Sequence of Returns Risk
The risk that experiencing poor returns early in retirement can deplete your portfolio faster, even with the same average returns. Learn why retirement timing matters.
📝 Definition
What is Sequence of Returns Risk?
Sequence of Returns Risk (often called Sequence Risk) is the danger that the timing of your investment returns—the order in which they occur—will significantly damage your portfolio's longevity. While it doesn't matter much during the accumulation phase (when you are adding money), it becomes critical during the withdrawal phase (retirement). If you experience a series of negative returns in the first few years of retirement while simultaneously withdrawing money for living expenses, your portfolio can be depleted so quickly that it may never recover, even if high returns occur later in your life.
In Simple Terms
A Simple Metaphor: The Gas Tank and the Desert
Imagine you are driving across a vast desert with a gas tank that leaks a fixed amount every day (your living expenses). If you hit a "gas station" (market gains) early in the trip, your tank stays full and you can easily make it across. However, if the first half of the desert has no gas stations (market losses), you might run out of fuel halfway through. Even if there are massive gas stations in the second half of the desert, they don't matter because you've already stalled out. Sequence risk is the bad luck of hitting the "dry patch" right when you start your journey. It proves that in retirement, averages don't tell the whole story; the start of your retirement is much more important than the end.
Example
A Tale of Two Retirees
Imagine Retiree A and Retiree B both retire with $1 million and withdraw $50,000 annually. Both experience an average annual return of 7% over 20 years. However, Retiree A experiences negative returns in the first 3 years, while Retiree B experiences positive returns in the first 3 years. Because Retiree A was forced to sell shares at rock-bottom prices to pay for their $50,000 living expenses, they ran out of money in year 15. Meanwhile, Retiree B, whose portfolio grew early on, ended year 20 with over $2 million. This massive difference was caused solely by the sequence of their returns, not their long-term average.
💡 Practical Tips
- 1<strong>Build a 'Cash Buffer':</strong> Keep 2-3 years of living expenses in cash or short-term bonds. If the market crashes early in your retirement, spend the cash instead of selling your stocks at a loss.
- 2<strong>Use Dividend Income:</strong> Dividends provide cash flow without requiring you to sell shares. This effectively bypasses sequence risk because your principal (the number of shares you own) remains intact even when prices are down.
- 3<strong>Dynamic Spending:</strong> Be prepared to reduce your withdrawal rate (e.g., from 4% to 3%) during the first few years if the market is in a severe downturn.
- 4<strong>Asset Allocation 'Glide Path':</strong> Reduce your stock exposure as you approach retirement to minimize the impact of a crash, then slowly increase it again later in retirement (a 'Rising Equity Glide Path').
⚠️ Common Mistakes
Relying Solely on 'Average' Returns
The most dangerous mistake is assuming that because the stock market has returned 10% on average historically, you are safe withdrawing 4% or 5% regardless of timing. In retirement, volatility is much more dangerous than in your 30s. A single 'lost decade' at the start of your retirement can destroy a plan that looked perfect on paper. You must plan for the worst-case scenario (a bear market in Year 1) rather than the average scenario.
