Gold vs stocks over the long term

The structural difference

A share is a claim on a business's future cash flows. Companies earn, reinvest and pay dividends; even if the share price never rose, a dividend-paying portfolio would produce income. That is why equities have a rational basis for a positive long-run expected return.

Gold produces nothing. It pays no dividend, no interest and no rent, and holding it physically costs money (storage, insurance, spreads). Its entire return is the change in price — which means its value depends wholly on what the next buyer will pay. That is not a criticism; it is a description, and it explains why the two assets behave so differently.

What the long-run evidence supports

The most careful long-run dataset for this comparison is the Dimson–Marsh–Staunton work behind the annual Global Investment Returns Yearbook, which tracks equities, bonds, bills, inflation and gold across more than twenty markets since 1900. Its findings on gold are consistent across editions and worth stating plainly:

• Over the very long run, equities have substantially outperformed gold in real terms in the markets studied.
• Gold has roughly preserved purchasing power over very long horizons, but with long multi-decade stretches of significant real loss. “Preserves value” is true on a century scale and frequently false on a twenty-year one.
• Gold's usefulness in a portfolio comes mainly from its low correlation with equities, not from its expected return.

FinSage deliberately does not publish a single headline “gold returned X%” figure, because the answer depends enormously on the start and end dates chosen — gold was under price control for part of the twentieth century, and any comparison starting at the 1980 or 2011 peaks tells a very different story from one starting a few years either side. If a source quotes one number without a window, treat it with suspicion.

Does gold hedge inflation?

Partly, and unreliably. The relationship holds over very long periods and breaks down over the horizons most people actually invest across. There have been decade-long stretches of meaningful inflation during which gold fell in real terms, and stretches of low inflation during which it rose sharply.

Assets with a more direct inflation link exist: inflation-linked government bonds pay a coupon explicitly tied to a price index, which gold does not. If hedging inflation is the specific goal, that is the more direct instrument — where your market offers it.

Crisis behaviour and volatility

Gold's real portfolio argument is diversification. It has frequently risen, or fallen less, during equity crises and periods of currency stress, which can reduce overall portfolio drawdown. But:

• It is not low-volatility. Gold's own price swings are comparable to equities'.
• The negative correlation is not dependable; there are episodes where both fell together, notably when liquidity was scarce and everything was being sold.
• Because it yields nothing, holding a large allocation for decades has a real opportunity cost.

The ways to own it differ more than people expect

How to think about an allocation

There is no consensus “correct” gold weighting, and anyone who states one confidently is expressing a preference. What is defensible:

1. Decide why you want it — diversification, currency-debasement insurance, or a view on the price. Only the first two are portfolio arguments.
2. Size it so that being wrong is survivable. A position small enough not to matter in a good decade is also small enough not to rescue you in a bad one; that trade-off is the decision.
3. Decide the rebalancing rule in advance, since gold's long flat periods are exactly when people abandon the position.
4. Count the cost: fees, spreads and storage come out of a return that has no yield to fund them.

And keep the ordering sane: an emergency fund, cleared high-interest debt and a diversified core portfolio all outrank a gold allocation for almost everyone.
