Bridgewater’s All Weather ETF Gains Traction, But Can It Deliver?

Hedge fund giant Bridgewater’s All Weather ETF is picking up steam. Six months after launch, the SPDR Bridgewater All Weather ETF (ALLW) has gathered $333 million in assets under management. 

The fund, which tracks a version of the firm’s famed All Weather portfolio, is up 6.6% since its March debut, compared with a 10.5% gain for the Vanguard S&P 500 ETF (VOO) and a 7.7% gain for the iShares Core 60/40 Balanced Allocation ETF (AOR).  

The All Weather Idea

Bridgewater founder Ray Dalio and his colleagues first built the All Weather portfolio in the mid-1990s as a way to protect Dalio’s family trust. The aim was to create a portfolio that could hold up in any economic environment. 

The framework rests on the idea that the economy moves through four different environments: rising growth, falling growth, rising inflation, and falling inflation. Different assets are expected to perform better in each. 

According to Bridgewater, stocks, commodities, corporate bonds, and emerging market debt tend to do well when growth is strong. Bonds perform best when growth is weak. Commodities and inflation-linked bonds hold up when inflation rises. And stocks and nominal bonds thrive when inflation falls.



As Bridgewater once explained, “All Weather can be sketched out on a napkin. It is as simple as holding four different portfolios, each with the same risk, each of which does well in a particular environment.”

Risk Parity

That phrase, “each with the same risk,” is central to the strategy. In a typical portfolio, money is split between stocks, bonds, and sometimes alternatives, often using a rule of thumb like 60/40. 

But despite the relatively even split, most of the actual risk comes from stocks. In fact, roughly 90% of the risk in a 60/40 comes from equities.

Risk parity strategies, like the All Weather Portfolio, are built differently. The goal is to create a mix where each part contributes the same amount of risk—usually measured by volatility—so no single piece dominates. 

To get there, the strategies often give more weight to assets like bonds and commodities until their risk contribution matches that of stocks. Because that shift would otherwise lower returns, leverage is added to bring the overall risk level of the portfolio back up to something closer to a traditional allocation like 60/40. Proponents say this can deliver stronger risk-adjusted performance than a standard portfolio.

Bridgewater’s All Weather Portfolio builds on that logic but adds another layer. Instead of just equalizing risk across asset classes, it divides the world into four possible economic environments and builds a bucket of assets for each. The portfolio then spreads risk evenly across those four buckets, on the theory that no matter what happens, at least one will deliver positive returns.

The bet is that while no one can reliably predict what type of economic environment is ahead, with this setup you don’t have to. The portfolio is designed so at least one part of it is working no matter the economic regime. 

ETF Launch

Now, for the first time, investors can access a version of Bridgewater’s All Weather strategy through an ETF.

State Street launched the ALLW exchange-traded fund in March in collaboration with Bridgewater, which provides a daily model portfolio that State Street follows. Currently, the fund is allocated roughly 79% to global nominal bonds, 43% to global equities, 38% to inflation-linked bonds, and 37% to commodities.

For three decades, the All Weather portfolio was the domain of institutional investors. With ALLW, it’s now accessible to everyday investors and advisors. The question is, should they buy in?

The Assumptions

The appeal of a portfolio that can survive any environment is obvious, but the strategy relies on assumptions that may not always hold up. Risk parity in general leans on the idea that major asset classes have historically delivered similar risk-adjusted returns.

That makes it plausible to add more bonds and commodities, reduce stock exposure, and use leverage to bring expected returns back in line with a traditional stock-heavy portfolio.

But if that assumption breaks—say stocks deliver much higher returns than expected, or bonds become more volatile and unpredictable, or commodities perform badly for long stretches—the strategy can disappoint.

Leverage introduces an additional source of risk. High borrowing costs can eat into the benefit of using leverage, reducing the portfolio’s overall return.

All Weather adds still more assumptions by framing the portfolio around four macro environments. The bet is that certain assets will shine when growth is strong, others when growth is weak, and so on. 

But those links aren’t guaranteed. Commodities, for instance, are expected to thrive in inflationary and growth-driven regimes, yet outside of gold they’ve often fallen short.

And because most commodity exposure comes through futures, roll costs can steadily erode returns. That makes implementation critical. It’s one thing to say “buy commodities,” it’s another to actually deliver that exposure in a way that works.

When Risk Parity Disappoints

The track record of existing products highlights the risks. The largest ETF in the space, the RPAR Risk Parity ETF (RPAR), launched in late 2019 and quickly grew to $1.6 billion. But in 2022, when stocks and bonds tumbled together and familiar correlations broke down, RPAR lost more than 30%, far worse than the 18% drop in VOO or the 16% loss in AOR. 

Assets have since shrunk to $524 million, and cumulative returns since inception are just 16%, compared with 49% for AOR and 121% for VOO.



For an ETF that “targets a long-term return in line with equities with less risk,” it’s been a major disappointment.

To be clear, RPAR is not identical to ALLW. It tracks the Advanced Research Risk Parity Index, which targets risk parity between TIPS, global stocks, commodities, and Treasuries with a total exposure of 120% once leverage is included.

ALLW, by contrast, is actively managed and more of a black box, with Bridgewater providing the allocations but keeping the mechanics proprietary. Since launch, the ETF has gained 6.6%, edging out RPAR’s 4.9%. 

Still, RPAR’s struggles underscore how sensitive risk parity is to shifts in market conditions and asset relationships.

The Road Ahead 

Longer-term, whether ALLW can deliver on its promise remains to be seen. Correlations between stocks and bonds may not always behave as expected, commodities may not hedge inflation as well as they have historically (oil today trades around the same nominal price it did 20 years ago), and financing costs may weigh on returns if borrowing rates remain elevated.

Another challenge is convincing investors to stick with it. In an era when equities have vastly outpaced everything else, being structurally underweight stocks can be a tough sell.

Proponents argue that stocks can’t dominate forever, and that eventually the value of a balanced portfolio will become clear. That may be true, but whether risk parity is the best way to get that balance is an open question.

It will be interesting to see whether ALLW can live up to its reputation. Plenty of institutional strategies that once looked good on paper have stumbled once packaged into an ETF.

But either way, Bridgewater’s All Weather ETF represents a marquee entry into a wide-open corner of the ETF market. And its early growth shows investors are intrigued.
