Most people pick stocks the way they pick restaurants — somebody mentioned it, it looked busy, the story sounded good. That works for dinner. For a portfolio, you need a process: a small set of questions you ask of every company, in the same order, before a single rupee moves. This guide gives you that process. None of it requires a finance degree; everything below is checkable for free on company filings or a screener such as screener.in. Companies are named only as worked examples from our researched June 2026 data — never as recommendations.
A share is a slice of a business. The question is never "will the stock go up?" — it is "is this a good business, run honestly, at a sensible price?" Answer those three and the stock tends to take care of itself over years, not weeks.
1. Revenue and profit growth — is the business actually getting bigger?
Start with the top line. Pull five years of sales and net profit from the P&L (screener.in shows "Compounded Sales Growth" and "Compounded Profit Growth" directly) and ask three questions:
- Pace. Revenue compounding at 10%+ a year comfortably outruns nominal GDP; below that, the company is treading water in a growing economy. As reference points from our researched data: Bharti Airtel has compounded profits at roughly 24% over five years on tariff repair, while smaller names like JK Paper (~34% three-year sales CAGR) and Gulf Oil Lubricants (~26%) show what genuine growth looks like outside the index.
- Quality. Profit should grow at least as fast as revenue. Sales up 15% with profits flat means margins are being sacrificed to buy growth — sustainable for a while, dangerous as a habit.
- Consistency. Steady 12% every year beats 40%-then-minus-10%. Check for one-off spikes from asset sales or "exceptional items" — strip them out before judging the trend.
2. ROE and ROCE — how hard does the company work its capital?
Return on equity (ROE) is net profit divided by shareholders' funds: what the business earns on the money owners have left inside it. Return on capital employed (ROCE) widens the lens to include debt, so it cannot be flattered by leverage. Together they answer the most important long-run question: does this company create wealth with the capital it retains, or merely accumulate it?
A practical quality bar is 15% or better on both, sustained for three to five years — clearly above fixed-deposit rates and the cost of capital. India's better franchises run far higher: our researched data cites ROCE of roughly 38% for ITC, 41% (with ~32% ROE) for Asian Paints, and an extraordinary ~64% for Coal India. Two cautions: a high ROE built on heavy debt is fragile (always read ROE next to leverage), and for banks and NBFCs, ROCE is not meaningful — judge lenders on ROE, ROA and asset quality (HDFC Bank's consistently low NPAs are the kind of marker to look for) instead.
3. Debt — will the balance sheet survive a bad year?
Growth and returns mean little if a downturn hands the company to its lenders. Three quick checks for non-financial companies:
- Debt-to-equity below ~0.5 is comfortable; above 1 demands a very good explanation (regulated utilities and capital-intensive infra sometimes have one).
- Interest coverage above 4x — operating profit at least four times interest cost — means a 30–40% earnings dip still services the debt. Near-debt-free businesses, like cable-maker Polycab in our researched midcap data, simply skip this entire category of risk.
- Promoter pledging near zero. When promoters borrow against their own shares, a falling stock price can trigger forced selling that feeds on itself. The shareholding-pattern filings disclose pledge percentages every quarter; treat anything beyond a few percent as a serious warning.
4. Moats — what stops competitors from eating the returns?
High returns on capital attract competition; a moat is whatever stops that competition from succeeding. If you cannot name the moat in one sentence, assume there isn't one. The varieties you will actually meet in India:
- Brands with pricing power — customers pay up without comparison shopping (think of Royal Enfield's grip on mid-size motorcycles, reflected in Eicher's premium economics).
- Distribution depth — Asian Paints' dealer network and supply chain, built over decades, is why challengers with deep pockets still struggle to dent it.
- Switching costs — banks and IT vendors are painful to leave; deposits and multi-year contracts stick.
- Regulatory position or monopoly assets — HAL's status as India's sole military aircraft builder, or GAIL's national gas pipeline grid, cannot be replicated by a startup with funding.
- Low-cost production — Coal India's scale lets it earn outsized returns at prices that would sink smaller miners.
Evidence of a moat is quantitative, not rhetorical: stable or rising market share, gross margins that hold through downturns, and ROCE that stays high for a decade. A "story" with falling margins is just a story.
5. Valuation — P/E against the sector, not the universe
The price-to-earnings ratio — price divided by earnings per share — tells you how many rupees you pay for one rupee of annual profit. Its single biggest misuse is comparing across sectors. IT services, paints and PSU banks carry structurally different multiples because their growth, capital intensity and risk differ. The discipline is to compare a stock against its own five-year average and its sector peers, then ask why the gap exists. The dispersion in our researched large-cap data makes the point vividly:

Read the table the right way: TCS at ~15x after a -38% year is not automatically "cheap", and Asian Paints at ~58x is not automatically "expensive" — the market is pricing weak IT demand into one and four decades of compounding into the other. Your job is to judge whether that embedded expectation is reasonable. Three supporting tools help: PEG (P/E relative to growth — a 40x multiple with 25% growth can be saner than 15x with zero growth), price-to-book for banks and lenders where earnings are cyclical, and dividend yield as a floor check for mature cash generators. If you want to sanity-check what a return assumption implies, the free CAGR calculator makes the arithmetic honest.
6. Red flags — the cheap screen that saves the most money
Avoiding disasters matters more than finding winners. Walk away, or dig much deeper, when you see:
- Auditor resignations or qualified opinions. Auditors rarely quit healthy companies. Treat a mid-tenure resignation as a fire alarm.
- Receivables growing faster than sales. Booking revenue the company cannot collect is the oldest trick in aggressive accounting.
- Profits without cash. Over five years, cumulative operating cash flow should roughly track cumulative net profit. A persistent gap means paper earnings.
- Dividend payouts above 100% of earnings. A headline yield can mask an unsustainable payout: our researched dividend data flags Vedanta's ~14% yield as funded by a payout near 158% of earnings, tied to its parent's deleveraging needs — the yield is real today and unpromised tomorrow.
- Serial equity dilution. Frequent QIPs, warrants and ESOP floods mean your slice of the business shrinks every year; check the share-count trend.
- Heavy related-party transactions — sales, loans or asset purchases routed through promoter-owned entities.
- Falling promoter holding plus rising pledging — the people who know the business best reducing exposure while borrowing against the rest.
- Margins wildly above every peer with no structural explanation. Sometimes it is a moat; more often it is accounting.
The 10-point checklist
Run every candidate through this table. A genuine pass on eight or more puts a stock on your watchlist — it is still not a buy signal, just permission to study the annual report properly.

From checklist to portfolio
Process beats prediction, but only if you apply it consistently: practise on a fixed study set — our large-cap, dividend and small-cap lists carry the raw numbers and theses to interrogate — write one paragraph on why you would own each passing stock, size positions so no single mistake can hurt you badly (10–20 holdings is plenty), and re-run the checklist on results day, not on red candles. If the mechanics of actually placing the order are still new, the companion guide on how to buy shares in India closes the loop.
