Commodities: The Curve Is the Trade
Commodities are raw physical goods traded in standardized form — energy, metals and agricultural products. They generate no earnings and pay no dividend, so the return on a held position comes from price change and from what each futures roll costs or earns.
How it works
They are physical goods traded in standardized units. Energy, metals, and agricultural products — grouped because the same thing is true of all of them: one unit is interchangeable with another, which is what makes a market in them possible.
The price answers a physical question. How much exists, where it is, how much is wanted, and how quickly either side can change. There is no management team, no strategy and no earnings — which makes them simpler to think about and harder to value.
The cycle is self-correcting and slow. A high price makes production profitable, so mines open and acreage is planted — but years later, and usually all at once, into a market that no longer needs it. That lag is why commodity cycles run for years rather than quarters.
Some have real seasonality, which is unusual. Harvests arrive, heating demand rises in winter. These are mechanisms rather than patterns found by searching, which puts them in a different category from most calendar effects.
The curve is where the money goes
Physical goods cost money to keep. Storage, insurance and financing mean a contract for delivery next year normally prices above one for delivery next month, and that difference is not a forecast — it is the cost of holding the thing.
Holding a view past expiry means rolling, and each roll sells the near contract and buys a dearer far one. Over a year of monthly rolls that can cost more than the price move you were right about. When the curve is the other way up, the roll pays you instead — and that is the whole difference between a commodity position that works and one that does not.
There is nothing to discount. A share can be valued from the cash it will produce; a tonne of copper produces nothing. Which means no valuation model applies, and “expensive” only ever means expensive relative to history or to the cost of producing more.
In practice
A commodity fund is a rolling futures position with a wrapper. It does not hold the goods; it holds contracts and rolls them on a published schedule, so its return can differ substantially from the spot price it appears to track.
Depth is concentrated in a few contracts. Crude oil and gold trade continuously and in size; several agricultural contracts barely trade outside their front month.
The horizon is long because the physical response is slow. A mine takes years to open, which is why these markets trend for extended periods and then reverse hard.
News here is physical. A frost, a strike, a blocked shipping route — supply shocks arrive as an opening gap rather than a drift.
Which is why a close stop is unreliable. Position size, not stop placement, is the defense against a market that moves in steps.
And the trading cost sits on top of the roll cost. Each roll closes one contract and opens another, so the spread and commission are paid again every time, in addition to whatever the curve is charging you to hold.
The inflation argument, examined
Commodities are widely recommended as an inflation hedge, and the reasoning is sound as far as it goes. They are physical inputs, so when the price of things rises, the price of things rises.
What the argument usually omits is the roll. A position held through a period of rising prices still pays the carry every month, and that cost is invisible on the spot chart people point at when making the case. The hedge works on the price and is charged against the holding, which is why the historical record for commodity funds so often disappoints people who bought the story.
What commodities are not
They are not a business. There are no earnings.
They are not the spot price. You hold contracts.
They are not a passive holding. Rolling is active.
And they are not free of carry. Time costs money here.
How this connects
The opposite of storage cost is convenience yield. When a good is scarce now, holders value having it on hand, and near contracts can price above later ones.
Hedging is why these markets exist at all. Producers sell ahead and consumers buy ahead, and a privately negotiated forward contract does the same job as an exchange contract without the daily margin.
No hedge is exact, because of basis risk. The local grade or delivery point a business actually deals in rarely matches the benchmark contract it hedges with.
Contract size decides who can take part. The standard lot size on many commodity contracts is large, which is why micro futures exist on several of them, and why leverage can turn a supply shock into a margin call before the next session.
Gold can also be held as bullion, which avoids rolling entirely and swaps it for storage and insurance.
Most are priced in United States dollars, so currency risk sits inside the position for anyone measuring returns in another currency, and producing regions add country risk.
Trend following grew up in these markets, where slow physical adjustment produces long, persistent runs.
And the inflation link is usually judged against the consumer price index, where energy and food are among the most volatile components.
When it fails
In a flat market the price does nothing and the roll continues. A year of correct-but-sideways can produce a loss purely from carry, which is the failure people least expect.
The second is buying the story and holding the fund. The fund tracks contracts, not the headline price.
A third is treating a supply shock as a trend. A frost is a level change, not a direction, and once it is priced in the price can simply sit at the new level.
A fourth is sizing from a calm period. These markets gap, and a stop does not protect against that.
A fifth is assuming the cycle turns on schedule. Production responds in years and overshoots.
And a sixth is applying valuation language. Nothing here has an intrinsic value to be cheap against.
The original data
Of the 24,971 videos in the search study behind this site, 25 have “commodity” in the title, at a median of 5,675 views across 25 channels, with a maximum of 730,251. Gold appears in 371 at a median of 8,194, silver in 84 at 3,681 and oil in 25 at 5,602. Repeat appearances of the same video count once.
The question: Supply is tight and the curve says otherwise. Which?
Gold alone is covered fifteen times more often than commodities as a category, at a higher median. The metal with a story attached draws the audience; the asset class that actually requires understanding the curve does not. Twenty-five channels made twenty-five videos, so nobody made two.
The answer to that final question is that the curve is a price and the tightness is an opinion. The curve is where real money has already committed to storage and delivery, so a view that contradicts it is a view that everyone financing the physical trade is wrong. Before taking the position, work out what a year of rolling would cost you — if the carry exceeds the move you expect, being right will not be enough.

Futures is the instrument this is all conducted in, and where the roll happens. Gold trading is the one commodity most people meet first, and the least typical. And inflation and savings is the argument most often made for owning any of it.
A view on the price is not enough. You can be right about the direction for months and make almost nothing if each contract you roll into costs more than the one you are leaving. Holding a commodity position has a running cost built into its structure, and the chart of the spot price does not show it.
