Most people research a sector by reading whatever they happen to find first — a news article, a broker note, a thread. The result is a pile of facts with no shape, and no way to compare what they learned about cement with what they learned about banks. A checklist fixes that. Eight questions, always in the same order, produce eight answers that sit side by side across every sector you ever study.
This is the process, not a theory of it. You can run all eight points on a sector you have never looked at before in a single sitting, using only the annual report of two companies in it, a monthly data release, and the sector index chart. What follows is each question, what you are really asking underneath it, where the answer lives, and what a bad answer sounds like.
Why a fixed order beats a clever order
The order matters more than it looks. Each point feeds the next: you cannot judge pricing power until you know the cost stack, and you cannot pick a valuation multiple until you know how capital-hungry the business is. Jumping straight to valuation — which is where almost everyone starts — means choosing a multiple before you know whether it fits.
The second benefit is comparability. If you always ask the same eight questions, your notes on sugar and your notes on information technology (IT) services are structured identically, so you can hold them next to each other. Research that is not comparable is just reading.
The third benefit is that it exposes what you do not know. A blank line under point five is far more useful than a page of prose about points one and two.
The checklist at a glance
Print this, or keep it in a note. Every sector page you ever write should carry these eight headings. P&L below is the profit and loss statement — the part of the annual report showing revenue, costs and profit for the year.
| # | The question | Where to look | Red-flag answer |
|---|---|---|---|
| 1 | What does it sell, and to whom? | Annual report, segment note | Nobody can say it in one sentence |
| 2 | What makes revenue move? | Volume and realisation disclosure | Revenue only grows when prices spike |
| 3 | Where does the cost go? | Cost break-up in the P&L | One input is over half the cost |
| 4 | Who sets the price? | Margin stability against input swings | Margin collapses whenever input rises |
| 5 | Who regulates it? | Ministry and regulator releases | One order can rewrite the economics |
| 6 | How hungry is it for capital? | Balance sheet and cash flow statement | Growth always needs fresh debt |
| 7 | Which multiple fits? | Peer set and its own history | Only one multiple flatters it |
| 8 | What data moves it? | Monthly and quarterly calendar | No public number tracks the business |
Points 1 and 2: the product, the buyer, and what moves revenue
Point one sounds trivial and is not. Write, in one plain sentence, what the sector sells and who pays for it. "Cement companies sell bagged and bulk cement to housing builders, infrastructure contractors and individual home builders, mostly within a few hundred kilometres of the plant because freight is expensive." That sentence already contains the sector's most important constraint. If you cannot write it without hedging, you have found the real gap in your understanding.
Point two breaks revenue into its parts. Almost every sector's revenue is volume multiplied by realisation — how much they sold, times what they got per unit. Find out which of the two is actually driving growth, because a sector growing on volume is in a different position from one growing only because prices spiked.
- 1
What it sells, and to whom
Name the product, the buyer, and the geography. Note whether the buyer is a consumer, another business, or the government — because that decides how the sector gets paid and how long it waits.
- 2
The revenue drivers
Split revenue into volume and realisation. Then ask what makes each of them move: monsoon, government capital expenditure, festive demand, overseas client budgets, interest rates, a replacement cycle.
Pro tip — Government-funded sectors have a hidden fourth question: how quickly does the customer pay? A sector with a full order book and a receivables problem is not the same investment as one with a full order book and prompt payment.
Points 3 and 4: the cost stack, and who holds pricing power
Point three finds the biggest line in the cost break-up. In most sectors, one or two inputs dominate and everything else is noise. Once you know the largest input, you know which external price to track — and that single number will explain more quarterly margin surprises than any amount of company commentary.
Point four is the harder and more valuable question: when that input cost rises, who eats it? A sector with pricing power passes the increase to its customer within a quarter or two and its margin recovers. A sector without it absorbs the increase and reports a margin collapse. The way to test this without a database is simple — look at what happened to gross margin in a period when the main input clearly rose sharply.
| Sector | The dominant input cost | So the number to watch is |
|---|---|---|
| Cement | Power, fuel and freight | Pet coke and diesel prices |
| Sugar mills | Sugarcane bought from farmers | The FRP and state cane price |
| Airlines | Aviation turbine fuel | ATF price and the rupee |
| Paints | Crude-linked chemicals and pigments | Crude oil and titanium dioxide |
| IT services | Employee salaries | Wage hikes, attrition, utilisation |
| Banks | Interest paid on deposits | Cost of funds against loan yield |
FRP is the Fair and Remunerative Price — the cane price set centrally for sugar mills, which several states then top up with their own State Advised Price. ATF is aviation turbine fuel, the jet fuel that is an airline's single largest cost. Utilisation, in IT services, is the share of billable hours actually billed.
Notice what the right-hand column has in common: every one of those is a publicly available price or policy number that moves before the quarterly result does. That is the whole point of finding the dominant input — it converts a company you cannot see inside into something you can track from outside.
Watch out — Pricing power is a property of the position in the chain, not of the brand. A supplier with one large customer, a commodity producer selling an undifferentiated product, and a business whose price is set by a regulator all lack it — no matter how well known the company is.
Points 5 and 6: the regulator, and the shape of the balance sheet
Point five asks who can change the rules, and which levers they hold. In India, several sectors are effectively policy instruments: banking through the Reserve Bank of India (RBI), telecom and power through their respective regulators and ministries, pharmaceuticals through price control on essential medicines, sugar and fertiliser through direct price and quota decisions. Naming the regulator is not enough — name the specific levers, because those are the events you will need to watch for.
Point six is about how the business consumes cash. Two questions do most of the work: how much capital does it take to add one unit of capacity, and how long is the gap between paying suppliers and being paid by customers. That gap is the working capital cycle, and it is why two sectors with the same reported profit can have completely different cash positions.
- Policy levers
- The concrete tools a regulator can pull — interest rates and lending norms, import and export duties, price caps, quotas, licence terms, subsidy rates, blending or local-content mandates.
- Capital intensity
- How much money must be spent up front to add capacity. A cement plant or a steel mill is highly capital-intensive; a services business is not. High intensity means long lead times and long stretches where spending has begun but revenue has not.
- Working capital cycle
- Roughly: days of inventory held, plus days customers take to pay, minus days the business takes to pay suppliers. A long cycle means growth itself consumes cash, so a fast-growing company can be profitable and still short of money.
- Operating leverage
- The share of costs that are fixed. Where fixed costs are high, a small rise in volumes lifts profit sharply — and a small fall in volumes cuts it just as sharply in the other direction.
Points 7 and 8: the right multiple, and the calendar
Point seven picks the valuation lens, and the answer follows directly from points three to six. The shape of the business decides which multiple carries information; using the wrong one produces confident nonsense.
| Shape of the business | Multiple that usually fits | Why |
|---|---|---|
| Lends money | Price to book value (P/B) | The balance sheet is the product |
| Asset-heavy with debt | EV/EBITDA | It ignores capital structure |
| Deep cyclical | EV per tonne or EV/EBITDA | Earnings vanish at the trough |
| Steady consumer brand | Price to earnings (P/E) | Earnings are relatively stable |
| Long-gestation projects | Order book and cash flow | Profit arrives years after the spend |
EV is enterprise value — market capitalisation plus debt, minus cash — so it values the whole business rather than only the equity. EBITDA is earnings before interest, tax, depreciation and amortisation, an approximation of operating profit before financing and accounting choices. Together, EV/EBITDA lets you compare two companies with very different debt levels, which a price-to-earnings ratio cannot do.
Point eight is the least glamorous and the most useful. Every sector has a rhythm of public data: monthly volume or dispatch numbers, quarterly results, policy meeting dates, an annual budget, an occasional tariff order. Write the calendar down once and you stop being surprised. It also tells you when your view can actually be tested — a thesis with no scheduled data point to check it against is not a thesis, it is a mood.
Example — A worked point eight for autos: monthly wholesale dispatch numbers early each month, quarterly results, the monsoon's progress for rural demand, fuel prices, and any change in the goods and services tax (GST) rate or import duty on vehicles and components.
Running all eight in one sitting
This takes an evening, not a month. The goal of the first pass is not a valuation — it is a one-page map you can improve later.
The first-pass routine
- Pick the two largest listed companies in the sector and download their latest annual reports.
- Read only the management discussion section and the segment note — that covers points 1, 2 and 5 faster than anything else.
- Open the profit and loss statement and rank the cost lines by size. The top line is your point 3 answer.
- Compare gross margin across four to six quarters against the price of that dominant input. That is your point 4 answer.
- From the balance sheet, note debt, the capital spent on adding capacity, and inventory plus receivable days. That is point 6.
- Use the shape you have just described to choose the multiple, then check the sector's own history on it rather than the market's average.
- List every scheduled data release and policy date the sector responds to, with its usual date in the month.
- Last, open the sector index chart — the level it is holding or losing, the volume behind the last move, and whether the retest held.
What a red flag actually looks like
A red-flag answer is not a reason to conclude anything about a company. It is a signal that this sector needs more work than the last one, and that any company inside it deserves harder questions.
The strongest red flags are the ones where two points contradict each other. Point two says revenue is growing fast; point six says the working capital cycle is stretching. That combination — growth that is not converting to cash — is the single most common warning the checklist surfaces, and it is invisible if you only look at the revenue line. Another: point four says the sector has no pricing power, and point six says it is capital-intensive with high fixed costs. That pair means margin swings will be violent in both directions.
The other kind of red flag is silence. If point eight has no answer — no monthly number, no regulator disclosure, nothing public that tracks demand — then you have no way to test whether you are right between quarterly results. That is a real limitation, not a small one.
Watch out — Never treat a full set of green answers as a conclusion. A healthy sector still contains weak balance sheets, and this checklist deliberately says nothing about any individual company's governance, promoter conduct or accounting quality.
What the checklist will not do for you
It will not price anything. Eight good answers tell you how a sector makes and loses money; they do not tell you what a fair value is for a specific business in it, and they cannot.
It will not time anything. A sector's fundamentals can improve for several quarters before the stocks reflect it, and prices frequently move ahead of the data in the other direction. The checklist tells you what to watch; the chart tells you what the market is currently doing with that information, and the two often disagree for long stretches.
And it will not settle the difference between two competitors. Point six catches balance-sheet shape, but leverage, contract structure, capacity mix, management quality and accounting conservatism are company-level questions that a sector-level pass is not designed to answer. Finish the eight points, then start the company work with a much better set of questions than you had before.
Key points
Pro tip — Keep one page per sector with the same eight headings and never delete an old answer — write the new one below it with the date. After a few quarters, the page shows you how the sector's economics are actually changing, which is information no single snapshot can give you.
Warning — A red-flag answer at any point is a prompt for more work, not a conclusion about any company. Sectors with difficult economics still contain well-run businesses, and sectors with easy economics still contain badly run ones — the checklist maps the terrain, it does not grade the participants.
Frequently asked questions
How long does the 8-point sector checklist take the first time?
A first pass takes an evening if you limit yourself to two annual reports, the profit and loss statement, the balance sheet and one sector index chart. The aim of the first pass is a one-page map, not a valuation. Depth comes from repeating the same eight questions each quarter and watching which answers change.
Where do I find a sector's cost break-up?
The profit and loss statement in any annual report lists cost lines separately — raw materials, employee benefits, power and fuel, freight, finance costs and so on. Rank them by size and the largest one or two are the sector's dominant inputs. The management discussion section usually names the specific commodity or input behind that line, which is what you then track externally.
How do I tell whether a sector has pricing power?
Find a period when the dominant input cost clearly rose sharply, then look at what happened to gross margin over the following two or three quarters. A sector with pricing power passes the increase on and margin recovers. A sector without it absorbs the increase and margin stays compressed until the input falls again. Position in the value chain explains the result more reliably than brand strength does.
What is the difference between capital intensity and the working capital cycle?
Capital intensity is how much money it takes to build capacity — the up-front cost of a plant or a network. The working capital cycle is how much cash is tied up running the business day to day: inventory days plus the days customers take to pay, minus the days the business takes to pay its suppliers. A sector can be low on one and high on the other, and each creates a different kind of cash pressure.
Why does the right valuation multiple change from sector to sector?
Because different multiples ignore different things. Price to earnings breaks down where earnings swing violently or where debt levels differ widely between peers. Price to book value suits lenders because their balance sheet is the product. EV/EBITDA — enterprise value against operating profit before interest, tax, depreciation and amortisation — lets you compare businesses carrying very different amounts of debt. The shape of the business, which points three to six establish, decides which lens carries information.
Which point matters most if I only have time for one?
Point three, the dominant input cost, gives the most information per minute spent, because it hands you a publicly available number that moves ahead of the quarterly result. Point eight is a close second, since without a data calendar you have no way to check whether your view is holding up between results.
Does the checklist work for a sector with no listed pure plays?
Partly. You can still answer points one to five from industry associations, ministry data and the segment disclosures of diversified companies that operate in it. Points six and seven are harder, because balance-sheet and valuation questions need a comparable listed peer set. When there is no clean peer set, treat the valuation answer as unresolved rather than forcing a multiple onto it.
