Most retirement planning discussions focus on average investment returns over long periods. But for retirees drawing income from their portfolios, the order in which those returns arrive matters enormously. A severe bear market in the early years of retirement can permanently impair the ability of a portfolio to sustain withdrawals for life, even if long-term average returns ultimately look respectable. This phenomenon is called sequence of returns risk, and it is one of the most important and underappreciated hazards facing people in the transition from accumulation to retirement.
At Q3 Advisors, we help clients understand and mitigate this risk as part of a comprehensive retirement income strategy.
What Is the Sequence of Return Risk?
Sequence of returns risk is the danger that negative investment returns occur at the wrong time — specifically early in retirement when withdrawals are being taken from a portfolio. The core problem is that withdrawals lock in losses during market downturns. When you sell investments to cover living expenses during a bear market, you sell more shares than you would at higher prices, leaving fewer shares to participate in any subsequent recovery. This ratcheting-down effect can permanently reduce the portfolio’s ability to sustain future withdrawals.
The best illustration of this risk is a comparison between two retirees who earn the same average annual return over 30 years, but in opposite sequences. Retiree A experiences strong gains in the early years and poor gains later. Retiree B experiences poor gains early and strong gains later. If both retire with the same starting balance and take the same withdrawals, Retiree B will run out of money far sooner — even though both averaged the same return. The same total growth, delivered in a different order, produces dramatically different outcomes once withdrawals begin.

This is why current research on safe withdrawal rates is more nuanced than the original 4% rule suggests. William Bengen revised his number upward to 4.7% in his 2025 book A Richer Retirement using a more diversified historical asset mix. Forward-looking analyses from Morningstar (2024) land closer to 3.7%, and Wade Pfau’s 2025 work suggests 3.3% to 3.5%. The disagreement is largely methodological — backward-looking history vs. forward-looking forecasts — but all three approaches share one underlying assumption: the sequence of returns matters more than the average.
Who Is Most Vulnerable to Sequence of Returns Risk?
Not everyone faces the same exposure. The sequence of returns risk is most acute for people who are actively drawing down their portfolio, particularly those who retired recently or plan to retire in the next few years. The five years before retirement and the first five to ten years of retirement represent the highest-risk window — what researchers call the “fragile decade.”
- New retirees with large portfolio withdrawals: The higher the withdrawal rate relative to the portfolio size, the more vulnerable the plan is to early market losses. A 5% or 6% initial withdrawal rate leaves very little cushion if a recession occurs in year one or two.
- Pre-retirees within five years of retirement: The years immediately before retirement are also vulnerable because a large portfolio loss just before you stop working can force you to retire later, lower your standard of living in retirement, or both.
- Those with no guaranteed income to cover baseline expenses: Retirees who depend heavily on portfolio withdrawals for all their living expenses are far more exposed than those who have Social Security, pensions, or annuity income covering essential costs. Guaranteed income reduces the amount you must withdraw from investments, dampening the impact of a market downturn.
- Those with large traditional IRA balances subject to RMDs: Required minimum distributions force withdrawals regardless of market conditions. A retiree who must take a large RMD during a down market is compelled to sell at a loss. RMDs begin at age 73 for those born between 1951 and 1959, and at age 75 for those born in 1960 or later under SECURE 2.0. Reducing future RMDs through proactive Roth conversions before the RMD age is a key risk mitigation strategy. See our guide to critical insights on Roth conversions and RMDs for how the math works in practice.
Strategies to Mitigate Sequence of Returns Risk
While no strategy eliminates market risk, several proven approaches can reduce the damage that early bear markets can cause to a retirement portfolio.
- Cash buffer or bucket strategy: Keep one to two years of living expenses in cash or short-term bonds, separate from your growth-oriented investments. This creates a reservoir to draw from during market downturns without selling equities at depressed prices. When markets recover, you replenish the cash bucket.
- Flexible withdrawal strategy: Plan to reduce discretionary spending modestly (10 to 15 percent) if the market declines significantly in early retirement. This reduces the number of shares you must liquidate during downturns, allowing more shares to recover when markets rebound. Michael Kitces’ research on dynamic withdrawal strategies suggests that even modest spending flexibility substantially improves portfolio survival in adverse return sequences.
- Guaranteed income floor: Ensure that your essential living expenses are covered by guaranteed income sources (Social Security, pension, or annuity income) rather than portfolio withdrawals. The less you must draw from investments each month, the less damage any market downturn can do to your long-term portfolio.
- Bond tent or rising equity glidepath: Wade Pfau’s research suggests that holding a higher allocation to bonds at the start of retirement and gradually increasing equity exposure later can outperform both static allocations and traditional stocks-decreasing glidepaths. The intuition is that the highest-risk window is the first decade of retirement, so equities can be safely raised once that window has passed.
- Asset location and diversification: Hold more conservative assets (bonds, TIPS, cash equivalents) in accounts from which you will withdraw first, and keep your longer-term growth assets in accounts you do not need to touch for a decade or more. This ensures that early withdrawals come from stable assets rather than volatile equities during a downturn.
- Delay Social Security where possible: Every year you delay Social Security past full retirement age (up to age 70) increases your benefit by approximately 8%. A higher guaranteed Social Security payment reduces your reliance on portfolio withdrawals, directly shrinking your exposure to sequence of returns risk.
Roth Conversions as a Sequence of Returns Risk Hedge
One of the most powerful and underused tools for managing sequence of returns risk is Roth conversion. When you convert traditional IRA or 401(k) assets to Roth, those funds grow tax-free and are not subject to required minimum distributions during the original owner’s lifetime. This gives you two distinct advantages.
First, Roth assets act as a long-term growth reservoir that you can choose when to tap, rather than being forced to draw on them by RMD rules. In a market downturn, you can leave Roth assets untouched and draw from cash buffers or stable bonds, allowing the Roth balance to recover.
Second, having a pool of Roth funds allows you to reduce mandatory distributions from your traditional IRA, which directly reduces the amount you must pull from the portfolio during any given market environment. This is the central reason multi-year Roth conversion planning is so valuable for IRA millionaires — it converts an inflexible RMD-driven distribution problem into a flexible, owner-controlled income strategy. Our multi-year Roth conversion framework walks through how this typically unfolds across a 5-10 year horizon.
In a down market, Roth conversions also become more attractive on a pure tax basis: you are converting shares at lower values, effectively moving more wealth into tax-free status for the same tax cost. A $100,000 conversion at a market low captures more shares (and therefore more recovery upside) than the same conversion at a market peak. Some advisors recommend intentionally accelerating Roth conversions during bear markets for exactly this reason. This approach requires careful tax planning to avoid bracket creep and IRMAA exposure, but the long-term benefit can be substantial for those with large traditional IRA balances. We cover this strategy in detail in our companion guide on Roth conversions during a down market.
Frequently Asked Questions
How do I calculate my personal sequence of returns risk?
A full analysis requires stress-testing your retirement plan against historical market sequences, including the worst sequences on record such as the periods starting in 1966, 2000, and 2008. Retirement planning software can model your specific withdrawal rate, asset allocation, and guaranteed income against thousands of possible future return sequences. The key output is a probability of portfolio success over your expected retirement horizon. Most planners target 80% to 95% success rates, with the right level depending on your spending flexibility and other guaranteed income.
Is sequence of returns risk the same as market risk?
No. Market risk refers to the possibility of investment losses in general. Sequence of returns risk is a specific form of market risk that applies to people making ongoing withdrawals. An investor who is still in the accumulation phase and not withdrawing from the portfolio is largely unaffected by sequence risk, because losses early on can be fully recovered if you are not selling shares to fund expenses. It is the combination of withdrawals and bad returns that creates the problem.
Does delaying retirement reduce sequence of returns risk?
Yes, for several reasons. Every additional year of work reduces the number of years your portfolio must sustain withdrawals, which mathematically improves portfolio survival probability. Working longer also allows you to continue contributing to retirement accounts and delay drawing down your portfolio, giving investments more time to recover from any pre-retirement bear markets.
Should I change my asset allocation to reduce sequence of returns risk?
Reducing equity exposure as you approach and enter retirement is one common approach, but dramatically reducing stock exposure can introduce a different problem: your portfolio may not grow fast enough to sustain 25 to 35 years of withdrawals with inflation. Most current research, including Wade Pfau’s work on rising equity glidepaths, suggests that a U-shaped allocation — more conservative at the start of retirement, gradually rising back to higher equity exposure later — outperforms both very aggressive and very conservative fixed allocations.
Are Roth conversions during a market downturn really worth it?
Often yes. A market low is one of the most tax-efficient times to convert, because the same dollar amount of conversion captures more shares than it would at a market peak. When the market recovers, all that recovery happens inside the tax-free Roth account. This is one of the few situations where a market downturn creates a genuine planning opportunity rather than purely a problem. The catch is that the conversion still triggers ordinary income tax in the conversion year, so the strategy requires careful coordination with your bracket and IRMAA planning. See our companion piece on Roth conversions during a down market for the full framework.
