Most investors are taught to think about return averages. Over the long run, the S&P 500 has averaged roughly 9–10% per year. A balanced 60/40 portfolio has averaged something a bit lower. People plan their retirement around these long-run averages, and for the most part, that works fine — during accumulation. The math of compounding is forgiving when you’re contributing rather than withdrawing.
The moment you flip from contributing to withdrawing, the rules change. Suddenly the order of your returns matters as much as the average. Two retirees with identical starting balances, identical withdrawal rates, and identical 30-year average returns can end up in radically different places. One retires comfortably; the other runs out of money. The only difference between them is which years had the big drawdowns.
This is sequence-of-returns risk, and for anyone within roughly five years of retirement on either side, it is the single most important risk in personal finance — bigger, in expected dollar impact, than fees or taxes.
What sequence risk actually is
Imagine two retirees. Both start with $1 million. Both withdraw $50,000 per year (a 5% initial rate), increasing with inflation. Both earn an average of 7% per year over 30 years. The numbers are illustrative; the structural lesson holds at any non-trivial assumption.
The difference: the order of their returns is reversed.
- Retiree A has bad years early — say, three consecutive 20% drawdowns in years 1–3 — followed by a steady recovery and good years late.
- Retiree B has the same return sequence in reverse — good years early, the same three 20% drawdowns at the end.
Same average. Same withdrawals. Same starting balance. After 30 years, the outcomes are not close. Retiree A — who hit the drawdown first — typically runs out of money in the back half of retirement. Retiree B — who got the early-year tailwind — finishes with a portfolio larger than they started with, even after three decades of withdrawals.
Why? Because the dollars Retiree A took out at the bottom of the early drawdown can never come back. They’re spent. Whatever the recovery does for the remaining portfolio, it does for a smaller base. Retiree B, by contrast, was withdrawing from a portfolio that had already grown — the early-year gains did the heavy lifting before any withdrawals turned into permanent capital loss.
The single most important sentence about sequence-of-returns risk: withdrawing from a portfolio that’s down is mathematically not the same as withdrawing from a portfolio that’s up. The first locks in the loss. The second doesn’t.
A simple worked example
To make this concrete, here is a stylized two-portfolio comparison. Both retirees start with $500,000 and withdraw $25,000 per year (no inflation adjustment, for simplicity). Both have the same set of three returns over three years: −20%, 0%, +30%. The arithmetic average of those three years is roughly +3.3%.
| Retiree | Year 1 | Year 2 | Year 3 | End balance |
|---|---|---|---|---|
| A — Bad year first | −20% → $375,000, then withdraw $25k → $350,000 | 0% → $350,000, withdraw $25k → $325,000 | +30% → $422,500, withdraw $25k → ~$397,500 | ~$397,500 |
| B — Good year first | +30% → $650,000, withdraw $25k → $625,000 | 0% → $625,000, withdraw $25k → $600,000 | −20% → $480,000, withdraw $25k → ~$455,000 | ~$455,000 |
Same withdrawals. Same returns. Same arithmetic average. Different starting-position-relative-to-each-year. Retiree B ends with about $57,500 more — over a 14% gap on the ending balance, generated entirely by the order of identical returns. Stretch that to a 30-year retirement and the gap widens to numbers that change the kind of retirement someone has.
Why this is so much worse in retirement than during accumulation
The mirror image is also true and worth making explicit. Sequence risk is asymmetric. It barely matters during accumulation. It dominates during withdrawal. Here’s why.
During accumulation — when you are saving and not taking money out — a market drawdown is, on net, an opportunity. Your existing balance is down, but your ongoing contributions are buying shares at lower prices. When the market recovers, your portfolio comes back, and the contributions made at the bottom turn into outsized gains. A bad early-career year is not a permanent setback — it is, mathematically, often a mild positive over a 30-year contribution horizon.
During withdrawal, the dynamic is exactly reversed. A drawdown forces you to liquidate shares at depressed prices to fund living expenses. Each share sold at the bottom is a share that cannot recover, by definition — it is no longer in the portfolio. The recovery, when it comes, applies only to what’s left. The shares you spent are gone forever, and so is the future compounding they would have produced.
This is why financial-planning research has identified what is sometimes called the retirement red zone — roughly the last five years of accumulation and the first five years of retirement. A bad market period inside this ten-year window does more damage to a retirement plan than the same bad period at any other point in an investing lifetime. Outside the red zone, sequence risk is real but manageable. Inside it, it is structural and load-bearing.
The numbers behind the red zone
Three intuitions help frame why this window matters.
One, by the time someone reaches the last five years of accumulation, their portfolio is typically at its largest absolute size — and therefore drawdowns produce their largest absolute dollar losses of an investing lifetime. Losing 30% of $200,000 is unpleasant. Losing 30% of $2 million is qualitatively different.
Two, the portfolio at this point has limited time to recover before withdrawals begin. A 30% drawdown at age 35 has 30 years to compound back. The same drawdown at age 60 has perhaps five years before withdrawals start, and any recovery has to happen while the portfolio is being drawn down. Recovery becomes structurally harder.
Three, the early years of retirement — when the new retiree is most psychologically vulnerable to fear, when the rhythm of withdrawing instead of saving is unfamiliar, and when the cumulative effect of a few bad early years compounds for decades — are precisely when behavioral mistakes are most expensive. The behavioral tax (which we discuss in the math of compounding) is at its highest leverage point in the red zone.
The good news is that the red zone is identifiable. You know roughly when you’re in it. And there are concrete things to do about it.
What you can actually do about sequence risk
The defenses against sequence risk fall into four buckets, in rough order of importance.
1. Hold a meaningful cash and short-duration bond reserve
The single most effective defense is straightforward: hold one to three years of expected withdrawals in cash, money-market funds, short-duration Treasuries, or short-duration high-quality bonds. When the equity portion of the portfolio is down, you draw from the reserve. When the equity portion has recovered, you replenish the reserve from gains. You never sell stocks at the bottom because you don’t have to.
This is sometimes called a “cash bucket” or, when extended into bonds, a “bond tent” — gradually increasing your fixed-income allocation in the years approaching retirement, then gradually decreasing it again as the equity portion has more years to do its work. The idea is to be most defensive precisely when sequence risk is highest, then loosen up once you’re through the red zone. The exact dollar amount and duration depend on your situation; the structural idea is to remove the forced sale at the bottom.
2. Use a flexible withdrawal strategy, not a rigid one
The classic 4% rule (which we’ll cover in a future piece) was built on a simple assumption: you withdraw 4% of your initial balance, then increase that dollar amount with inflation every year, regardless of what the market does. It’s a useful starting point but it’s brittle exactly when sequence risk hits hardest, because it forces you to keep withdrawing the same inflation-adjusted dollars even after a bad year.
A flexible strategy says: in years following large market drawdowns, take a smaller withdrawal (or skip the inflation adjustment); in years following large market gains, take a normal withdrawal or replenish reserves. Even modest flexibility — pausing the inflation adjustment for a year or two after a 20% drawdown — meaningfully extends the longevity of a portfolio under sequence stress. The cost is a slightly leaner standard of living in tough years; the benefit is dramatically lower probability of running out late in life.
3. Match your equity allocation to your real time horizon
A 65-year-old planning for a 30-year retirement is not, in any meaningful sense, an “old” investor. Their median expected lifespan still has three decades of compounding ahead. Many retirees over-correct the other direction, moving aggressively to bonds and cash at retirement and starving themselves of long-term growth that would otherwise outpace inflation.
The defensible balance is usually to stay meaningfully exposed to equities throughout retirement — the question is which equities. Lower-volatility, dividend-paying, quality-business exposure tends to produce shallower drawdowns and therefore less sequence damage than higher-volatility growth-stock exposure, even when the long-run averages of the two are similar. This is the same insight from the compounding white paper: shallower drawdowns mean less volatility drag, which means more terminal wealth.
4. Sequence-aware income sources
Social Security, pension income, annuity income, and other guaranteed income streams are not subject to sequence risk in the same way. A monthly Social Security check arrives whether the market is up or down. The more of your retirement spending that is covered by these flooring sources, the less the equity portion of your portfolio is being asked to fund withdrawals during drawdowns. Coordinating Social Security claiming, pension elections, and any annuity allocation is part of the sequence-risk toolkit. Delaying Social Security to 70, when feasible, has the side benefit of reducing the burden on the portfolio in the years it is most exposed.
What sequence risk is not
A few clarifications, because the topic gets confused with related concepts.
Sequence risk is not the same as market risk. Market risk is the risk that markets fall. Sequence risk is the risk that markets fall at the wrong time relative to your withdrawal schedule. Two retirees can experience the same total market path with completely different outcomes if their withdrawal patterns differ.
Sequence risk is not eliminated by long horizons. A common counterargument is “in the long run, markets recover.” Sometimes true, but irrelevant — the retiree who liquidated shares at the bottom doesn’t own those shares anymore. They aren’t in the recovery. The “long run” healed the index; it did not heal that retiree’s portfolio.
Sequence risk is not the same as inflation risk. Inflation is its own compounding machine, also discussed in the compounding white paper. Sequence risk and inflation risk can compound on each other — a stagflationary period (poor real returns combined with high inflation) is the worst possible sequence environment because both forces work against the portfolio simultaneously. The 1970s remain the canonical case study.
How TTCM thinks about sequence risk
The defenses above are not exotic, and most of them are visible in how we structure portfolios for clients in or near the red zone.
We focus on quality businesses and durable cash flows because shallower drawdowns mean less sequence damage. The math from the compounding white paper carries over directly: a portfolio that loses 25% in a bad year is in much better shape to fund withdrawals than one that loses 50%.
We hold adequate cash and short-duration reserves for clients in or approaching the red zone — typically calibrated to one to three years of expected distributions, depending on the client’s situation, other income sources, and risk tolerance. The reserve is the operational answer to “what do you withdraw from when the market is down?” The answer is: not the equity portion.
We pay attention to withdrawal flexibility. Most of our retiree clients work with us on a withdrawal plan that responds to market conditions rather than running on rigid autopilot. In years following major drawdowns, we have the conversation about whether to take a smaller distribution or skip an inflation adjustment, and the math is laid out so the trade-off is concrete.
We coordinate with Social Security claiming and other income sources when relevant. A delayed Social Security claim is, mathematically, one of the cheapest forms of inflation-protected lifetime income available — and it directly reduces the burden on the portfolio during the red zone.
And we frame the behavioral conversation before the storm, not during it. The most expensive moment in a retirement plan is the panic decision in the first bad year. The job of a fiduciary adviser is to make sure that decision has been thought through in advance, that the cash reserve is sized for exactly that scenario, and that the client understands why the plan they signed up for in calmer times still applies.
