Sequence of Returns Risk

Sequence of Returns Risk refers to the heightened risk faced by investors, particularly those in or near retirement, where the chronological order of investment returns (good or bad) has a disproportionate effect on their portfolio's lifespan when regular withdrawals are being made.

Why it matters

This risk matters immensely for retirees because a series of poor investment returns early in retirement, combined with regular withdrawals, can deplete a portfolio much faster than if those same poor returns occurred later. This specific real-world consequence can lead to running out of money prematurely, forcing drastic lifestyle changes or even outliving one's savings, despite having what seemed like adequate capital initially.

How it works

Sequence of Returns Risk operates by magnifying the impact of market fluctuations when withdrawals are involved. During the accumulation phase, early negative returns are offset by future contributions and subsequent growth. However, during the decumulation (withdrawal) phase, early negative returns force an investor to sell more shares at lower prices to meet withdrawal needs. This phenomenon is often called 'dollar-cost ravaging.' Instead of benefitting from buying more shares when prices are low (dollar-cost averaging), you are forced to sell more shares at a loss, permanently reducing your portfolio's base for future recovery. There isn't a single universal formula, but the calculation involves iteratively adjusting the portfolio balance based on returns and withdrawals: **Portfolio Balance (End of Year) = (Portfolio Balance (Start of Year) * (1 + Annual Return)) - Annual Withdrawal** The cumulative effect of this calculation over multiple years, with varying return sequences, demonstrates the risk.

Example

Two Retirees with Identical Average Returns but Different Sequences

Initial Portfolio (Both)

$1,000,000

Annual Withdrawal (Both)

$40,000 (4%)

Scenario A: Early Negative Returns

Year 1: -10%, Year 2: +15%, Year 3: +5% (Average: 3.33%)

Scenario B: Early Positive Returns

Year 1: +15%, Year 2: +5%, Year 3: -10% (Average: 3.33%)

Portfolio Balance (Scenario A after 3 years)

Starting $1M -> End of Y1: ($1M * 0.9) - $40k = $860k -> End of Y2: ($860k * 1.15) - $40k = $949k -> End of Y3: ($949k * 1.05) - $40k = $956,450

Portfolio Balance (Scenario B after 3 years)

Starting $1M -> End of Y1: ($1M * 1.15) - $40k = $1.11M -> End of Y2: ($1.11M * 1.05) - $40k = $1.1255M -> End of Y3: ($1.1255M * 0.9) - $40k = $972,950

Despite both scenarios having the exact same annual returns and average return over three years, Scenario B (early positive returns) leaves the retiree with a significantly larger portfolio balance of $972,950, compared to Scenario A's $956,450. This demonstrates how early poor returns can critically impair a portfolio's ability to recover and sustain withdrawals, even with subsequent good returns.

Key Takeaways

1

The timing of investment returns, not just the average return, is crucial for portfolio longevity, especially in retirement.

2

Early negative returns during withdrawal phases can disproportionately deplete a portfolio, forcing more assets to be sold at lower prices.

3

Mitigation strategies like dynamic spending, cash buffers, or adjusting asset allocation are essential for managing Sequence of Returns Risk.

While related, Sequence of Returns Risk is distinct from general market volatility. Market volatility refers to the degree of price fluctuations in the market, which can be high or low. Sequence of Returns Risk specifically highlights that the *order* of these volatile (or even stable) returns matters most when you are actively withdrawing funds. A volatile market with bad returns early in retirement is far more damaging than the same volatile market with bad returns occurring later, after your portfolio has had time to grow or reduce its dependency on withdrawals.
