Is the 60/40 Portfolio Dead? What the Historical Data Actually Shows

Step 1: What actually happened in 2022

In 2022, the 60/40 portfolio delivered its worst performance since 1937 and one of its worst in roughly 200 years, according to Morgan Stanley Investment Management's own analysis of the strategy. Stocks and bonds fell together as the Federal Reserve raised interest rates aggressively to fight inflation, which broke the usual pattern where bonds cushion a stock selloff.

That simultaneous decline is exactly why the '60/40 is dead' narrative took hold. Bonds are supposed to zig when stocks zag; in 2022 they zagged together, and a strategy built on that offset looked broken for the first time in most investors' memory.

Step 2: The rebound the headlines skipped

The 60/40 portfolio rebounded sharply in the two years that followed as inflation cooled and interest rates stabilized, per Morgan Stanley's own data on the strategy. Stocks and bonds both posting gains again restored the diversification benefit that briefly disappeared in 2022.

The lesson isn't that 2022 didn't happen, it did, and it hurt. The lesson is that judging a decades-long strategy by its single worst year, then declaring it permanently broken, ignores what happened in the years right after. A strategy built for a full market cycle needs to be judged across a full cycle, not one bad year.

Step 3: Why bonds and stocks fell together in 2022 (and usually don't)

Stocks and bonds normally have a low or negative correlation, which is the entire reason to hold both. 2022 was unusual because the shock hit both asset classes through the same channel: the Fed's rapid rate hikes hurt bond prices directly, since higher rates make existing lower-yield bonds worth less, while also spooking stock valuations, which are sensitive to the discount rate used to value future earnings.

That kind of shared shock is rare but not unprecedented — it is closer to a once-in-a-generation event than the new normal. Most historical downturns, including 2008 and 2020, saw bonds hold up or gain while stocks fell, which is the diversification benefit working as intended.

Step 4: Is 60/40 still a reasonable default?

For an investor without a strong view on markets, 60/40 remains a reasonable, evidence-based starting point precisely because it doesn't require predicting the next crisis. Our stocks vs bonds comparison covers the classic age-based rule, 110 minus your age in stocks, that 60/40 approximates for a mid-career investor.

That said, 'reasonable default' is not the same as 'right for everyone.' Someone decades from retirement with a high risk tolerance may prefer a more stock-heavy mix like 70/30 or 80/20 for higher expected growth. Someone already retired and drawing down the portfolio may want more bonds, not fewer, for stability. Use the 60/40 portfolio calculator to see the expected return and risk for your own numbers, and the asset allocation calculator to test other splits.

Step 5: What to actually do with this information

Don't abandon a long-term allocation because of one bad year, and don't assume 2022 can't happen again either. Both are overreactions. A more useful response is to check that your bond allocation matches your actual time horizon, since shorter-duration bonds hold up better when rates rise sharply, and that your stock-to-bond mix still matches how much risk you can actually tolerate, not how it felt to watch the account in late 2022.

If your answer is that 60/40 still fits your time horizon and risk tolerance, the historical data supports keeping it. If your time horizon has genuinely changed, that's a real reason to adjust the mix, the 2022 headlines by themselves are not.
