To compare stocks across banking, IT, metals and railways, use a consistent set of financial periods and reporting bases, then choose ratios that fit each company’s business. A bank’s capital adequacy and non-performing loans matter in ways that do not translate to a metals producer; a railway equipment maker may have a different financial profile from a railway operator. Ratios help organize the comparison, but they do not make unlike businesses directly comparable or amount to a buy recommendation.
This guide uses an India-oriented regulatory and disclosure context, drawing on Reserve Bank of India (RBI) and Securities and Exchange Board of India (SEBI) materials. The comparison principles are useful more broadly, but the regulatory and sector figures below describe India.
Start by making the comparison fair
Before comparing a ratio, check that the companies are being measured on the same basis. Otherwise, a difference may reflect the data you selected rather than a difference in business performance.
- Match the period. Compare the same fiscal year or the same trailing-period length. A valuation multiple also depends on the date of the share price used.
- Match the reporting scope. Compare consolidated statements with consolidated statements, or standalone with standalone. If the available figures do not match, flag the mismatch or separate the companies into comparable groups.
- Match currencies and definitions. Check units, accounting notes and the exact inputs behind adjusted measures such as EBITDA. The same ratio label does not guarantee that companies calculated it the same way.
- Separate business models. A broad industry label is not enough to make two companies peers. Identify what each company sells, how it earns revenue and what assets or financing its business requires.
SEBI’s listed-peer disclosure illustrates why inputs should be visible: it describes P/E using closing market price and diluted EPS for a specified year, and enterprise value using market capitalization plus net borrowings. Those are examples of a disclosed calculation basis, not a universal rule for every issuer. Treat P/E and enterprise-value measures as dated comparisons, not timeless company attributes.
#1 Best Overall
SEBI Investor describes fundamental analysis as examining a company’s financial statements, business model and economic and industry factors. Ratios are one part of that analysis, alongside the company’s disclosures and circumstances.
Build the comparison around six questions
| Comparison axis | What to examine | What it helps reveal |
|---|---|---|
| Growth | Revenue and earnings trends over matching periods | Whether the business is expanding, slowing or reporting uneven results |
| Profitability | Margins where meaningful, return measures and sector-specific profitability | How effectively the company turns its activity and assets into earnings |
| Financial resilience | Bank capital and asset quality; industrial-company leverage, liquidity and debt servicing | How well the balance sheet may withstand pressure |
| Cash generation and asset use | Cash-flow information and relevant asset-use measures disclosed by the company | Whether earnings are accompanied by cash generation and how the business uses its assets |
| Valuation | Dated P/E or enterprise-value measures with their definitions and earnings periods | How the market price relates to a defined earnings or business-value measure |
| Business and reporting comparability | Business model, geography, accounting scope and exceptional items | Whether a peer comparison is meaningful before interpreting the ratios |
These are comparison axes, not a scoring system. There is no universal set of weights or cutoffs established for the four industries.
Which ratios matter for each sector?
Banking: profitability, capital and asset quality
Banks are financial intermediaries. Industrial-company leverage and operating-margin comparisons can mislead when used alone. For banks, compare profitability relative to assets and equity, net interest margin (NIM), capital adequacy, and asset quality. Useful reported measures include return on assets (RoA), return on equity (RoE), NIM, capital to risk-weighted assets ratio (CRAR) or an equivalent capital-adequacy measure, gross and net non-performing asset (NPA) ratios, provision coverage and slippage.
RBI explanatory notes define RoA as net profit divided by total assets and RoE as net profit divided by capital plus reserves and surplus. NIM concerns interest earned less interest paid relative to assets, but the formulation and presentation can depend on the table. Check each bank’s stated calculation before comparing the figure.

| Measure | End-March 2023 | End-March 2024 |
|---|---|---|
| RoA | 1.2% | 1.2% |

| NIM | 3.7% | 3.3% |
| CRAR | 17.2% | 16.9% |
| Gross NPA ratio | 3.9% | 2.8% |
These are Indian banking-sector figures, not individual-bank results, current values for every bank, or regulatory minimums. Use a bank’s own dated disclosures for a stock comparison, and include the metric’s calculation basis.

Information technology: compare like-for-like business models
Begin with revenue growth, profitability, return measures, cash generation and valuation. Then use operating measures that fit the company’s actual services and revenue model, drawing those measures from company disclosures. Compare like-for-like IT peers and check whether figures are consolidated or standalone.
The sources cited here do not establish authoritative current IT-sector benchmarks or a universal IT-specific ratio set. Do not treat a generic ratio or an unrelated company’s result as a threshold for the sector.
Metals: account for the cycle, debt and cash generation
For metals companies, examine earnings and cash generation across the business cycle, alongside leverage, debt-servicing capacity, liquidity and asset use. A single period may not represent performance across changing business conditions, so interpret results with the company’s operating history and disclosures.
RBI’s sector-specific borrower framework covers iron and steel manufacturing and non-ferrous metals. It defines total debt/EBITDA, current ratio and debt-service coverage ratio as analytical measures. The framework was developed for resolution plans and has a borrower-resolution purpose; its measures are not automatic equity valuation cutoffs or universal stock-buying thresholds.
Railways: identify what the company actually does
First distinguish a railway operator from an infrastructure owner, equipment or rolling-stock maker, or supplier with railway exposure. These businesses can differ in assets, financing, revenue and cash-flow patterns. Use common measures for profitability, leverage, cash generation and valuation, then select additional operating measures from disclosures by the relevant companies.
The sources cited here do not establish a universal railway-specific ratio set for India. In particular, do not assume one operating measure suits every railway-linked company; determine whether it fits the company’s actual business and is defined consistently across peers.
Interpret ratios without false precision
Read multiples in context
A P/E or enterprise-value multiple is only as comparable as its price date, earnings period and calculation inputs. Check whether earnings are negative, whether a reported result includes unusual one-off items, or whether a recent capital issuance has changed the share count or balance sheet. Cyclical peaks and troughs can also make a single period a poor guide to a company’s broader performance. These conditions are reasons to qualify or avoid a simple multiple comparison, not prompts to apply an unsupported adjustment formula.
Do not treat a shared label as a shared formula
Inspect the notes behind adjusted EBITDA, sector-specific KPIs and other company-defined measures. A company may define an adjustment differently from a peer. If the definitions or reporting scope differ, state the difference rather than presenting the figures as directly interchangeable.
Use sector-appropriate balance-sheet measures
Do not mechanically compare a bank’s debt-to-equity ratio with a manufacturer’s. For banks, examine capital adequacy and asset quality alongside profitability. For industrial businesses, consider operating cash generation, leverage, liquidity and debt-service capacity.
Quick Recap
A practical peer-comparison workflow
- Define the peer group. Choose companies with sufficiently similar businesses, and note differences in geography or revenue mix.
- Set the measurement basis. Choose the fiscal period, consolidated or standalone reporting scope, currency and ratio definitions. Record the share-price date for market-based measures.
- Collect core measures. Compare growth, profitability, financial resilience, cash generation and valuation using matching periods and disclosed inputs.
- Add sector-specific measures. Use bank capital and asset-quality indicators for banks; for industrial businesses, assess leverage and debt servicing. For IT and railway-related companies, select operating measures that fit the specific business and are disclosed consistently.
- Review the notes and exceptions. Check for different formulas, negative earnings, one-off items, recent capital changes and cyclical conditions that complicate a simple comparison.
- State the limits of the comparison. Identify any mismatched reporting bases, missing disclosures or measures that are not comparable. Do not turn the resulting table into a recommendation without considering business, industry and economic context.
