The late John C. Bogle, who died in January 2019, built a legacy around a simple but powerful idea: investors do not need to be market experts to succeed. They simply need to minimize costs, stay disciplined, and let compounding do the heavy lifting. As the founder of The Vanguard Group, which now manages more than $10 trillion in assets, Bogle helped popularize low-cost index investing. His philosophy continues to guide millions of investors today, especially those nearing retirement. Investors who follow Bogle’s principles of low-cost index funds, diversification, and disciplined long-term investing are affectionately called Bogleheads.
At its core, Bogle’s counsel emphasized maintaining an appropriate asset allocation and avoiding excessive risk. That may not sound groundbreaking, but a surprising number of retirees shoulder more risk than they can afford. After a multi-year bull run, markets entered a period of heightened volatility in 2026. Corrections at the individual stock level have tested investor resolve even as major indexes have held up.
Both the Vanguard S&P 500 ETF (NYSEARCA:VOO) and the Vanguard Total Stock Market ETF (NYSEARCA:VTI) have weathered periods of turbulence this year, causing some soon-to-be-retired Bogle followers to wonder whether their equity allocation runs too hot. How much equity exposure is too much risk for a retiree? Can you take excessive risk even in the supposedly safer world of bonds?
Let’s examine these questions with Bogle’s cautious but optimistic beliefs in mind:
The stock market may deliver lower returns going forward. Accept that reality
Goldman Sachs (NYSE:GS | GS Price Prediction | GS Price Prediction) opened 2026 projecting the S&P 500 would produce a 12% total return for the year, down from 18% in 2025 and 25% in 2024. By late May, Goldman had revised its year-end S&P 500 target upward to 8,000 from 7,600, projecting approximately a 6% return from then-current levels. The firm expects S&P 500 earnings per share to grow 24% in 2026, with AI infrastructure beneficiaries accounting for roughly half of that earnings growth. That upward revision reflects a sharp market rally of about 13% from late March lows, not a change in the underlying message for retirees: returns are moderating compared to the blockbuster gains of 2023 and 2024.
Chasing above-average results means accepting above-average risk. A heavy bet on concentrated tech positions might outpace the S&P 500 over the next decade, but if that trade sours more severely than the broader market, you could end up trailing even a modest benchmark. Unless you have decades remaining in your investment timeline, settling for market returns at market risk makes far more sense than reaching for excess gains. Elevated valuations leave little margin for error, particularly for investors who cannot afford to wait out a prolonged recovery.
Bonds carry risk, too
Retirees should aim for an asset allocation that matches their risk tolerance. The classic 60/40 or 40/60 stock-to-bond splits remain popular starting points, though the right mix varies by individual. Either way, bonds are not foolproof safe havens. The 2022 stock and bond market selloff was a stark reminder: both asset classes declined together for the first time since 1977, driven by the Federal Reserve’s aggressive rate-hiking campaign. Stocks and bonds have historically moved in opposite directions, providing genuine diversification benefits, but they can and do fall in tandem under inflationary conditions.
Retirees must understand the inherent risk in fixed income. Some bonds offer greater safety than others, and safer bonds typically deliver lower yields. Retirees who chase yield in the bond market may believe they are capturing better returns in a supposedly conservative asset class. In practice, though, higher-yielding bonds carry significantly more credit and duration risk, and they can behave much like equities during downturns, defeating the entire purpose of holding them.
Bogle emphasized keeping an appropriate asset allocation and avoiding excessive risk, particularly in retirement. For retirees seeking to follow that advice, sticking with a low-cost basket of high-quality bonds makes the most sense. The Vanguard Total Bond Market ETF (NASDAQ:BND) is a widely used option as a core fixed-income holding. The goal is to keep fees low and the investment plan as simple as possible, two pillars of the Bogle philosophy.
The bottom line
Bogle’s philosophy tells us that investors nearing retirement must stop accepting undue risk in pursuit of better returns. Risking a comfortable retirement for the chance at a great one makes no sense if it means potentially working several more years. If market returns moderate in the years ahead, the answer is to accept the returns that come with an appropriate level of risk and adjust the retirement plan accordingly. Save more if needed, or work a bit longer if the numbers demand it, but keep your nest egg positioned for sustainability rather than speculation.
Editor’s note: This article was updated to reflect Goldman Sachs’s revised May 2026 S&P 500 year-end target of 8,000 and updated earnings growth forecast of 24% for 2026, and Vanguard’s current assets under management of more than $10 trillion. The 2022 stock-bond correlation breakdown is attributed to the Federal Reserve’s rate-hiking campaign, consistent with Vanguard’s published research.
