60/40 vs all-weather: how the portfolios behave

Why this comparison matters

The 60/40 and the all-weather portfolio are often framed as opposites: the simple legacy mix versus the engineered all-conditions design. That framing obscures what they share. Both are diversification strategies that depend on stocks and bonds not falling at the same time. When 2022 violated that assumption, both struggled, and the more engineered of the two struggled more. Understanding why requires looking at how each one allocates, not at how each one is marketed.

What the 60/40 is

The 60/40 allocates 60% of capital to equities and 40% to bonds, rebalanced periodically. It is a dollar-weighted rule: the split is in money, not in risk. Over the long run a US 60/40 has returned roughly 8.7% annualized nominally since 1928, with stocks supplying growth and bonds supplying ballast. Most calendar years are positive, punctuated by occasional sharp drawdowns such as about 22% in 2008. The logic rests on bonds rising, or at least holding, when equities fall.

What all-weather is

All-weather, popularized by Bridgewater’s Ray Dalio, allocates by risk contribution rather than dollars. It maps assets to four macro environments — rising and falling growth, rising and falling inflation — and aims for each to carry a similar share of portfolio volatility. Because bonds are far less volatile than equities, equalizing risk usually requires leverage on the bond and inflation-hedge sleeves. The promise is steadier returns across conditions, not higher returns.

The key differences

What gets divided. The 60/40 divides dollars; all-weather divides risk. In a 60/40, equities supply roughly 90% of total portfolio volatility despite being only 60% of the money, because stocks are around four to five times more volatile than investment-grade bonds. All-weather flattens that by levering up the calmer assets so each environment contributes comparable risk. This is the mechanical core of risk parity.

The hidden shared assumption. Both rely on negative or low stock-bond correlation. When that correlation flips positive, diversification stops working for either — and leverage turns from a feature into an amplifier. In 2022 the rolling stock-bond correlation rose to roughly +0.65, against a long-run average near −0.20. A US 60/40 fell about 16.1% on the year (Vanguard), while Bridgewater’s All Weather lost around 22%, its worst calendar year on record, exceeding even its −20% in 2008.

Behaviour across the cycle. The 60/40’s path tracks equities with muted swings: a beta near 0.6 to the S&P 500 over recent decades. All-weather’s path depends on its leverage and inflation-hedge sizing, which is why risk parity products that held heavier commodity exposure in 2022 lost less than those that did not. The two designs are not opposites; they are points on the same diversification spectrum, differing mainly in how aggressively they engineer the risk split.

How they behave across regimes

In disinflation with falling or stable real rates — broadly the 2009-2021 backdrop — both designs did well, because the negative stock-bond correlation held and bonds cushioned equity drawdowns. In the 2022 inflation shock, with the Fed lifting policy rates by 525 basis points and real rates rising sharply, stocks and bonds fell together; the 60/40 posted its worst year since the global financial crisis, and all-weather posted its worst year ever, because leverage compounded the losses rather than softening them. The reversal also reset forward expectations: with valuations lower and yields higher, the expected return on a US 60/40 mix rose after 2022, and the strategy rebounded the following year. The switching parameter is the stock-bond correlation itself: when it is negative, both strategies hum; when it turns positive in an inflationary tightening, both falter, and the leveraged one falters more.

The 60/40 and all-weather are not opposing bets; they are the same bet on stock-bond correlation, taken at two different levels of leverage. The broader project lives in comparisons across assets and concepts.

The common confusion

The recurring error is reading “all-weather” literally: assuming a portfolio engineered to survive every climate cannot suffer in any single one. The 2022 record contradicts that reading. The name describes a design intention, not a guarantee. A more accurate way to frame it is that all-weather diversifies across more macro environments than a 60/40, but both still depend on the same correlation assumption underneath — and when that assumption breaks, the engineered version’s leverage works against it. The 60/40 carries this exposure unlevered, so its bad years are painful but bounded by its own asset prices; an all-weather design carries it levered, so a correlation shock can cut deeper. Diversifying across four environments is not the same as being immune to a regime where the correlation engine stalls.

Frequently asked questions

How is the 60/40 different from an all-weather portfolio?

The 60/40 divides capital, fixing 60% in stocks and 40% in bonds; the all-weather divides risk, sizing positions so each macro environment carries roughly equal volatility, which typically requires leverage on lower-volatility assets. A 60/40 ends up with most of its risk in equities, whereas all-weather spreads risk across growth and inflation regimes. Both, however, assume stocks and bonds will not fall together, so the structural difference is one of degree and engineering rather than of underlying dependency.

Why did all-weather lose more than the 60/40 in 2022?

In 2022 the stock-bond correlation turned positive, rising to roughly +0.65 against a long-run average near −0.20, so both asset legs fell at once. A US 60/40 declined about 16.1% on the year. All-weather, which uses leverage to equalize risk across assets, saw those losses amplified rather than cushioned: Bridgewater’s All Weather lost around 22%, its worst calendar year on record. Leverage helps when diversification works and hurts when correlations converge.

Does a 60/40 still make sense after 2022?

Historically the 60/40 has produced positive returns in most calendar years, with a long-run nominal annualized return near 8.7% since 1928, interrupted by occasional sharp drawdowns like 2008 and 2022. Its effectiveness tracks the stock-bond correlation: it diversifies well when that correlation is negative and poorly when it is positive. The data describe a strategy that is rate- and regime-dependent rather than broken, which is a constat, not a recommendation.
