In the current record-breaking inflation and rising interest rate environment across all major markets, stocks and bonds have declined in values simultaneously.
As a result, many analysts and commentators have speculated on the death of the 60% stock/40% bond portfolios. But we have seen this before. Based on Vanguard’s research, balanced portfolios have proved critics wrong before and we believe they will prove them wrong, again. Here are five reasons why a 60% stock/40% bond portfolio is NOT dead.
Reason 1: Stock-bonds simultaneous decline is not long lasting
A simultaneous decline or positive correlation in stocks and bonds has typically not lasted long and the phenomenon has never occurred over a three-year span. A similar trend is visible on a 60/40 (stocks/bonds) portfolio.
Drawdowns in 60/40 portfolios have occurred more regularly than simultaneous declines in stocks and bonds; however, their frequency of occurrence also declines over longer periods. More regular occurrence is due to the far-higher volatility of stocks and their greater weight in that asset mix. One-month total returns were negative one-third of the time over the last 46 years. The one-year returns of such portfolios were negative about 14% of the time, or once every seven years or so, on average.

Stock-Bonds correlation remains negative in the long term
Our study of 60-day and 24-month stock-bonds rolling correlations from 1992 to 2022 suggests that over a long-term, correlation between stocks and bonds remains negative. That said, long-term inflation is one of the determinants of correlation between the two asset classes

Reason 2: Long-term expected returns from 60/40 are still achievable
The goal of a 60/40 portfolio is to achieve long-term annualized returns of roughly 7%. This is meant to be achieved over time and on average, and not every year. The annualized return of 60% U.S. stock and 40% U.S. bond portfolio from January 1, 1926, through December 31, 2021, was 8.8%.1 On a forward-looking basis, Vanguard Capital Markets Model (VCMM) projects the long-term average return to be around 7% for the 60/40 portfolio, over the next 10 years. Market volatility means diversified portfolio returns will always remain uneven, comprising periods of higher or lower: and, yes, even negative returns.
The average return we expect can still be achieved if periods of negative returns (like this year) follow periods of high returns. During the three previous years (2019–2021), a 60/40 portfolio delivered an annualized 14.3% return, so losses of up to –12% for all of 2022 would just bring the four-year annualized return to 7%, back in line with historical norms.
Our forecast points to improved stocks and bond returns
On the flip side, the math of average returns suggests that periods of negative returns must be followed by years with higher-than-average returns. Indeed, with the painful market adjustments year-to-date, the return outlook for the 60/40 portfolio has improved, not declined. Driven by lower equity valuations and higher bond yields, our 10-year annualized average return outlook for the 60/40 is now higher by 1.3 percentage points than before the recent market adjustment.
Reason 3: Selling bonds in a rising rate environment is like selling low and buying high (in short, don’t try to time the market)
Chasing performance and reacting to headlines are doomed to fail as a timing strategy every time, since it amounts to buying high and selling low. Far from abandoning balanced portfolios, investors should keep their investment programs on track, adding to them in a disciplined way over time. Continue Reading…
