What Is a Sequence of Returns Risk?

Sequence of returns risk is one of the most significant — and least understood — threats to retirement security. Unlike accumulation, where the order of returns doesn't matter (your ending balance is the same regardless), the withdrawal phase is extremely sensitive to early losses.

A retiree who experiences a major market downturn in the first 3-5 years of retirement may never recover, even if markets subsequently perform well — because they've sold shares at depressed prices to fund withdrawals, leaving fewer shares to participate in the recovery. This is why asset allocation, withdrawal strategy, and income planning are so critical in the years immediately before and after retirement.

The math: Consider two scenarios with the same 7% average annual return over 20 years:

Scenario A (good returns first): +20%, +15%, +10%, then average returns. With $500,000 and $25,000 annual withdrawals, the portfolio ends at approximately $850,000.

Scenario B (bad returns first): -20%, -15%, -10%, then above-average returns. Same average return, same withdrawals. The portfolio ends at approximately $200,000 — or may be depleted entirely.

Why it happens: When you withdraw from a declining portfolio, you're selling more shares to generate the same dollar amount. Those shares are no longer available to recover when markets rebound. This creates a permanent drag on portfolio value.

The danger zone: The 5 years before and 5 years after retirement are the highest-risk period for sequence of returns. This window is often called the "retirement risk zone" or "fragile decade."

Mitigation strategies: 1. Cash/bond buffer: Hold 2-3 years of expenses in stable assets to avoid selling stocks during downturns 2. Flexible withdrawal rates: Reduce withdrawals during down markets (spend less or draw from stable assets) 3. Bucket strategy: Segment your portfolio into time-based buckets with different risk profiles 4. Guaranteed income: Use Social Security, pensions, or annuities to cover essential expenses — reducing the amount you need to withdraw from volatile investments 5. Dynamic asset allocation: Gradually reduce equity exposure entering retirement, then potentially increase it later (the "bond tent" or "rising equity glide path" strategy)

Arizona retirees can leverage several state-specific advantages to mitigate sequence risk: Social Security income (untaxed in Arizona) provides a stable income floor, Arizona's low cost of living (especially outside Scottsdale) reduces required withdrawal rates, and the state's 2.5% flat tax means more after-tax income from guaranteed sources like pensions and annuities.
