Comparing companies in the same sector
How to choose true peers, adjust for accounting differences and business mix, and present a fair comparison table of growth, returns, balance sheets and valuation.
In this lesson
- Choose peers based on business mix, customers, geography and size, not just the sector label.
- Identify accounting and reporting differences that distort comparisons.
- Build a comparison table of growth, profitability, returns, balance sheet strength and valuation.
- Explain differences between peers rather than simply ranking them.
Builds on
- Analysing financial statements in practiceA fair comparison uses multi-year figures built from each company's own filings.
- Comparing valuations with history and peersPeer valuation, introduced there, is one part of the comparison.

In simple terms
Comparing a company with its competitors shows whether its growth, profitability and valuation are unusual. But two companies in the "same sector" can sell different products to different customers in different places. A fair comparison starts by choosing true peers and making sure the numbers measure the same things.
Choosing true peers
Ask, for each candidate peer:
- What does it sell? A company selling decorative paints to households is different from one selling industrial coatings to factories.
- To whom? Consumers, businesses or governments.
- Where? Mostly in India, or largely abroad.
- How big, and at what stage? A young, fast-growing company and a mature leader may both be peers, but their numbers will differ for good reasons.
Segment data helps here, as the products and customers lesson explains. Sometimes the best peers are listed abroad, or are segments within larger groups.
Making the numbers comparable
Before comparing, check:
- Consolidated versus standalone figures.
- Financial year: most Indian companies use April to March, but some subsidiaries of foreign groups use other years.
- One-off items: remove exceptional gains and losses consistently.
- Accounting choices: treatment of leases, capitalised development costs, depreciation lives, and revenue recognition, as the Ind AS lesson discusses.
- Business mix: a company with a large low-margin trading business will look less profitable than a pure manufacturer.
A comparison table
Worked example: Three made-up paint companies
| Alpha Paints | Beta Paints | Gamma Coatings | |
|---|---|---|---|
| Main business | Decorative paints | Decorative paints | Mostly industrial coatings |
| Revenue growth, 5-year yearly average | 14% | 9% | 11% |
| Operating margin, 5-year average | 19% | 13% | 11% |
| Return on capital employed, 5-year average | 32% | 18% | 14% |
| Net debt ÷ operating profit before depreciation | Net cash | 0.5 | 2.0 |
| P/E ratio | 50 | 30 | 25 |
| EV/EBITDA | 32 | 18 | 14 |
Alpha's higher valuation comes with faster growth, higher margins, much higher returns on capital and no debt. Gamma is a different business, mostly industrial, so it is a weaker peer for Alpha and Beta. Whether Alpha's premium is enough, or too much, is a judgement about the future, explored in the valuation method lesson.
Use several years of figures, because one year can flatter or punish any company. Show medians and ranges, not just rankings.
Explaining differences
For each important difference, write the reason:
- Higher margins: brand, scale, product mix, distribution, or a temporary advantage?
- Higher returns on capital: less capital needed per rupee of sales, or higher margins? The ROCE lesson shows how to break it down.
- Faster growth: market share gains, new products, acquisitions, or a low base?
- Higher valuation: do growth, returns and risk justify it, as the peer valuation lesson discusses?
A comparison that explains is far more useful than one that ranks.
Why it matters
Peer comparison shows what is normal in an industry and what is exceptional. It helps you test claims of a competitive advantage, judge whether a valuation is unusual, and spot companies whose numbers look odd compared with everyone else's, which can be a red flag.
Limitations
No two companies are identical, and adjustments involve judgement. Peers can all be overvalued or undervalued at the same time, so relative cheapness is not absolute value. Small peer groups make medians unreliable.
Common mistakes
- Using the sector label to choose peers.
- Comparing standalone with consolidated figures.
- Comparing only the latest year.
- Calling a lower multiple "cheap" without explaining it.
Try it yourself
- For a company you are researching, list five possible peers and note what each sells, to whom and where.
- Keep the three closest and build the comparison table above using five-year averages.
- Write one sentence explaining each major difference.
- Note whether the valuation differences seem consistent with the differences in the businesses.
Key takeaways
- Companies with the same sector label can have very different businesses. Choose peers by what they actually sell, to whom, and where.
- Check that figures are comparable, such as consolidated with consolidated, the same financial year, and similar treatment of leases, exceptional items and capitalised costs.
- Compare several years of growth, margins and returns on capital, not just the latest year.
- Valuation differences often reflect real differences in growth, returns and risk. Explain them before calling one company cheap.
- Present ranges and medians, and note what each company does differently.

Terms used in this lesson
- Peer group
- A set of companies similar enough in products, customers, growth, returns and risk that their valuations can be compared.
- Return on capital employed
- Operating profit (EBIT) divided by the capital provided by shareholders and lenders together, a measure of business quality little affected by debt.
- EV/EBITDA
- Enterprise value divided by EBITDA, a valuation multiple that compares companies with different debt and depreciation fairly.
