The traditional 60/40 portfolio relied on a negative stock-bond correlation, which has now turned positive. As investors seek diversification, a decade-long structural shift towards a 60% stock, 20% bond, 20% commodity allocation could create a massive, sustained tailwind for energy and gold stocks.
Instead of simply owning different stocks and bonds, a more robust strategy is to hold assets that perform differently under various economic conditions like high risk, instability, or inflation. This involves balancing high-volatility assets with stores of value like gold to protect against an unpredictable future.
A 100-year chart of the S&P 500 priced in gold shows a major cyclical peak was hit in late 2021, similar to 1929 and 2000. This inflection point suggests a long-term, decade-plus trend reversal favoring hard assets like gold and Bitcoin over U.S. equities.
In high-inflation environments, stocks and bonds tend to move in the same direction, nullifying the diversification benefit of the classic 60/40 portfolio. This forces investors to seek non-correlated returns in real assets like infrastructure, energy, and commodities.
The 60/40 portfolio is obsolete because bonds, laden with credit risk, no longer offer safety. A resilient modern portfolio requires a broader mix of uncorrelated assets: cash, gold, currencies, commodities like oil and food, and short-term government debt, while actively avoiding corporate credit.
After a decade of negative real returns, bonds are now attractive on a pure valuation basis relative to equities. PIMCO's CIO suggests bonds may outperform stocks over the next 5-10 years, making a compelling case for allocation regardless of their traditional role as a correlation hedge.
Owning multiple stocks or ETFs does not create a genuinely diversified portfolio. True diversification involves owning assets that react differently to various economic conditions like inflation, recession, and liquidity shifts. This means spreading capital across productive equities, real assets, commodities, hard money like gold, and one's own earning power.
Contrary to common belief, substituting the bond allocation in a traditional 60/40 portfolio with gold has historically resulted in remarkably similar overall returns. This finding challenges the conventional wisdom that bonds are the only viable diversifier for equities and suggests gold can fulfill a similar portfolio-stabilizing function over the long term.
A long-term chart pricing the S&P 500 in gold indicates that US financial assets peaked in 2022. This signals the start of a 10-15 year cycle where hard assets like gold, commodities, and emerging market equities are poised to outperform US stocks.
With inflation becoming less of a concern in 2026, bond yields will be driven more by growth expectations than inflation risk. This restores their traditional negative correlation with equities, making them a more reliable diversifier and hedge against a potential economic downturn in portfolios with long-risk exposure.
Arguing against the traditional 60/40 portfolio amidst a market mania, Gundlach advises a radically different allocation. He suggests a maximum of 40% in stocks (mostly non-US), 25% in bonds (with non-dollar exposure), 15% in gold and real assets, and the rest in cash.
