Investing term
What is Commodity?
A raw physical good like gold, oil, wheat, or copper — priced by the ounce, barrel, or bushel.
A commodity is a raw physical good — gold, oil, wheat, copper — priced per standard unit like an ounce, barrel, or bushel. Because one producer's barrel of a given grade of oil is interchangeable with another's, commodities trade on price alone rather than on brand or quality.
Unlike a stock or bond, a commodity produces no earnings, dividends, or interest; its return comes only from the price rising, which is driven by supply and demand. That makes it a speculation on price rather than a claim on a productive business. Some investors hold a little — often gold — as a hedge, since commodities can rise when stocks or currencies are under stress, particularly during inflation.
Stocks pay dividends and bonds pay coupons, but a commodity produces no income — you profit only if its price rises. That's why it suits a small hedging sleeve, not a core holding.
For example
When inflation spikes, the price of oil and gold often climbs while cash loses value — which is why some portfolios keep a small commodity sleeve.

Commodities matter mainly as a diversifier and inflation hedge, not as a core growth engine. Because they produce no income and rely purely on price moves, they can go long stretches earning nothing, so they suit a small sleeve rather than a big bet. Their value to a portfolio is that they sometimes zig when stocks and bonds zag — especially in inflationary shocks, where paper assets suffer and real goods hold up.
⚠ Expecting commodities to compound like stocks
A commodity generates no earnings or dividends, so it can't compound the way a business does — its price can trade sideways for years or decades in real terms. Treating a commodity as a long-term growth holding, rather than a tactical hedge, often means dead money. It's insurance and diversification, not a compounding engine.
