Sequence of Returns Risk: Why the First Decade of Retirement Matters Most
Key Takeaways
- The Danger Zone: The 5 years before and after retirement (the “Red Zone”) are when your portfolio is most vulnerable to market crashes.
- Reverse Compounding: Withdrawing money during a downturn permanently shrinks your capital base, making recovery difficult.
- Cash is King: Holding a 1-2 year cash buffer can prevent you from selling stocks at a loss when the market dips.
During the saving years, volatility is largely irrelevant—downturns simply create opportunities to buy assets at lower prices. But once withdrawals begin, the sequence of returns becomes more important than the average return itself. Early negative returns, combined with ongoing withdrawals, can structurally compromise the long-term sustainability of a retirement portfolio.
| Variable | Accumulation Phase | Withdrawal Phase |
|---|---|---|
| Market Declines | Opportunity to buy more | Forces selling at a loss |
| Volatility Impact | Minimal long-term impact | Can shorten portfolio lifespan |
| Primary Risk | Insufficient growth | Portfolio depletion |
| Key Mechanic | Dollar Cost Averaging | Reverse Dollar Cost Averaging |
The Structural Problem of Early Losses
Two portfolios can share the same long-term average return, yet their outcomes may diverge dramatically depending on when downturns occur. When early negative years coincide with withdrawals, the compounding base shrinks permanently—creating a structural drag that later bull markets cannot fully offset.

Mitigation Approaches (Institutional Framework)
Keep 1–2 years of spending needs in cash or short-term bonds. This ensures you never have to sell stocks to pay bills during a crash.
Instead of withdrawing a fixed amount, be flexible. Skipping an inflation adjustment or withdrawing slightly less during bear markets can save your portfolio.
