Protecting Your Portfolio When It Matters Most
The first decade of retirement is the most critical period for your financial security. While you’ve spent years building your nest egg, how you manage withdrawals during those early retirement years will largely determine whether your savings last a lifetime or run out prematurely.
The primary threat? Sequence of returns risk—the danger that poor market performance early in retirement will permanently damage your portfolio’s ability to sustain you through your lifetime.
What Is Sequence of Returns Risk?
Imagine two investors, each retiring with $1 million and withdrawing $50,000 annually, adjusted for inflation. Both earn an average annual return of 4% over 30 years. The only difference: one experiences negative returns in the first five years, followed by strong gains later. The other gets the identical returns but in reverse order—good years first, bad years later.
Despite identical average returns, the first investor runs out of money in year 26, while the second maintains a healthy portfolio throughout retirement. This stark difference illustrates why the sequence of returns matters profoundly once you begin withdrawing funds.
Why Early Returns Matter So Much
During your working years, the order of returns is largely irrelevant. If the market drops 30% when you’re 35, you’re actually buying stocks “on sale” with your contributions. Time allows recoveries to compound in your favor.
In retirement, this dynamic shifts critically. If you’re drawing funds while the market declines, you risk “permanent portfolio damage.” This occurs because selling assets at depressed values to cover living costs depletes your capital, leaving fewer shares to rebound when the market eventually recovers.
Historical Lessons: The 1973-1974 Scenario
Financial planner William Bengen pioneered the study of safe withdrawal rates by analyzing actual market data from 1926 forward. His research revealed that a 4% initial withdrawal rate (originally 4.15%, later upgraded to 4.7%) sustained portfolios of 60% stocks and 40% bonds for at least 30 years in most historical periods.
However, certain retirement cohorts faced disaster—specifically, those who retired during elevated market valuations followed by sustained bear markets combined with high inflation.
The most devastating period wasn’t the Great Depression, despite the spectacular 1929 crash. Why? Deflation actually increased the purchasing power of cash during the 1930s. Instead, the 1973-1974 recession proved catastrophic. The S&P 500 declined 48% on an inflation-adjusted basis over two years. Meanwhile, inflation that began 1972 at 3.4% peaked at 13.5% by 1980.
This toxic combination—declining portfolios requiring larger share sales to meet fixed dollar withdrawals while inflation eroded purchasing power—decimated retirement accounts. Investors who retired in early 1973 exhausted their portfolios in just 23 years, despite what eventually became reasonable long-term market returns.
Over the period from 1926 through 2024, the S&P 500 delivered inflation-adjusted returns of approximately 7.2% annually. However, this average masks extraordinary variability, particularly during early retirement when sequence risk matters most.
Valuation and Inflation: Personalizing Your Safe Withdrawal Rate
Recent research by Bengen and financial planner Michael Kitces reveals that safe withdrawal rates vary dramatically based on two measurable factors: stock market valuation at retirement and the prevailing inflation environment.
The Shiller Cyclically Adjusted Price-Earnings (CAPE) ratio provides a valuation measure that predicts subsequent ten-year returns with reasonable accuracy. When combined with inflation trends, these metrics allow for more personalized safe withdrawal calculations than the universal 4% rule.
Bengen identified four inflation regimes: deflation (below 0%), low inflation (0% to 2.5%), moderate inflation (2.5% to 5%), and high inflation (above 5%). Safe withdrawal rates—what Bengen terms “SAFEMAX”—vary substantially based on starting conditions.
For example, a retiree beginning with a Shiller CAPE of 14.8 during moderate inflation could safely withdraw 7.24% initially. However, someone facing a CAPE of 22.3 in the same inflation environment would be limited to just 5.54%. This difference reflects that expensive markets deliver lower subsequent returns, providing less cushion for withdrawals.
Portfolio Strategies to Reduce Sequence Risk
Financial advisors have developed multiple approaches specifically designed to protect against sequence risk during critical early retirement years.
Balanced Asset Allocation
The most fundamental approach maintains a balanced allocation between stocks and bonds, typically 60% equities and 40% fixed income. This diversification reduces volatility compared to all-stock portfolios. Because stocks and bonds often move inversely, a balanced portfolio provides natural stabilization.
Bengen’s research demonstrates that portfolios between 50% and 75% stocks historically produced the highest safe withdrawal rates. Too little equity exposure leaves portfolios unable to generate returns exceeding inflation and withdrawals over long time horizons. Excessive equity exposure increases volatility and sequence risk.
The Rising Equity Glide Path
Contrary to conventional wisdom that equity allocation should decline throughout retirement, research by Wade Pfau and Michael Kitces demonstrates that rising equity glide paths can actually reduce sequence risk.
This counterintuitive strategy starts retirement with lower equity exposure—perhaps 30% to 40%—then systematically increases stock allocation over the first 10 to 15 years, potentially reaching 70% or higher.
The logic: sequence risk is most acute when portfolio balances are highest—at and immediately following retirement. By reducing equity exposure precisely when dollar losses would be largest, then increasing allocation after withdrawals have reduced the portfolio and early returns have been revealed, this approach optimizes exposure to match changing risk profiles.
Pfau and Kitces found that portfolios starting at 30% stocks and rising to 70% over retirement lasted longer in worst-case scenarios than static 60% equity allocations. The rising glide path excels precisely when markets perform poorly early then recover later.
Bond Ladders for Predictable Income
Bond ladders offer an alternative for retirees seeking predictable cash flows without market volatility. A ladder consists of individual bonds with staggered maturity dates, each timed to provide needed income when expenses come due.
For example, a retiree needing $80,000 annually for seven years until Social Security begins at age 70 might purchase seven bonds, each worth approximately $80,000, maturing sequentially from year one through year seven. As each bond matures, the principal funds that year’s expenses.
Individual bonds held to maturity return par value regardless of interim interest rate fluctuations, eliminating mark-to-market volatility. You know precisely what cash flows you’ll receive and when, enabling confident spending decisions.
Dynamic Withdrawal Strategies
Static withdrawal rules—taking a fixed percentage initially then adjusting only for inflation—maximize sequence risk because they ignore changing market conditions. Dynamic withdrawal strategies adjust spending based on portfolio performance, reducing risk substantially.
The “guardrail” approach establishes withdrawal rate bands that trigger spending adjustments. If your current withdrawal rate rises 20% above your initial rate, you reduce spending by 10%. If it falls 20% below the initial rate, you can increase spending by 10%.
These guardrails prevent both overspending when markets decline and excessive underspending when markets thrive. The strategy automatically reduces withdrawals after poor returns—exactly when sequence risk is most acute.
Another approach, the “floor and ceiling” strategy, establishes dollar spending boundaries. Annual spending is capped at the previous year’s amount plus 5% (the ceiling) and floored at the previous year minus 2.5% (the floor). Research by Vanguard and T. Rowe Price shows dynamic strategies can increase terminal portfolio values by 15% to 40% compared to static rules, particularly for retirement cohorts experiencing significant sequence risk.
The Critical Role of Inflation Protection
William Bengen identifies inflation as “the greatest enemy of retirees.” Sequence risk dramatically amplifies when inflation spikes, as withdrawals adjusted for inflation require selling progressively more shares to meet rising dollar needs even as market values decline.
Protection against inflation requires maintaining substantial equity exposure throughout retirement, as stocks historically provide superior inflation-adjusted returns over multi-decade periods. Treasury Inflation-Protected Securities (TIPS) offer explicit inflation indexing for the fixed income portion of portfolios. Avoiding excessive fixed-rate nominal bonds prevents the erosion of purchasing power during inflationary periods.
Practical Steps for Managing Sequence Risk
Based on comprehensive historical analysis and modern research, here’s what works:
Establish realistic withdrawal rates appropriate to starting market valuations and inflation expectations. The universal 4% rule may be too aggressive or unnecessarily conservative depending on your specific circumstances.
Maintain balanced asset allocations, potentially utilizing rising equity glide paths to reduce volatility when portfolio values are highest while preserving growth potential for later years.
Consider dynamic withdrawal strategies that adjust spending based on portfolio performance rather than blindly following static inflation-adjusted amounts. Being flexible—spending a bit less after poor market years and a bit more after strong years—dramatically improves portfolio longevity.
Ensure adequate liquidity through modest cash reserves (3-6 months of expenses) or bond ladders for near-term income needs, while keeping growth-oriented assets fully invested. However, avoid excessive cash holdings that create opportunity cost through permanently lower returns.
Monitor portfolio health through withdrawal rate metrics. Calculate your “current withdrawal rate” annually—next year’s planned dollar withdrawal divided by current portfolio value. Compare this to your initial target rate. Modest deviations during bear markets are normal and typically resolve as markets recover. However, persistent deviations, particularly those driven by sustained high inflation, demand corrective action.
The Bottom Line
The mathematics of sequence risk are unforgiving, but the strategies for managing it are well-established. Those who enter retirement with realistic withdrawal expectations, diversified portfolios, and willingness to adjust spending when conditions warrant can navigate even challenging market environments successfully.
The retirees who struggle are typically those who ignore sequence risk entirely or rigidly adhere to spending plans disconnected from portfolio realities. Your first decade of retirement is too critical to leave to chance.
For investors managing substantial assets—typically $2 million or more—working with experienced advisors who understand these dynamics becomes invaluable. The goal isn’t merely surviving retirement but thriving throughout it: maintaining your desired lifestyle, funding meaningful experiences, and leaving legacies when desired, all while navigating the inevitable market volatility that makes early retirement years so critical to long-term success.
With proper planning and periodic course corrections, you can protect against the sequence risk that has derailed countless retirement plans throughout history. The key is recognizing the threat, implementing appropriate safeguards, and remaining flexible enough to adjust when circumstances demand it.
