Stocks vs Bonds in Early Retirement: The Right Allocation

Asset allocation in early retirement is not "set and forget." The conventional wisdom of increasing bonds as you age (the "glide path" of target-date funds) is increasingly questioned for early retirees who have 40–50 year time horizons. Research by Wade Pfau and other retirement income researchers suggests that for long retirements, a portfolio heavy in stocks (70–80%) maintains higher sustainable withdrawal rates than a conservative 60/40 portfolio.

60/40 portfolio for retirement was the conventional wisdom — 60% stocks, 40% bonds. Historically, 60/40 had lower volatility than 100% stocks with surprisingly similar long-term returns. For a 30-year traditional retirement, it works well. For a 40–50 year early retirement, the lower expected return of bonds creates a drag that reduces the maximum sustainable withdrawal rate. The historical sweet spot for long retirements has been 70–80% stocks.

The "rising equity glide path" (Michael Kitces/Wade Pfau research): instead of the traditional declining equity approach (more bonds as you age), start retirement with a conservative 40–50% stock allocation and increase stocks to 60–70% over the first decade. This counterintuitive approach protects against a market crash in the critical early retirement years while allowing equity growth to power the portfolio's long-term survival.

Sequence risk — the risk of a major market decline in your first 5 years of retirement — is the existential threat to early retirement portfolios. Bonds, cash, and alternative assets serve as a "buffer" when stocks are down, allowing you to draw from non-stock sources and avoid selling equities at depressed prices. The 1–2 year cash buffer strategy, combined with 10–20% bonds for additional cushion, manages sequence risk without overly sacrificing long-term growth.
