Gold occupies a peculiar position in investing. It's simultaneously marketed as the ultimate safe haven, dismissed as a useless rock, and pushed relentlessly by advertisers who benefit from fear. Commodities more broadly — oil, metals, agricultural goods — get similar treatment. The truth is more measured: these are legitimate assets with a specific role and a significant limitation that separates them from stocks and bonds.
What are commodities?
Commodities are raw physical materials that are traded: precious metals like gold and silver, energy such as oil and gas, industrial metals like copper, and agricultural products including wheat and coffee. What unites them is that one unit is essentially interchangeable with another — a barrel of a given oil grade is the same wherever it comes from. Their prices are driven largely by supply and demand for the physical material, which behaves quite differently from what drives company shares.
The limitation that defines them
Here's the crucial distinction, and it's not a small one. A share in a company represents ownership of a business that produces something — it can generate profits, pay dividends, and grow. A bond pays interest. Gold sits in a vault. Commodities generate no income: no dividends, no interest, no earnings. Their entire return depends on someone paying more for them later than you did.
That's why long-term wealth building rests on productive assets. Over long horizons, an asset that compounds through earnings behaves fundamentally differently from one that just sits there — which is the whole logic behind compound interest and why index funds form the core of most sensible portfolios. Gold has no earnings to compound.
| Asset | Produces income? | Return comes from |
|---|---|---|
| Stocks | Yes — earnings, dividends | Business growth plus income |
| Bonds | Yes — interest | Interest payments |
| Commodities / gold | No | Price change only |
So why hold them at all?
Because they can behave differently from stocks and bonds, and that difference has value. Gold in particular has a long history of being sought during periods of crisis and uncertainty, and commodities can respond to inflationary conditions that hurt other assets — relevant to the erosion described in inflation and your money. When an asset doesn't move in step with the rest of your portfolio, adding a modest amount can smooth the overall ride, which is exactly the mechanism in portfolio correlation. That's the honest case for a commodity allocation: diversification, not returns.
Worth tempering, though — gold's reputation as a reliable inflation hedge is more mixed than the marketing suggests, and it can be volatile and go through long stretches of poor performance. It is not a guaranteed safe haven.
How to hold them, if you do
Physical gold means storage, insurance, and dealing with buy-sell spreads that can be wide. Most investors instead use funds or ETFs tracking gold or a broad commodity basket, which are far more practical. Beware anything involving leverage or futures-based products with complex structures unless you fully understand them — the risks in futures trading are substantial. And be sceptical of the marketing: gold is aggressively advertised to people worried about the economy, frequently by firms charging high premiums over the metal's actual value. Fear sells well.
How much is reasonable?
If you include commodities at all, they belong as a small slice of a diversified asset allocation rather than a core holding — something to smooth the ride, not to drive returns. Many perfectly sound portfolios contain none at all, and that's a legitimate choice, not an oversight. The danger is the opposite: someone frightened by headlines moving a large share of their savings into gold, abandoning the productive assets that actually build wealth over decades. A portfolio built on fear tends to underperform one built on patience.
Frequently asked questions
Is gold a good investment? It can serve as a diversifier because it often behaves differently from stocks and bonds, but it produces no income and its returns depend entirely on price movement. It's better understood as portfolio insurance than as a wealth-building engine.
Does gold protect against inflation? Its record as an inflation hedge is more mixed than commonly claimed — it has performed well in some inflationary periods and poorly in others. Treat it as one imperfect diversifier rather than a reliable shield.
How much gold should I hold? If any, a small portion of a diversified portfolio — enough to diversify, not enough to depend on. Many well-constructed portfolios hold none. Large allocations driven by economic fear tend to work against long-term returns.
Should I buy physical gold or a fund? Physical gold involves storage, insurance, and often wide buying and selling spreads. For most investors a fund or ETF is more practical and cheaper, though it means you don't hold the metal itself — a tradeoff worth understanding.
The bottom line
Commodities and gold are legitimate diversifiers that behave differently from stocks and bonds, which is genuinely useful in a portfolio. But they produce no income, so returns depend purely on price movement — making them a poor engine for long-term wealth. Keep any allocation modest, access them through funds rather than physical metal, ignore the fear-based marketing, and let productive assets do the compounding.
Understanding what an asset can and can't do is risk management — the same discipline that underpins any serious market approach. The Asymmetric Trader's Playbook ($29, reg. $39) is a risk-first framework built on exactly that clarity about risk before return.
