For the past three years, the stock market has been nothing short of a juggernaut. Investors watching their brokerage accounts tick upward have enjoyed a rare, exhilarating run, with the S&P 500 posting solid double-digit gains throughout 2023, 2024, and 2025. While world events have occasionally rattled investor confidence, the overarching trend has been a consistent, robust climb that has left many portfolios at all-time highs.
However, this period of sustained prosperity brings with it a subtle, often dangerous psychological trap. For those currently enjoying the fruits of a long-term investment strategy—particularly those approaching or already in retirement—the current market environment poses a fundamental question: Is your portfolio positioned for the future, or are you simply riding the momentum of the past?
The Mirage of Infinite Growth: Understanding Recency Bias
At the heart of the current investor dilemma is a psychological phenomenon known as "recency bias." This cognitive shortcut leads individuals to place disproportionate weight on recent events while discounting historical context. When the market delivers three consecutive years of double-digit returns, the human brain is hard-wired to assume that the trend is a permanent state of affairs rather than a cyclical occurrence.
History, however, tells a different story. According to long-term return data compiled by institutions such as the NYU Stern School of Business, the stock market has rarely sustained such prolonged periods of high growth without experiencing intermittent corrections. Since 1926, instances of three consecutive years of double-digit gains are statistically rare, and they are almost invariably followed by years of stagnation or decline.
When investors fall under the spell of recency bias, they often become complacent. They assume that if they haven’t suffered a major loss in three years, they aren’t susceptible to one in the fourth. This false sense of security can lead to a dangerous disconnect between an investor’s actual risk exposure and their stated risk tolerance.
Risk Tolerance vs. Risk Capacity: A Critical Distinction
To navigate the transition into retirement, investors must distinguish between two vital concepts: risk tolerance and risk capacity.
Risk tolerance is a subjective, psychological measure—it is your emotional ability to sleep at night while watching the market fluctuate. Many investors discover their risk tolerance is much lower than they anticipated only after their portfolio value has dropped significantly.
Risk capacity, by contrast, is an objective, mathematical reality. It represents the actual ability of your financial plan to withstand a market downturn. A thirty-year-old investor has a high risk capacity because they have decades to recover from a 20% market drop. A retiree, however, has a significantly diminished risk capacity. If you are drawing down your savings to cover living expenses during a bear market, you are selling assets at a depressed value, which can lead to a permanent depletion of capital that is mathematically impossible to recover from.
The "Fragile Decade" and Sequence of Returns Risk
The importance of risk capacity is amplified by a phenomenon known as "sequence of returns risk." This is the danger that a major market downturn occurs during the years immediately preceding or following your retirement date. Financial planners often refer to the five years before and the five years after retirement as the "fragile decade."
During this window, the timing of market losses is just as important as the magnitude of those losses. If your portfolio loses 20% in the year you retire, and you are forced to withdraw funds to pay for your lifestyle, you are essentially compounding your losses. You are not only losing the principal, but you are also losing the potential for that money to recover during the next bull market. This is the primary reason why experts suggest that as you reach the five-year countdown to retirement, you must pivot from an "accumulation" mindset to a "preservation" mindset.
Strategic Re-evaluation: Are You Playing for the Right Stakes?
When managing wealth, it is helpful to use a simple stress-test question to gauge your current position: If your portfolio grew by another $100,000 this year, would it meaningfully change your lifestyle?
For the vast majority of investors, the answer is no. Their current standard of living is already met. The follow-up question is far more telling: If the market declined and that same $100,000 vanished, would it affect your confidence, your long-term retirement plans, or your peace of mind?
For most, the answer is an emphatic yes. This reveals an asymmetrical relationship with money: the pain of a loss is often felt much more acutely than the joy of an equivalent gain. If you have already "won the game"—meaning you have successfully saved enough to sustain your lifestyle—why continue to take the same level of risk that got you there?
Avoiding the All-or-Nothing Fallacy
Re-evaluating your risk does not mean exiting the market entirely. Doing so introduces a new, equally dangerous risk: inflation. If you move all your assets into cash, CDs, or ultra-conservative bonds, you may find that your purchasing power is eroded over a 20- or 30-year retirement.
The goal is not to eliminate risk, but to optimize it. A well-constructed retirement portfolio should maintain a portion of its assets in growth-oriented investments to outpace inflation, while simultaneously insulating the portion of the portfolio earmarked for near-term spending from market volatility.
Implications for the Modern Investor
As we look toward the remainder of the decade, the primary takeaway for those nearing retirement is that the market does not owe us a fourth year of double-digit returns. The recent performance of the S&P 500 should be viewed as a signal to review, not to rejoice.
- Assess Your Time Horizon: If you are within five years of retirement, your portfolio needs to look fundamentally different than it did when you were ten years out.
- Quantify Your Needs: Determine exactly how much of your portfolio is needed for essential expenses over the next 3–5 years. This "bucket" should be protected from market volatility.
- Stress Test Your Plan: Use historical data or professional software to see how your portfolio would perform during a "lost decade" or a major recession.
- Rebalance Ruthlessly: If the recent bull market has caused your stock allocation to swell beyond your comfort level, use this period of high valuation to rebalance back to your target allocation.
Conclusion: A New Mindset for a New Stage
The transition from a working professional to a retiree is the most significant financial event of a person’s life. It is the moment when the "accumulation phase" ends and the "distribution phase" begins. While the recent bull market has been a gift, it is also a timely reminder that market cycles are inevitable.
If you have spent your career taking on risks to build your nest egg, you have succeeded. But the strategies that lead to success in building wealth are not necessarily the same strategies required to sustain it. By moving away from the hypnotic influence of recent gains and focusing on a disciplined, risk-adjusted approach, investors can ensure that their retirement is defined by security and peace of mind, rather than by the unpredictable swings of the stock market.
