What an All-Weather Portfolio Tries to Do

An all-weather portfolio tries to hold up across different economic conditions by balancing how much risk each part contributes, not how many dollars go into each part. The approach comes from Bridgewater Associates, and the mixes sold as "all-weather" today are often simplified copies that do not balance risk at all. None of them removes the chance of a large loss.

Key takeaways

• Bridgewater's All Weather, which emerged in its full form in 1996, splits risk across four environments: growth and inflation, each rising or falling against expectations.
• Equal dollars are not equal risk. In the hypothetical example below, a 60/40 stock-bond mix takes about 90% of its risk from stocks.
• In calendar 2022 the S&P 500 returned -18.04% and the 10-year Treasury -17.83%, so a 60/40 mix lost about 18%. Bonds had stopped offsetting stocks.
• The sign of the stock-bond relationship depends on the inflation environment, so any all-weather design carries that regime risk.

Where the idea comes from

Bridgewater's own history page, The All Weather Story (dated January 2012 and based on interviews with the people who built the strategy), says the fully formed All Weather emerged in 1996 and was first created for Ray Dalio's trust assets. It describes the strategy as built on growth and inflation, each of which can come in above or below what markets expected. That gives four environments: rising growth, falling growth, rising inflation and falling inflation.

The design principle is stated plainly on that page: put equal risk on each scenario to achieve balance. The page explains that stocks and bonds can offset each other in growth shocks, and that long-duration bonds, or futures equivalents, were used so the bond side carried roughly as much risk as the stocks. Bridgewater also describes the approach as passive, meaning it does not rely on forecasting which environment comes next.

Bridgewater calls leverage an implementation tool. Leverage here means borrowing, or using futures, to give lower-risk holdings such as bonds a larger influence on the total. That is how institutional versions make a bond holding matter as much as a stock holding. The general name for weighting by risk contribution instead of dollars is risk parity, and the same Bridgewater page presents All Weather as the foundation of that movement.

Three portfolios with similar names

Retail articles often use "all-weather" for fixed-percentage mixes. These share the four-environment logic but differ in how they get there.

Unlike Bridgewater's institutional version, the Robbins mix uses no leverage. Its large weight in long-term Treasuries, which swing more with interest rates than shorter bonds, gives the bond side more influence per dollar. The Permanent Portfolio predates this vocabulary and pairs each asset with one of four states: stocks with prosperity, cash with recession, gold with inflation and long-term bonds with deflation. Both are fixed dollar weights that do not adjust as volatilities and correlations change, which is the next section's subject.

Risk contributions in a 60/40 mix

A portfolio's risk is not split in proportion to its dollars. An asset's risk contribution is its weight times how much it moves with the whole portfolio, divided by total variance.

RC_i = w_i × (Σw)_i / σp²
σp² = wᵀ Σ w
w_i = weight of asset i; Σ = covariance matrix (volatilities and correlations); Σ RC_i = 100%

Illustrative example. These volatilities and correlations are round assumptions chosen for the demonstration, not measured data and not forecasts.

Computed in Python from those inputs, three weightings come out as follows.

Two lessons follow from the numbers. First, 60/40 is a stock portfolio in risk terms: 60% of the dollars produce about 90% of the risk. Even with the stock-bond correlation raised to 0.5, stocks still supply 85.7% of the risk in this setup. Second, equal dollars across four assets is also unbalanced here, because the most volatile asset, commodities, supplies 40%. Equal risk requires a bond weight of about half the portfolio.

The equal-risk mix has 6.6% volatility against 10.4% for 60/40. Multiplying every weight by about 1.57 would match the 60/40 volatility, which requires total exposure of 157% of the capital. This is the kind of leverage Bridgewater calls an implementation tool. The calculation ignores borrowing costs, margin requirements and the chance that these assumptions are wrong.

What 2022 did to stocks and bonds

The bond-heavy design relies on bonds rising or holding steady when stocks fall. Calendar 2022 broke that. The table uses the annual return series published by Aswath Damodaran of NYU Stern, from a version last updated January 5, 2026.

The last row is 0.6 × -18.04% + 0.4 × -17.83%, with weights set at the start of the year, no rebalancing and no fees. The methodology notes in Damodaran's data spreadsheet explain that the Treasury figure is a total return: the year's coupon plus the price change from repricing a bond with a constant 10-year maturity at the new yield. On that basis, the bond leg lost almost as much as stocks.

A Federal Reserve note by Canlin Li and Emre Yoldas, Government Bonds' Safe-Haven Property and Inflationary Pressures (October 16, 2026), measures the correlation between daily stock returns and daily changes in 10-year government bond yields, using data from January 1990 to July 2026. A positive value means bonds hedged stocks, because yields fell when stocks fell.

The authors link good hedging to periods when inflation was near target and expectations were anchored, so central banks could ease when stocks fell. When inflation ran above target, stocks and bonds could fall together. This is why a single correlation estimate, such as the 0.2 used above, is a snapshot and not a constant.

Inflation-sensitive assets

Bridgewater's four-environment framing explains why these portfolios add something beyond stocks and nominal bonds. The inflation slot is usually filled with gold, commodities, inflation-linked bonds, or a mix; Bridgewater's history page says inflation-linked bonds play an important role in its own version.

Each has a different failure mode. Gold returned 0.55% in 2022 in Damodaran's data, a roughly flat year that softened a mixed portfolio's loss but did not offset it. Commodity funds depend on the futures they hold, and a broad basket behaves differently from an energy-heavy one. Treasury Inflation-Protected Securities adjust principal with the Consumer Price Index, but TreasuryDirect notes the principal can fall as well as rise, with the original principal protected at maturity. Their market prices still move with real yields along the way.

Implementation and rebalancing

Three practical points decide whether a mix behaves like its design.

• Bond duration. Long-term Treasuries carry far more interest-rate sensitivity than intermediate ones. Two portfolios that both say "40% bonds" can have very different risk, which is why risk contributions matter more than labels.
• Drift. After a stock decline, bonds grow as a share of the portfolio, and the reverse after a rally. Without rebalancing, the mix drifts toward whatever did best, and the intended balance disappears. To see what trades a given drift requires, use the rebalancing calculator.
• Rules you can follow. A calendar schedule and a drift threshold both work; Browne's Permanent Portfolio uses a threshold, rebalancing when a part strays well off target. The better rule is the one the investor will actually apply during a drawdown.

Frequently asked questions

Does equal dollars mean equal risk?

No. In the example above, a 25% weight in each of four assets gave stocks 30.8%, bonds 4.2%, gold 24.8% and commodities 40.2% of the risk. Risk follows volatility and correlation, not the dollar amount.

Does an all-weather portfolio need leverage?

Bridgewater describes leverage as an implementation tool, not a requirement of the idea. An unlevered equal-risk mix is simply a lower-risk portfolio, 6.6% volatility in the example against 10.4% for 60/40. Matching the 60/40 risk would take about 157% exposure, along with borrowing costs and margin requirements.

Will stocks and bonds keep falling together?

The Federal Reserve note attributes the post-2021 weakness in bond hedging mainly to the mix of shocks, including persistent pandemic-era inflation and supply shocks that arrived while inflation was already above target, rather than to a fundamental shift in longer-term inflation expectations. The authors say hedging is likely to improve if inflation abates and such shocks become less frequent. That is a conditional statement from the paper, not a prediction that any mix can rely on.

Does rebalancing trigger taxes?

In a taxable account, selling an investment for more than its adjusted basis creates a capital gain. The IRS treats gains on assets held more than one year as long-term and treats net short-term gains as ordinary income. Directing new contributions toward the underweight asset can reduce the amount sold.

Can inflation-linked bonds replace gold and commodities?

They fill the same inflation role differently. TIPS principal follows the Consumer Price Index and the original principal is repaid at maturity if it is higher, while gold and commodities have no such contract. TIPS prices can still fall when real yields rise.

A checklist before adopting a mix

1. Identify which of the four environments each holding is meant to help, and which it is expected to hurt.
2. Estimate each holding's share of risk, not only its weight, using at least two different historical windows.
3. Check bond duration, commodity exposure type and any leverage inside funds.
4. Add up expense ratios, trading costs and the tax cost of rebalancing in the account type used.
5. Set the rebalancing rule in writing, and decide in advance what to do if stocks and bonds fall together again.
6. Compare the worst historical decline of the mix, including 2022, with the loss you could tolerate.
