In an economy where currency is being systematically devalued through money printing, holding cash is a losing strategy. The only way to preserve wealth is to own a diverse basket of 12-15 uncorrelated assets (e.g. stocks, commodities, real estate) that are subject to different economic pressures.

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The 60/40 portfolio is obsolete because bonds, laden with credit risk, no longer offer safety.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.

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.

The real benefit of diversification is matching assets with different time horizons (e.g., long-term stocks, short-term bills) to your future spending needs. All asset allocation is ultimately an exercise in managing financial goals across time.

During profound economic instability, the winning strategy isn't chasing the highest returns, but rather avoiding catastrophic loss. The greatest risks are not missed upside, but holding only cash as inflation erodes its value or relying solely on a paycheck.

A more robust diversification strategy involves spreading exposure across assets that behave differently under various macroeconomic environments like inflation, deflation, growth, and contraction. This provides better protection against uncertainty than simply mixing asset classes.

Bridgewater's Co-CIO argues the winning formula of the last 15 years—concentrating capital in US equities and illiquid assets—is now a dangerous trap. He believes most investors have abandoned diversification because it hasn't worked recently, creating a risky setup that calls for a globally diversified portfolio.

The goal of diversification is to hold assets that behave differently. By design, some part of your portfolio will likely be underperforming at all times. Accepting this discomfort is a key feature of a well-constructed portfolio, not a bug to be fixed.
