The Rebirth of the 60/40 Portfolio Has Been Greatly Exaggerated

The math isn’t adding up for the return of the 60/40 portfolio.

For decades, a rule of thumb advisors used to create a “traditional” portfolio for clients was an allocation of 60% to equities and 40% to bonds. The thinking was that this was the safest bet for investors, with the fixed income component providing some stability in the event that equity markets fall in value. Throw a bunch of index funds into the mix, advisors have argued, and the portfolio becomes even safer, since you are not picking individual stocks.

Any other assets get short shrift. Indeed, alternative investments, according to 60/40 proponents, are to be avoided at all costs, because of the so-called illiquidity risk.

So, how has that worked out over the past few years? Not well. During the past three and a half years, 60/40 portfolios have returned just 2% annually, according to Barron’s. Worse, in the two weeks following President Trump’s announcement of his tariffs plan, the subsequent market volatility led to both the S&P 500 and the Bloomberg Aggregate Bond Index — the latter being the key benchmark for fixed income — both losing value.

In theory, proponents of the 60/40 portfolio argue that stocks and bonds are supposed to be negatively correlated, providing a natural hedge for the portfolio. However, this has not always held true, especially in recent years. In 2022, both the S&P 500 Index and the Bloomberg U.S. Aggregate Bond Index fell in the same year for the first time in history.

Given the strong public market performance of 2023 and 2024, some market strategists have posited that 2022 was nothing more than a fluke. However, the jury is still out on that, and investors need to take note. For one thing, rather than being risky, alternative assets were a safe haven in the bloodbath of 2022, reporting a positive return, while the vast majority of other asset classes were in the red. The illiquidity of these opportunities provided the kind of wealth protection that 60/40 portfolios just couldn’t deliver.
