What Is the Permanent Portfolio?
The Permanent Portfolio is a simple 4-slice portfolio created by investment advisor Harry Browne in the 1980’s and presented in his book Fail-Safe Investing in 2001. It looks like this:
- 25% Total US Stock Market
- 25% Long-Term Bonds
- 25% Cash
- 25% Gold
Not unlike the All Weather Portfolio, the Permanent Portfolio was designed to be a simple, diversified portfolio that could perform well in all economic conditions. Browne called it the Permanent Portfolio because, in his words, “once you set it up, you never need to rearrange the investment mix— even if your outlook for the future changes.”
Having only 4 assets at equal weights, it is easily accessible and understandable. Those 4 assets’ expected behaviors correspond to 4 economic climates as follows:
- Stocks – economic expansion
- Bonds – deflation
- Cash – economic recession
- Gold – inflation
Permanent Portfolio Review
I concede that Harry Browne’s Permanent Portfolio is indeed simple and diversified, and the concept sounds nice on paper. But I have a few problems with it.
First, there’s the relatively low allocation to stocks. We know that equities are usually the primary driver of a portfolio’s returns. At just 25%, the Permanent Portfolio doesn’t give enough room for stocks to shine, especially for the young investor with a long time horizon and a high tolerance for risk.
Secondly, 25% of the portfolio is in cash, which just means treasury bills. I’ll be the first to admit that cash is an oft-overlooked investment, but giving it 1/4 of the portfolio creates a significant opportunity cost in my opinion, especially when considering economic depressions are the least likely environment of the 4 aforementioned economic climates and young investors with a long horizon probably shouldn’t be holding any cash. As such, I would think it’s intuitive to lower the allocation to cash, creating room for more stocks and/or more bonds. In fairness, cash is a decent inflation hedge.
Thirdly, there are no international (ex-US) holdings. International stocks and bonds have just fairly recently become “accepted” diversification-boosting holdings in the last 25 years or so. Prior to that, they weren’t popular among institutional investors, so it makes sense that Browne didn’t include any when he designed the Permanent Portfolio in the 1980’s. Ideally I’d probably like to see at least an 80/20 split for both stocks and bonds between the US and ex-US assets. I delved into the benefits of geographical diversification here.
Similarly, 25% to gold is much too high for my tastes. If you’ve read any of my other posts on portfolios that utilize gold, you know I’m not a big fan of the metal. It has a nonnegative correlation to stocks, albeit low/small, is much more volatile than bonds, is not a value-producing asset (it has a real expected return of zero), and has not been a reliable inflation hedge historically. While it has offered protection in some inflationary periods in the past, we can’t reliably predict how gold will behave in the future.
I suspect the large emphasis on gold may be due at least partially to Harry Browne’s being the Libertarian Party presidential nominee in both 1996 and 2000. The Libertarian Party platform has a historical distrust of US monetary policy by the Federal Reserve and a suggestion of returning to the gold standard, wherein money is based on a fixed amount of physical gold.
Speaking of US monetary policy, your excitement – or lack thereof – over gold likely also depends on your view of it. I’m personally of the mind that monetary policy in the United States is a fundamentally different beast post-Volcker (1982), allowing us to [hopefully] avoid a runaway inflationary environment like we saw in the late 1970’s, when bonds suffered and gold did well.
In my opinion, similar to my point about the cash position above, in a long-term investment portfolio with an investment horizon of 20+ years, holding gold only creates an opportunity cost where you could have held something else in its place. That said, I’ll concede that it may offer a short-term diversification benefit due to its usual uncorrelation to both stocks and bonds, making for a lower risk profile and safer withdrawal rates in retirement, so adopting the Permanent Portfolio may very well be a prudent move at or near retirement, or for a risk-averse investor who wants to cover all bases for all environments to minimize volatility and risk, but even then I’d probably suggest the All Weather Portfolio or the Golden Butterfly Portfolio for that prescription. We can explore some comparisons of these below.
Because of all this, generally speaking, Browne’s naive equal weighting of these assets doesn’t make much sense intuitively and is almost certainly suboptimal. This becomes even more obvious when we consider the fact that the four aforementioned environments do not have the same probability of occurrence. Severe, protracted deflation, for example, is extremely unlikely. Browne makes the mistake I see far too often of viewing each asset in isolation instead of looking at the portfolio holistically.
As we would expect, compared to something simpler and more “traditional” like a 60/40 stocks/bonds portfolio, the Permanent Portfolio tends to look attractive during bear markets and unattractive during bull markets, evidenced by the mutual fund’s capital inflows and outflows during those respective periods.
Permanent Portfolio Performance vs. S&P 500
Going back to 1978, we can compare the Permanent Portfolio to the S&P 500 index through July, 2021:
As we’d expect, the Permanent Portfolio does a pretty great job of mitigating volatility and drawdowns, providing a much smoother ride than the S&P 500. Its volatility was less than half that of the S&P 500, and its max drawdown during the Global Financial Crisis of 2008 was roughly 1/4 that of the S&P 500. But notice how the risk-adjusted return (Sharpe) is nearly the same for these two very different portfolios.
Basically, the Permanent Portfolio has still delivered a pretty low return given its risk profile. That’s why I said I’d be more likely to use the Golden Butterfly Portfolio or the All Weather Portfolio. I’ll show those comparisons in the next sections.
Permanent Portfolio vs. Golden Butterfly Portfolio
The Golden Butterfly Portfolio simply takes those same assets in the Permanent Portfolio and specifically adds Small Cap Value, a move that I’m a fan of. This invariably makes it comparatively more “aggressive” than the Permanent Portfolio, but we’re still talking about a relatively low-volatility, all-seasons portfolio.
In taking up a larger stock position, we’re also tilting toward an expansionary economic environment. I’m okay with this; the economy grows more than it declines. Your adoption thereof may depend on your economic outlook. We’re also simultaneously decreasing the allocations to cash and gold, which should also bode well for higher returns.
Here’s a backtest from 1978 through July, 2021 comparing the Permanent Portfolio and the Golden Butterfly Portfolio:
As we’d expect, going back to 1978, we see greater general and risk-adjusted returns for the Golden Butterfly, with slightly more volatility and a larger drawdown. This is due again to its inclusion of small cap value stocks. Looking at the Sharpe ratios, a measure of risk-adjusted return, we can see that we were better compensated per unit of risk by going with the Golden Butterfly Portfolio.
I’d definitely take the Golden Butterfly over the Permanent Portfolio. Again, I like small cap value stocks, and I don’t want the Permanent Portfolio’s extra 5% in gold. To be fair to Harry Browne, we didn’t even know about the Size and Value factors and the glamour of small cap value stocks when he designed this thing in the 1980’s, and even if we did, there weren’t really any products available with which to invest in them.
Permanent Portfolio vs. All Weather Portfolio
Compared to Ray Dalio’s All Weather Portfolio, we’re talking about more gold, more cash, less stocks, and less treasuries with the Permanent Portfolio. Like the Permanent Portfolio, the All Weather Portfolio is designed to “weather” any storm by utilizing diversification.
Interestingly, like Browne, Dalio also chooses to be market-agnostic with the All Weather Portfolio, admitting that we don’t know what the future will hold, yet the allocations therein are obviously very different.
With data for Commodities funds only going back to 2002, here’s what the comparison looks like through July, 2021:
Results have been pretty close for that time period. The All Weather Portfolio still won out on total return, and they ended up with basically an identical risk-adjusted return.
Let’s explore an alternative. If you’re like me, you might replace Commodities (I think they’re pretty awful) in the All Weather Portfolio with Utilities (I delved into this here). Making that change, we can get data going back to 1991 through July, 2021, and the results are pretty different:
While the All Weather Portfolio had slightly greater risk metrics (volatility and max drawdown), it handily beat the Permanent Portfolio on both general and risk-adjusted returns.
In this sense, again, while the Permanent Portfolio is very simple and easy to understand with its equal weighting of 4 assets, that’s also its downfall. I’m of the mind that we can much more effectively deliver on the Permanent Portfolio’s goal of de-risking the portfolio using different allocations, especially given our most recent understanding of asset pricing and how we might weight those assets more efficiently in diversified portfolios.
Permanent Portfolio ETF Pie for M1 Finance
If you do want to invest in the Permanent Portfolio, M1 Finance is a great fit thanks to its zero transaction fees, dynamic rebalancing for new deposits, and one-click manual rebalancing. I wrote a comprehensive review of M1 Finance here.
Utilizing mostly low-cost Vanguard funds, we can construct the Permanent Portfolio pie for M1 Finance with the following ETF’s:
- VTI – 25%
- VGLT – 25%
- VGSH – 25%
- SGOL – 25%
Taking the Permanent Portfolio International
As I noted earlier, the Permanent Portfolio doesn’t have any international exposure. It’s probably a good idea to diversify geographically in stocks. Taking the stocks global simply requires replacing VTI (Vanguard’s total US stock market) with VT (Vanguard’s total world stock market). The portfolio and subsequent pie then look like this:
- VT – 25%
- VGLT – 25%
- VGSH – 25%
- SGOL – 25%
Leveraged Permanent Portfolio
What about creating a leveraged Permanent Portfolio? As I noted above, the Permanent Portfolio itself isn’t super impressive in my opinion. But, as with the All Weather Portfolio, levering up those same assets may enhance returns while maintaining a reasonable risk profile similar to that of a 100% stocks position.
Just remember that using leverage – especially in the form of leveraged ETFs – increases portfolio risk and the potential for greater returns, but also the potential for greater losses. Do your own due diligence before blindly buying leveraged funds, and read the fine print on these products. They can potentially be extremely dangerous. I talked a bit more about leveraged ETFs and how they work here.
Having 25% cash and 25% long bonds is roughly the same as 50% intermediate bonds. Ideally, a 3x leveraged Permanent Portfolio would look like this:
- 25% 3x U.S. Stocks
- 50% 3x Intermediate Bonds
- 25% 3x Gold
Unfortunately, there are now no 3x gold ETFs available after UGLD went away. The next best option is UGL, which is 2x gold. Using that, we can achieve the intended exposure at 2.67x leverage like this:
UPRO – 22%
TYD – 45%
UGL – 33%

Here’s how this would have worked out historically going back to 1987 versus the Permanent Portfolio and the S&P 500:
Interestingly, the leveraged version achieved higher general and risk-adjusted returns than the “normal” unleveraged Permanent Portfolio and the S&P 500.

The Permanent Portfolio is basically a good introductory lesson on asset class diversification in my opinion. And props to Harry Browne for making the concept more mainstream. The Permanent Portfolio does a pretty good job of mitigating volatility and drawdowns, but in practice I’d be more likely to use the All Weather Portfolio or the Golden Butterfly Portfolio to achieve that goal. They seem demonstrably superior, as the Permanent Portfolio’s simplicity is ironically also its weakness in my opinion. I created an arguably simpler, more aggressive portfolio with 3 assets called the Neapolitan Portfolio – and a much more complex one called the Factor Tank Portfolio – if this idea of extreme diversification intrigues you.
If all this multi-fund stuff still seems daunting, there’s a Permanent Portfolio mutual fund for which the ticker is PRPFX. But it’s pretty pricey at 0.83%. You’d come out far cheaper just using the funds I listed above and doing it yourself.
