What Is the All Weather Portfolio
If you keep an umbrella, rain boots, and sunscreen ready, you can handle any weather, right? They say investing also has an "all-weather" portfolio—but is it really safe in any situation?
What Is the All Weather Portfolio?
All Weather is an asset-allocation strategy created by Ray Dalio, founder of Bridgewater, the world's largest hedge fund. As the name suggests, it means preparing for "all weather."
Dalio viewed the economy along just two axes. One is "growth" (is the economy improving or worsening?), the other is "inflation" (is it rising or falling?). Combining these gives four economic seasons.
① When growth is higher than expected ② When growth is lower than expected ③ When inflation is higher than expected ④ When inflation is lower than expected
The core idea is this: "No one can precisely predict which season will come. So mix assets evenly so that whichever season comes, one side holds up." Rather than predicting the future, it is a design that does not collapse much even when predictions are wrong.
Specifically, What and How Much to Hold?
The personal version Dalio introduced in an interview with Tony Robbins has these fixed weights.
• U.S. stocks 30% • Long-term Treasuries 40% • Intermediate Treasuries 15% • Gold 7.5% • Commodities 7.5%
Summed up, that is stocks 30% / bonds 55% / gold + commodities 15%. Stocks handle growth periods, Treasuries support recessions and disinflation periods, and gold and commodities do the work during inflation spikes.
Compared with a common portfolio of 60–70% stocks, stocks at 30% is quite low. Instead, bonds are more than half, so it can be seen as an allocation weighted toward "shaking less" rather than earning a lot.
The weights are not an absolute right answer but an example version Dalio proposed. Bridgewater's actual institutional All Weather fund uses leverage (debt), making its structure more complex. Keep in mind that what is introduced here is a simple version that is easy for individuals to follow.
Did It Really Hold Up Well? Looking at the Numbers
Across various backtest sources, All Weather's greatest appeal was "stability" rather than "return."
Over roughly the last 30 years, All Weather's compound annual growth rate (CAGR) is tallied at roughly a 6–8% range. Compared with the S&P 500 (the representative U.S. stock index), whose long-term annual average over the same period was roughly in the 10% range, the return is on the low side.
Instead, volatility was much smaller. In one analysis, All Weather's annual volatility was about 9%, far below the S&P 500's roughly 16%. That means it was closer to a gentle hill than a roller coaster.
The maximum drawdown (the largest fall from peak, MDD) also comes out at roughly between -23% and -26% depending on the source, which was clearly shallower than 100% stocks (which had crashes exceeding -50% in the past) or a 60:40 stock/bond portfolio (around -35% to -46%). In other words, it was a strategy that "earns less but collapses less."
CAGR and maximum drawdown come out with different numbers by source, depending on the measurement period, the ETFs used, and whether the exchange rate is reflected. That is why they are written here as a range rather than a single fixed value. No asset allocation can guarantee "no loss."
Even "All Weather" Collapsed in 2022
Despite the name "all weather," 2022 was an unusually hard year for All Weather. In that year, All Weather took a loss of roughly -22%.
Why? In 2022, as inflation soared, central banks raised rates quickly. When rates rise, bond prices fall, and All Weather had a bond weight of 55%. Long-term Treasuries in particular were shaken badly.
The problem is that stocks fell at the same time. Normally, stocks and bonds move in opposite directions and share the shock, but in 2022 the two fell together. The two pillars that were supposed to play defense collapsed together. And 15% gold and commodities was not enough to cover the entire loss.
This is the real lesson All Weather offers. Even with good diversification, in specific phases like a "rate spike," many assets can be shaken all at once. You must not mistake the name "All Weather" for "never loses."
Frequently Asked Questions
Q. Is the All Weather portfolio unconditionally a good strategy for beginner investors?
You can't declare it good or bad. Its low volatility makes it favorable for holding for a long time with peace of mind, but expected returns are correspondingly low, and its large bond weight makes it vulnerable during rate spikes. This article is not recommending a particular strategy but explaining the structure and its pros and cons. Whether it fits your own investment horizon and disposition is something you must weigh for yourself.
Q. Why hold so much when bonds are more than half?
Because Treasuries hold up relatively well when the economy worsens or inflation falls. The core design is that when stocks crash, bonds act as a cushion and reduce the overall drawdown. However, there is a limit: when rates spike as in 2022, this cushion can collapse along with everything else.
Q. Why does All Weather include gold and commodities?
To prepare for phases where inflation rises more than expected. In such periods, gold and commodity prices tend to rise even when stocks and bonds are weak, so they play the role of the portfolio's "inflation insurance." But because the weight is only 15%, it cannot fully block an extreme inflation shock.
