Commodity markets for equity investors

Roughly a third of S&P/TSX Composite earnings are directly tied to commodity prices. For a Canadian investor, commodity literacy is not optional specialisation — it is the revenue line of a large part of the index you already own.

Benchmark price is not the price received

Understanding the spread between a benchmark price and a producer's realized price is often more useful than the benchmark itself. Western Canadian Select trades at a discount to West Texas Intermediate because of quality and pipeline capacity; a miner's realized price reflects smelter terms and by-product credits.

Cost curves decide who survives

• A producer low on the cost curve keeps generating cash when prices fall; a high-cost producer stops.
• All-in sustaining cost is the fairest single measure because it includes the capital needed to keep producing.
• Falling prices hurt high-cost producers disproportionately — which is why equity moves are larger than the commodity move.

Volume, grade and timing

Revenue is price multiplied by volume. A strong price quarter paired with a grade or throughput problem can still miss. Read the operating statistics before the headline earnings figure.

Hedging changes the picture

A hedged producer trades some upside for certainty. Check the hedge book before assuming a company will capture a price rally — and before assuming it is exposed to a collapse.
