The basic materials sector: a concise explainer
What it is (definition)
– The basic materials sector (also called the materials sector) groups companies that find, extract, develop, or do the first-stage processing of naturally occurring resources. Examples of those resources are metals and ores, lumber, certain chemicals, and some energy commodities.
– “Raw materials” here means inputs used in manufacturing or construction in a near‑initial form — e.g., iron ore, timber, crude oil, natural gas, and basic chemicals. “Refined products” are processed forms of those resources that still have broad industrial use (for example, gasoline).
How the sector is structured (components)
– Mining and metal refining: producers of metals and ores (iron, copper, gold, etc.).
– Forestry and paper: logging, sawmills, pulp and paper makers.
– Basic chemicals: producers of bulk chemicals used as industrial inputs.
– Construction materials and aggregates: producers of crushed stone, cement, concrete, and related products.
– Packaging and industrial glass/metal containers.
– Certain energy commodities: natural gas, crude oil and some widely used refined fuels are frequently treated as part of the materials universe because of their fundamental role in industry.
What the sector’s stocks tend to do
– Cyclical exposure: demand for basic materials tracks economic activity. When manufacturing, construction and consumer-goods production expand, materials demand tends to rise; when consumer and business spending contract, demand — and material prices — often fall.
– Sensitivity to commodity prices: many materials companies’ profits move strongly with the prices of the commodities they produce, and those prices are set in global markets.
– Capital intensity and reserves: production capacity, unit costs, reserve life and capital expenditures are central to long-term prospects for mining and similar businesses.
What is and isn’t included
– Included: companies that directly produce or initially process raw materials.
– Excluded: downstream retailers or luxury product makers that buy raw materials and sell finished goods (for example, a jeweler or a furniture retailer is usually classified outside the materials sector).
– Not every chemical company is in the basic materials sector — specialty chemicals or pharmaceutical-type businesses may be categorized elsewhere.
Practical checklist for evaluating basic materials stocks or funds
1. Identify the primary commodity exposure (iron, copper, timber, oil, chemicals, etc.).
2. Check commodity price
2. Check commodity price history and volatility
– Look at long-term real (inflation-adjusted) and short-term nominal price charts. Commodity cycles can last years; recent spikes or troughs may reverse.
– Measure volatility (standard deviation) and drawdowns. Higher volatility means higher operational and balance-sheet risk for producers.
– Note seasonality for some commodities (timber, soft commodities, certain chemicals).
3. Assess supply–demand fundamentals
– Supply: current production, planned capacity additions, mine/reserve depletion rates, and geopolitical supply risks (export controls, trade disputes).
– Demand: end-use industries (construction for steel/iron, electronics for copper, packaging for plastics), substitution risk, and macro factors (global GDP growth, infrastructure programs).
– Check inventories and stock-to-use ratios where available (e.g., metals exchanges, industry reports).
4. Calculate unit economics and break-even price
– Key terms:
– Unit cost: the average cost to produce one unit (e.g., per pound, per tonne). May be reported as cash cost or all-in sustaining cost (AISC) for miners. AISC includes sustaining capex and corporate overhead.
– Break-even price: the commodity price needed to cover costs and fixed obligations.
– Core formulas:
– Profit = (Price − UnitCost) × Quantity − FixedCosts
– Break-even Price = UnitCost + (FixedCosts / Quantity)
– Worked example (miner producing copper):
– Quantity = 50,000 tonnes = 50,000 × 2,204.62 = 110,231,000 lb
– UnitCost (cash) = $2.50 per lb
– Market Price = $3.50 per lb
– FixedCosts = $20,000,000
– Profit = (3.50 − 2.50) × 110,231,000 − 20,000,000 = $90,231,000
– Break-even Price = 2.50 + (20,000,000 / 110,231,000) ≈ $2.68 per lb
– Sensitivity: each $0.10 change in price → profit change ≈ $11.02 million
– Use the same method for chemicals, timber, oil, etc., matching units consistently.
5. Review reserves, resource classification and life of mine
– Understand reserve categories: “proven” and “probable” reserves are the highest confidence estimates; resources are less certain.
– Compute life of mine (LoM) = Proven + Probable reserves / Annual production. Short LoM may mean earlier need for costly exploration or acquisitions.
6. Examine capital intensity and capital expenditures (capex)
– Basic materials businesses are often capital intensive. Check planned greenfield projects, sustaining capex, and expansion capex.
– Look for funding sources: free cash flow, operating cash, debt issuance, equity dilution. High future capex with weak cash generation is a red flag.
7. Check balance sheet and leverage metrics
– Key ratios: Net debt / EBITDA, Interest coverage (EBIT / Interest expense), Debt / Equity.
– For cyclical businesses, assess liquidity buffers (cash, credit lines) to survive low-price periods.
8. Analyze hedging, contracts and downstream/upstream exposure
– Hedging: producers may lock prices via forwards/options. Hedging reduces price risk but can cap upside; check hedging book size and maturity.
– Long-term offtake contracts or integrated operations change exposure — a miner that owns a smelter has different risk than a pure-play producer.
9. Consider currency and macro risks
– Revenues may be in USD while costs are in local currency (or vice versa). Currency moves affect profitability.
– Inflation, interest rate cycles, and trade policy materially affect basic materials.
