What is Sequence of Returns Risk?

Sequence of returns risk is the danger of retiring just before a market downturn—early losses can cripple a portfolio even if average returns look fine. This risk is particularly acute for retirees who are actively withdrawing capital from their portfolios to cover living expenses. If a portfolio experiences a severe market downturn early in retirement, the retiree is forced to liquidate depreciated assets, locking in paper losses and permanently reducing the portfolio's recovery potential.

Even if two portfolios experience the exact same average annual return over a 30-year retirement, the portfolio that suffers losses at the beginning will deplete much faster than the portfolio that experiences losses at the end. This concept is explored in investor education materials from the SEC and historical studies published in the Social Security Bulletin.

Retirees manage sequence of returns risk through asset allocation strategies. Common approaches include maintaining a cash buffer (1-3 years of living expenses in cash or cash equivalents) to avoid selling equities during a bear market, utilizing a dynamic withdrawal strategy that reduces spending during market downturns, or allocating a portion of assets to guaranteed income streams like annuities.
