07.3 · Cyclicals & commodities¶
Why this matters: steel, cement, metals, chemicals, sugar, shipping, refining — a large part of the Indian market earns its profit in bursts. Valuing a cyclical on last year's earnings is how investors buy at the top (when the P/E looks lowest) and sell at the bottom (when it looks highest or infinite). The tools here — normalised earnings, mid-cycle margins, EV per tonne, replacement cost, the cost curve — exist to see through the cycle, and the trader's instinct for regimes is an advantage.
Learning objectives — after this lesson you can:
- Explain the P/E paradox for cyclicals and why trailing multiples invert their usual meaning.
- Build normalised (mid-cycle) earnings from a through-cycle margin or EBITDA-per-unit history.
- Use P/B, EV/replacement cost and EV/tonne (or EV/MW, EV/room) at cycle troughs.
- Read a cost curve and identify the marginal producer that sets the price.
- Build a commodity price deck and translate it into earnings sensitivity.
- Apply the toolkit to a fictional steel company and know where to check the real Indian names.

1. What makes a business cyclical¶
Earnings are cyclical when demand swings (autos, capital goods, housing) and/or price swings (commodities: steel, aluminium, crude, sugar, chemicals) meet high fixed costs and long-lived capacity (operating leverage, 04.2) and lagged supply (the capital cycle, 05.4). Price-takers in commodities are the purest case: the product is identical everywhere, so profit is set by the gap between a global price and the company's cost, and both move.
The consequences for analysis:
- Any single year's earnings is a draw from a wide distribution, not an estimate of "earning power".
- Margins mean-revert violently; the reversion is the thesis, not the noise.
- The balance sheet must survive the trough; leverage that looks modest at the peak is lethal at the bottom.
- The right multiples are the ones anchored to things that do not cycle: book value, capacity, replacement cost, normalised earnings.
2. The P/E paradox¶
At the top of the cycle, earnings are at their highest and the market — knowing they will fall — pays a low multiple: the stock looks cheapest exactly when it is most dangerous. At the bottom, earnings are minimal or negative and the P/E is enormous or meaningless: the stock looks most expensive when it is cheapest. The old rule: buy cyclicals at high P/Es, sell them at low P/Es.
Narmada Steel (fictional): 7 MT capacity, market cap ₹30,000 Cr, net debt ₹12,000 Cr, equity ₹20,000 Cr.
| FY | EBITDA/tonne (₹) | Volume (MT) | EBITDA (₹ Cr) | PAT (₹ Cr) | P/E at ₹30,000 Cr mcap |
|---|---|---|---|---|---|
| FY17 | 3,200 | 4.0 | 1,280 | (720) | n/m |
| FY18 | 4,500 | 4.2 | 1,890 | (110) | n/m |
| FY19 | 6,800 | 4.5 | 3,060 | 832 | 36x |
| FY20 | 9,500 | 4.8 | 4,560 | 1,920 | 16x |
| FY21 | 12,500 | 5.0 | 6,250 | 3,188 | 9x |
| FY22 (peak) | 15,000 | 5.5 | 8,250 | 4,688 | 6.4x |
| FY23 | 7,000 | 5.8 | 4,060 | 1,395 | 22x |
| FY24 (trough) | 4,200 | 6.0 | 2,520 | 15 | 2,000x |
| FY25 | 5,500 | 6.2 | 3,410 | 570 | 53x |
| FY26 | 8,000 | 6.5 | 5,200 | 1,875 | 16x |
(EBITDA = ₹/t × MT ÷ 10 gives ₹ Cr; PAT = (EBITDA − D&A − interest) × 0.75 with D&A rising from ₹900 to ₹1,800 Cr as capacity was added and interest ₹650–1,100 Cr.) At the FY22 peak the stock was "cheap" at 6.4x; two years later earnings had fallen 99.7%. An investor who bought the 6.4x P/E bought the top.
3. Normalised earnings¶
Normalised (mid-cycle) earnings replace the current year's margin with a through-cycle average, holding current volume and cost structure:
Narmada: ten-year average EBITDA/tonne = ₹7,620 (median ₹6,900); at FY26 volume of 6.5 MT → normalised EBITDA ₹4,953 Cr; less D&A 1,800 and interest 900 → PBT 2,253 → normalised PAT ≈ ₹1,690 Cr; normalised P/E = 17.8x. FY26's actual (₹1,875 Cr PAT, 16x) is close to mid-cycle — neither peak nor trough — which is the useful conclusion: the stock is roughly fairly priced on through-cycle earnings, and a bet on it is a bet on the next phase of the cycle, not on cheapness.
Choices that matter:
- Which average? A full cycle (peak to peak or trough to trough), not "the last five years". Ten years usually spans one; check that it includes at least one bad year.
- Mean or median? The mean is pulled up by super-cycles (FY21–22 above); the median is more conservative. Report both.
- Has the structure changed? New capacity at lower cost, a captive mine, a tariff regime, China's export behaviour — any of these shifts the mid-cycle level. Normalise the unit economics, then adjust for known structural change, and say which.
- Volume is not the current year's either if capacity utilisation is cyclical (cement at 65% vs 85%).
Multiples on normalised earnings: EV/normalised EBITDA (Narmada: 42,000 / 4,953 = 8.5x) and P/normalised E are the cyclical analyst's working multiples; compare with the company's own through-cycle history and with peers at the same cycle stage.
4. Asset-anchored multiples at troughs¶
When earnings are near zero, value the assets:
| Multiple | Narmada | Reading |
|---|---|---|
| P/B | 30,000 / 20,000 = 1.5x | Through a cycle, commodity producers oscillate roughly between 0.5–0.8x book at troughs and 2–3x at peaks (India-specific bands differ by sector — verify on Screener for steel/cement). 1.5x is mid-range, consistent with the normalised-earnings read |
| EV / tonne of capacity | (30,000 + 12,000) / 7 MT = ₹6,000 Cr/MT | Compare with replacement cost: a greenfield integrated steel plant in India has cost roughly ₹7,000–9,000 Cr per MT in recent projects (verify against announced capex — e.g., recent JSW/Tata/AM-NS expansions); at ₹6,000 Cr/MT the market values Narmada's capacity below what it would cost to build, a mild trough signal |
| EV / replacement cost | ≈ 0.7–0.85x | Below 1x: no rational entrant builds new capacity at these prices → supply tightens → prices recover (the capital-cycle mechanism). Above 1.5x: everyone builds |
| EV / EBITDA (peak) | 42,000 / 8,250 = 5.1x | The "cheap" peak multiple — a warning, not an invitation |
For cement the same logic runs on EV/tonne (₹ Cr per MT of capacity) against a replacement cost that has risen with land and limestone costs; for power EV/MW; hotels EV/room; shipping EV vs fleet scrap/newbuild value; oil & gas EV/boe of reserves. In every case the question is the same: is the market pricing this capacity below what it would cost to replace, and if so, why?
5. The cost curve and the marginal producer¶
For a commodity, price is set where demand meets the cost curve — producers ranked from lowest to highest cash cost. In a downturn, price falls to the cash cost of the marginal producer needed to meet demand; the high-cost tail loses money and closes; the low-cost producers keep earning. In an upturn, price rises until the highest-cost producer needed is profitable.

B --> C[High-cost / marginal<br/>bought-in ore, old plants<br/>₹46k/t]
D[Demand] -.->|sets price near<br/>marginal cash cost| C
What this means for a stock:
- Position on the curve is the moat. A first-quartile producer (captive raw materials, scale, logistics) earns through the cycle; a fourth-quartile producer earns only at peaks and may not survive troughs. Coal India and NMDC sit low on their curves because of reserve quality; some Indian steelmakers moved down the curve by acquiring captive iron ore mines in the 2020 auctions (verify).
- Price floors are analysable. If the marginal producer's cash cost is ₹46k/t and the price is ₹44k/t, capacity is closing and the floor is near; if the price is ₹60k/t, the whole curve is profitable and capacity is coming.
- China sets many curves. For steel, aluminium and chemicals, Chinese capacity and export policy define the global marginal producer; Indian tariffs (safeguard duties, anti-dumping) move the domestic price relative to it. A view on Chinese exports is a view on Indian steel margins.
6. Price decks and sensitivity¶
A price deck is the set of commodity price assumptions a model uses by year. Build it from forward curves where they exist (LME for base metals, Brent), broker/consultant consensus where they don't (steel, cement realisation), and always show the sensitivity:
Narmada: a ₹1,000/t change in realisation on 6.5 MT with ~15% of it absorbed by cost linkages (input prices move with output prices) changes EBITDA by ≈ 1,000 × 6.5 / 10 × 0.85 = ₹553 Cr, or ~11% of FY26 EBITDA and ~22% of PAT (operating and financial leverage stacked). Present the sensitivity per ₹1,000/t, per $10/t or per 1% of price, and show what price the market is implying (a reverse DCF on the price deck — 06.6).
7. Indian sectors and where to look¶
| Sector | Cycle driver | Unit metric | Anchor multiple | Representative listed names (for study; verify facts) |
|---|---|---|---|---|
| Steel | Global price (China), domestic demand, iron ore/coking coal | EBITDA/tonne; cash cost/tonne | EV/tonne; P/B | Tata Steel, JSW Steel, SAIL, Jindal Steel |
| Aluminium, zinc, copper | LME price, power cost, captive mines | EBITDA/tonne; cost curve position | EV/tonne; EV/EBITDA on LME deck | Hindalco, Vedanta, Hindustan Zinc, NALCO |
| Iron ore / coal mining | Reserve quality, government pricing, volumes | Realisation/tonne; cost/tonne | P/E on normalised; dividend yield (cash-rich PSUs) | NMDC, Coal India |
| Cement | Regional demand/supply, utilisation, fuel (petcoke/coal) | EBITDA/tonne; utilisation | EV/tonne | UltraTech, Ambuja, Shree, Dalmia |
| Refining & petrochemicals | GRMs, crack spreads, polymer margins | GRM $/bbl | EV/EBITDA on mid-cycle GRM | Reliance, IOC, BPCL, HPCL |
| Commodity chemicals | Chinese capacity, crude derivatives, capex waves (2021–24 specialty chemicals) | Spread over feedstock | EV/EBITDA normalised; P/B at troughs | Verify current names and cycle stage |
| Sugar | Cane pricing (FRP/SAP), ethanol policy, monsoon | Recovery %, realisation | P/B; EV/tonne of crushing | Regulated pricing dominates |
| Shipping, ports | Freight rates (Baltic indices), trade volumes | TCE $/day | EV vs fleet value; NAV | Verify |
| Autos, capital goods (demand cyclicals) | Interest rates, incomes, capex cycle | Volume, utilisation | Normalised P/E; mid-cycle margin | 08.5, 08.6 |
Trader's lens
Cyclicals are regime trades, and the multiple is the regime indicator read backwards: low trailing P/E = the market pricing a regime shift down; high P/E = pricing a shift up. The useful analogy is vol of vol — you are not trading the level of earnings but the change in the level, and the entry signals are the ones vol traders know: extremes relative to a long history, capacity (supply) behaviour, and positioning. Normalised earnings are the long-run mean; the capital cycle is the mean-reversion mechanism; the cost curve tells you where the floor is. Position sizing must respect that the floor is only approximate and the path to it can bankrupt the levered.
India notes
- Government pricing intrudes: coal (Coal India's notified prices and e-auction premia), iron ore (NMDC's monthly prices), sugar (FRP/SAP), ethanol, fertiliser (subsidy), fuel (OMC marketing margins). Model the policy as a driver, with a scenario for change.
- Duties move the domestic price relative to the global cost curve: safeguard duties on steel (2025), export duties (2022), anti-dumping on chemicals — check the current schedule for any sector you model.
- PSU miners and metals companies pay large dividends at cycle peaks; the dividend yield at the peak is not sustainable and should not anchor valuation.
Common mistakes
- Buying a cyclical because its trailing P/E is low.
- Normalising over a period that is all peak or all trough.
- Ignoring balance-sheet survival: the trough is where the equity option can expire worthless (06.7, Merton).
- Treating EV/tonne as a valuation rather than a cross-check (capacity ≠ cash).
- Forgetting that structural changes (captive mines, new low-cost capacity, tariffs) move the mid-cycle.
- Extrapolating a super-cycle (FY21–22) into "the new normal".

Check your understanding¶
- Narmada Steel's FY22 P/E was 6.4x and FY24's was ~2,000x. Which year was the better time to buy, and what metric would have said so?
Answer
FY24. EV/tonne (well below replacement cost), P/B (≈1x or below at the FY24 price, if the price had fallen with earnings), and normalised P/E (which uses ₹1,690 Cr of mid-cycle PAT, not ₹15 Cr) all pointed to a trough; the 2,000x trailing P/E was the paradox at work.- Compute Narmada's normalised PAT using the median EBITDA/tonne instead of the mean, and the normalised P/E.
Answer
Median ₹6,900/t × 6.5 MT ÷ 10 = ₹4,485 Cr EBITDA; PBT = 4,485 − 1,800 − 900 = 1,785; PAT ≈ 1,339; P/E ≈ 22.4x. The choice of mean vs median moves the normalised P/E from 17.8x to 22.4x — report the range.- Steel is at ₹52,000/t; the marginal producer's cash cost is ₹46,000/t; new capacity announcements have surged. What does the cost curve predict?
Answer
The whole curve is profitable, so capacity is being added; when it arrives, price falls toward the marginal cash cost (~₹46,000) or below it temporarily until high-cost capacity closes. Margins for mid-curve producers compress by ~₹6,000/t; only first-quartile producers keep earning well.- Why does a cyclical need a stronger balance sheet than a stable business with the same average profit?
Answer
Its cash flow is intermittent: debt service is fixed but EBITDA can fall 70% in a trough (Narmada FY22→FY24). Leverage that is 1.5x EBITDA at the peak becomes 5x at the trough, covenants trip, and the equity — a call option on the assets — can expire worthless before the cycle turns.- A cement company trades at EV/tonne of ₹4,500 Cr/MT while recent acquisitions were at ₹8,000–10,000 Cr/MT. List two reasons it might not be cheap.
Answer
Its capacity may be poorly located (high freight to markets), old and inefficient (high cost per tonne), or under-utilised in an oversupplied region; and acquisition prices include control premia and synergies a minority shareholder does not get. EV/tonne must be read with utilisation, cost and regional pricing.Go deeper¶
