Permanent Portfolio DMS Overview

Permanent Portfolio DMS is a modernized version of Harry Browne's 1981 Permanent Portfolio. It keeps Browne's philosophy exactly as he stated it, four equal quadrants covering prosperity, inflation, recession and crisis, and replaces each original holding with a more capable modern instrument.

There are no signals, no forecasts and nothing to monitor. The portfolio rebalances once a year, plus whenever a quadrant drifts far enough out of line to matter.

Where It Comes From

Harry Browne introduced the Permanent Portfolio in Inflation-Proofing Your Investments in 1981, and restated it more simply in Fail-Safe Investing in 1999. The reasoning starts with humility: nobody knows what the economy will do next, so rather than predict, own something built for each environment it might produce.

Browne identified four, and gave each a quarter of the portfolio: prosperity, inflation, recession or deflation, and tight money. The original construction and the full story behind it, including Browne's two runs for President, are on its own page. This version keeps his philosophy and his weights exactly, and upgrades the instruments.

What Changed, and Why

Browne chose the best instruments available to an individual investor in 1981. Several of those choices were constrained by what existed then rather than by what the quadrant actually needed. This version keeps every quadrant and every weight, and upgrades the tools.

Quadrant	Browne's original	Here	Why
Prosperity	Broad stocks	CLSE 12.5% + HFGM 12.5%	Long/short equity and global macro equity pursue equity-like returns with active downside management, rather than riding a bull market all the way back down
Inflation	Gold bullion	SGOL 25%	The same asset in an ETF wrapper. Nothing about this role needed improving
Recession	Cash and T-bills	DBMF 25%	Managed futures have historically outperformed cash during contractions, and can profit outright in sustained downtrends
Crisis / deflation	Long-term Treasuries	CAOS 25%	Convex payoffs in a dislocation without depending on the rate environment being favorable

The two substitutions worth explaining are the last two.

Long Treasuries were replaced because the role, not the asset, is what matters. Browne wanted something that pays off when everything else is falling apart. Long Treasuries did that for four decades because rates were falling for four decades. In 2022 they fell alongside stocks and provided no protection at all. A tail-risk fund built to benefit from volatility spikes and market dislocations fills the same role without requiring rates to cooperate. This is the portfolio's insurance policy, and at 25% it is held with full conviction.

Cash was replaced because cash only preserves. Browne's recession quadrant was there to hold value and provide liquidity for rebalancing. Managed futures do that while also being able to profit from sustained trends in either direction, which is exactly what a long contraction produces.

The philosophy is untouched. Four quadrants, equal weight, no forecasting, annual rebalancing. Only the instruments changed.

How It Works

The four quadrants

Each quadrant holds 25% of the portfolio. The prosperity quadrant splits its share between two funds; the other three hold one each.

Equal weighting is the philosophy rather than a convenience. Overweighting any quadrant requires a prediction about which environment is coming, which is the thing this portfolio refuses to do. Each leg is sized to matter when its moment arrives.

The four regimes are not equally likely at any given moment, but they are equally unknowable in advance. A portfolio prepared for all of them does not need to be right about the future. It only needs to survive it, and compound through it.

Rebalancing

Once a year, and additionally whenever any quadrant drifts below 15% or above 35% of the portfolio. Between those points nothing happens.

The bands do real work. A quadrant that has run up gets trimmed back toward target, which mechanically sells what has done well and buys what has not. That is where a meaningful part of the long-run return of any equal-weight all-weather portfolio comes from. See rebalancing and drift bands for how the mechanism works in general.

No signals at all

Nothing in this portfolio reads a momentum score, a moving average or a macro indicator. There is no risk-on or risk-off state. The holdings are the same in every environment, which is precisely what makes it holdable.

Performance Highlights

Over the full published history, alongside Browne's original construction and two other all-weather portfolios:

January 1980 through September 2026, net of trading friction:

	CAGR	Max Drawdown	Ulcer Index	UPI
Permanent Portfolio DMS	+10.0%	-10.9%	2.64	2.20
Permanent Portfolio	+7.4%	-15.7%	3.16	1.02
Golden Butterfly	+8.6%	-17.3%	3.57	1.22
60/40	+9.8%	-32.3%	6.22	0.90
S&P 500	+12.0%	-51.0%	12.72	0.61

The second row is Browne's original four-asset construction, run on the same data with the same trading costs: broad U.S. stocks, long Treasuries, gold and cash at 25% each. It is shown for comparison and is not a strategy published here.

The third column is the Ulcer Performance Index: return above cash divided by how deep the portfolio went and how long it stayed there. Max Drawdown reports the worst single moment; UPI reports the experience of holding it. Higher is better.

The comparison between the first two rows is the case for this version. Same philosophy, same weights, same absence of signals, and the modernized instruments add roughly two and a half points of annual return while taking a shallower worst decline. The improvement comes from replacing two quadrants whose original instruments were tied to a specific rate environment.

Against 60/40 it earns a similar return with a third of the drawdown. Against the index it gives up a couple of points a year and holds its worst decline to about a fifth. Against Golden Butterfly, which pursues the same goal with a different set of quadrants, it earns more with a shallower decline.

The same five, measured from January 2000:

January 2000 through September 2026, net of trading friction:

	CAGR	Max Drawdown	Ulcer Index	UPI
Permanent Portfolio DMS	+8.5%	-10.9%	3.11	2.14
Permanent Portfolio	+6.9%	-15.7%	3.33	1.50
Golden Butterfly	+8.0%	-17.3%	3.62	1.68
60/40	+6.6%	-32.3%	7.62	0.62
S&P 500	+8.1%	-51.0%	15.89	0.39

The recent window is kinder to every all-weather portfolio here, because it contains two equity declines of roughly half and a year when stocks and bonds fell together. This version matches the index's return over that period with a fifth of its worst decline, and it stays ahead of the original construction on every measure.

Note that both Permanent Portfolio rows show identical worst declines in the two tables, meaning their deepest drawdowns came after 2000 rather than during the 1980s or 1990s.

Two cautions apply as always. Portions of this record rely on reconstructed data for funds that did not exist for the full period, which is a larger caveat here than for most strategies on this site, since three of the five holdings are recent and specialized. And a single figure covering four decades says nothing about the order the returns arrived in, which is most of what an investor lives through.

Portfolio Characteristics

• No signals, ever. Nothing is read, ranked or timed. The holdings are the same in every environment.
• Four equal quadrants. Prosperity, inflation, recession and crisis, at 25% each, by design rather than by optimization.
• Annual rebalancing with drift bands. Once a year, plus a trigger if any quadrant falls below 15% or rises above 35%.
• Crisis protection that does not need low rates. A tail-risk fund replaces long Treasuries in the role Browne assigned them.
• Recession quadrant that earns. Managed futures in place of cash, which can profit in a sustained downtrend rather than merely holding value.
• Deliberately never the best performer. In any given year, something will beat it. That is what the construction accepts in exchange for never being badly hurt.
• No leverage. Permanent Portfolio DMS never holds a leveraged fund.
• Low turnover. One scheduled rebalance a year and occasional triggered ones, with no trading in between.
• Reasonable in a taxable account. Low turnover makes this one of the few strategies here that does not strongly prefer a tax-deferred account.
• Five holdings. Simple enough to run manually and to keep running for decades.

Who It's For

Permanent Portfolio DMS is designed for investors who want:

• A portfolio that requires no forecasting, no monitoring and no decisions.
• Protection spread across every economic environment rather than concentrated against one.
• Shallow drawdowns and a return stream steady enough to hold through anything.
• Low turnover and reasonable tax treatment.
• Something that can be left alone for a decade without becoming inappropriate.

It is a poor fit for investors seeking maximum growth, who would be frustrated watching equities run ahead of them during a bull market, or who want the portfolio to react to conditions. Investors who want the same all-weather goal with a growth tilt should look at Golden Butterfly or All Weather. Those who want an alternative-heavy portfolio with more return should compare it with Falcon, and those wanting shallow drawdowns from an active design should look at Quiet Compounding.

The Permanent Portfolio concept was created by Harry Browne. This is an independent modernization of it and is not affiliated with or endorsed by his estate or by any fund bearing the Permanent Portfolio name.

Past performance, including backtested results, is not indicative of future results. Backtested performance is hypothetical, does not reflect actual trading, and benefits from hindsight in the selection of holdings. Portions of the long-term history rely on reconstructed proxy data for funds that did not exist for the full period. Investors should carefully consider their risk tolerance and consult with a financial advisor.
