How to analyse metal stocks
Steel, aluminium, zinc, copper and mining companies sell products whose prices are set largely by global demand and supply. Profit can multiply in a boom and vanish in a slump. So you judge these companies on how they survive the bad years, not on how they look in the good ones.
The numbers that matter
| Metric | What it tells you | What healthy looks like |
|---|---|---|
| EBITDA per tonne | Operating profit before depreciation for every tonne of metal sold. | Above peers across a full cycle, showing a cost advantage. |
| Cost position | Where the company’s cost of production stands against other producers. | In the lower part of the cost range, so it stays profitable when prices fall. |
| Raw-material security | How much of its iron ore, coal or bauxite the company gets from its own mines. | A large share of own supply, which smooths costs. |
| Net debt to EBITDA | Borrowings minus cash, compared with one year’s operating profit. | Low in normal years; check it on normal-year EBITDA, not boom-year EBITDA. |
| Capacity utilisation | How much of the plant’s capacity is actually used. | High and stable through the cycle. |
| Free cash flow | Cash from operations left after spending on plants and equipment. | Positive over a full cycle, used to cut debt in good years. |
Why a low P/E can be a trap
At the top of a metal cycle, profit is very high, so the P/E looks tiny. That is often when the price has the most room to fall. At the bottom, profit is low or negative, so the P/E looks huge or cannot be calculated. The cyclicals lesson covers this in detail.
A better habit is to estimate what the company earns in a normal year, somewhere between boom and bust, and judge the price against that.
Global prices drive the story
Metal prices depend on demand from construction, cars and machinery around the world, and on how much big producing countries export. Indian companies cannot control these prices. Say steel prices fall by ₹5,000 a tonne. For a company selling 10 lakh tonnes, that is ₹500 crore less revenue, with almost the same costs.
Debt is the real danger
Metal plants are expensive, so companies often borrow to expand. In a boom, profits cover the interest easily. In a slump, the same debt can become a heavy burden. Companies that cut debt in good years usually survive bad ones better.
Red flags
- Large debt-funded expansion announced near the top of a price cycle.
- Net debt to EBITDA that looks fine only because of boom-year profit.
- Heavy dependence on bought-in raw materials whose prices can spike.
- Interest cover falling quickly as metal prices weaken.
- Promoter shares pledged against loans in a volatile sector.
Common beginner mistakes
- Buying because the P/E looks very low at the peak of a cycle.
- Extrapolating one strong year of profit into the future.
- Ignoring debt because current profit easily covers interest.
Common questions
Why do metal stocks have low P/E at the top of the cycle?
Profit is unusually high in a boom, which makes the P/E look small. When prices fall, profit drops fast and the low P/E turns out to have been misleading.
How do I analyse a steel company?
Look at EBITDA per tonne, cost position, raw-material security, capacity utilisation and net debt. Judge these on normal-year numbers, not boom-year ones.
What moves metal stock prices?
Mostly global metal prices, which depend on world demand and supply. Company costs, debt and expansion plans decide how well each one handles the swings.
