Passive investing has long been a popular and accessible investment strategy, and for good reason. Low fees, broad market exposure, and decades of strong equity returns have made index-based strategies the default choice for millions of investors building portfolios on the premise of long-term accumulation.
But the same qualities that make passive investments compelling can become liabilities for those in or approaching retirement. For this population, the conversation needs to evolve.
The core value proposition of passive investing is straightforward: accept 100% of the downside in exchange for 100% of the upside, at the lowest possible cost. Think of it like an airplane on autopilot. When the skies are clear, it works beautifully. But when storms roll in, you want a human override. The last decade and a half has largely been blue skies, the near-perfect environment to make passive strategies look as good as they possibly can. Retirement is where the weather can change.
That trade-off works well during accumulation, when investors have time on their side and a regular paycheck buffering the psychological weight of market declines. Retirement changes the equation fundamentally. Retirees no longer have earned income to offset losses, and they are systematically withdrawing from savings, replacing a paycheck with a drawdown. The timing of market declines relative to those withdrawals matters enormously, and many retirees don’t have the luxury of withdrawing only when markets are up.
This is sequence of returns risk. The impact of bear markets doesn’t stem solely from their occurrence; it also depends on when they occur in an investor’s journey. A major decline early in retirement, when savings are at their peak, can force selling at depressed prices, lock in losses, and permanently diminish the asset base needed to fund expenses across two to three decades. This is not a remote scenario. Based on historical patterns, a retiree with a 15 to 20-year horizon should expect to live through three or four major market declines. Beyond the time horizon question, there is a more immediate reality: asking a retiree to endure 100% of the downside on a valuation- and quality-agnostic basis is more than most retired investors are emotionally – and often financially – capable of handling.
The challenge is compounded by the fact that market declines rarely happen in isolation. When equity markets fall sharply, home values often follow. Adult children may lose jobs. More family members may need financial support. The consequences are compounded, and advisors are prone to underestimating this multiplier effect when counseling clients through volatility.
There is also the question of what passive investing means in the current environment. Equity index funds are, by design, valuation-agnostic and quality-agnostic. They hold whatever is in the index, regardless of price or balance sheet strength. Over the past decade and a half, that approach has been handsomely rewarded, partly because a narrow group of mega-cap technology companies accounted for a disproportionate share of index gains. When seven stocks are responsible for a large percentage of a 500-stock index’s returns, it becomes very difficult for any active manager – whose mandate includes diversification – to compete. Those conditions – low interest rates, expanding multiples, a market propped up by a handful of names – are not guaranteed to persist.
Equity valuations are historically elevated today, and credit spreads are tight. Valuation is an unreliable short-term timing tool, but a reasonably reliable indicator of longer-term return expectations. Based on current starting points, the next decade will likely deliver more muted equity returns with deeper drawdowns than the previous one. This is a substantially different environment for retirement portfolio construction.
That isn’t to say passive investing no longer has a place. Core index exposure remains a sensible, cost-efficient component of most portfolios. But these conditions should push advisors and investors to pair passive investments with active strategies specifically chosen to dampen volatility, limit large losses, and provide return streams that don’t depend on favorable equity markets. The case for passive investing is far more compelling for someone in their 20s with decades of runway than for someone in their 70s managing withdrawals in real time. For retirees, the common denominator across active managers should be a clear priority on large-loss avoidance—not benchmark-beating performance, but a smoother ride through market cycles.
That distinction matters more than the industry typically acknowledges. Consider two portfolios: one returns 12% annually but requires riding through two 35% drawdowns and years of recovery; another returns 10% with shallower declines that allow the investor to stay the course. Ten percent is not necessarily less than twelve percent—it can simply be different, and for many retirees, it may actually be better.
Most retirees aren’t asking whether they beat a benchmark. They’re asking a simpler question: Am I going to be okay? Can I keep withdrawing the same amount each month and continue to live the life I worked for? The goal of a retirement portfolio is not to outperform an index. It is to generate sufficient, sustainable returns to fund a lifestyle over decades without asking investors to act in ways they’re incapable of under pressure.
One practical tool that supports this is a liquidity buffer, typically one to two years of living expenses in cash or cash equivalents. This insulates retirees from being forced to sell into a declining market to meet monthly expenses and improves their ability to stay invested through difficult cycles.
Building an optimized retirement portfolio today means carefully considering diversification beyond traditional stock-and-bond splits. A well-constructed portfolio should include equities, fixed income, alternatives, and, where appropriate, private vehicles—each selected for its role in managing downside risk and generating returns not fully correlated with equity market performance. For investors who insist on passive-only exposure, the burden of risk mitigation falls entirely on the advisor, who must manage volatility through portfolio construction, client education, and behavioral coaching. That is a significant responsibility to carry alone, and advisors who choose this path should be clear-eyed about what they are taking on.
The goal is not to abandon passive investments, but to strengthen them through thoughtfully paired active strategies that give investors the best chance of funding the retirement they planned for.
