduce expected return, flexibility changes lifestyle, and guaranteed income can reduce liquidity. The plan should show the cost of each defense.

Know which withdrawals create the risk
Sequence risk matters when money leaves a volatile portfolio, so the withdrawal calendar is as important as the return path.
Mark unavoidable withdrawals
List essential spending and known large payments for the first years of retirement. These amounts need a funding plan that does not assume stocks recover on schedule.
Keep flexible spending separate
Travel, gifts, and projects may be paused or reduced after a poor market. Write the trigger, amount, and duration of a cut before a decline makes the conversation emotional.
Test the refill rule
A reserve can reduce forced sales, but it eventually needs to be refilled. Decide whether strong returns, portfolio income, or rebalancing will replenish it and how often the rule is reviewed.
What to save with the stress test
Keep the starting balance, withdrawal amount, asset mix, return sequence, and the first year an adjustment was needed. Save the exact response tested beside each result. A label such as 'bad market' is not enough. The record should show whether the plan used cash, reduced flexible spending, changed withdrawals, or added income, and how long that response lasted.
Choose a defense you could actually use
Record the spending adjustment, reserve, income source, or allocation response that would apply after an early decline and name its cost.
Connect this decision to your plan
A useful retirement plan is not one perfect number. It is a set of assumptions, a gap you can measure, and actions you can revisit each year. Use the full retirement planning framework to keep this choice connected to the rest of the topic.
