Before investing in a stock, understand how the company earns money, whether revenue, profit and operating cash flow are improving, how much debt it carries, whether management treats minority shareholders fairly and whether the market price already assumes very high growth. No single ratio is enough; compare several years and relevant competitors.
Key points
- Start with the business model, not the share-price chart.
- Compare at least several years of revenue, margins, cash flow and debt.
- Read exchange filings, annual reports and auditor notes.
- Separate a good company from a good investment price.
Understand the business first
List the company’s major products, customers, geographies, competitive advantages and key costs. Identify what can cause sales or margins to rise and fall. If the business cannot be explained simply, avoid forming a strong view from ratios alone.
Read the three financial statements together
The profit-and-loss statement shows revenue and accounting profit, the balance sheet shows assets, liabilities and equity, and the cash-flow statement shows where cash came from and where it went. Profit growth without operating cash flow deserves investigation.
Check management, governance and valuation
Review promoter holding and pledging, related-party transactions, capital allocation, auditor remarks, dilution and major legal or regulatory issues. Then compare valuation with business quality, growth durability, balance-sheet risk and peers.
Worked Indian example
Suppose Company A reports 20% profit growth, but receivables rise much faster than sales and operating cash flow remains weak. Company B grows profit by only 12%, but converts most profit into cash and carries little debt. The faster headline growth of Company A does not automatically make it the safer or better investment.
Comparison table
| Area | Questions to ask | Possible warning sign |
|---|---|---|
| Business | How does it earn money? Is demand repeatable? | One customer, one product or unstable pricing |
| Profitability | Are sales, margins and EPS improving consistently? | One-off income driving profit |
| Cash flow | Does operating cash broadly support reported profit? | Persistent profit without cash |
| Balance sheet | Can the company comfortably service debt? | Rapid debt growth or refinancing dependence |
| Governance | Are disclosures and related-party dealings clear? | Pledging, frequent dilution or auditor concerns |
| Valuation | What growth is already priced in? | High multiple with weak or cyclical earnings |
Use the checklist as a research framework, not a mechanical stock-selection score.
Risks and limitations
- Historical financial statements cannot guarantee future performance.
- Accounting policies can make comparisons misleading.
- A strong business can still produce poor returns when bought at an excessive valuation.
- Sector cycles, regulation and disruption can change the investment case quickly.
Frequently asked questions
How many years of data should I check?
Five to ten years is useful where available, while also giving more weight to recent structural changes.
Should I buy only companies with zero debt?
No. Debt can be productive, but it should be appropriate for the business and supported by predictable cash flow.
Is rising profit enough?
No. Check cash flow, margins, debt, dilution, exceptional items and the quality of earnings.
Where should I get company information?
Use annual reports, audited results and official NSE/BSE corporate filings before relying on summaries.
