Stock market basics: how to research an Indian stock
What to look at when you research a listed company — and, just as important, the limits of each number. This is general education, not advice on any specific stock.
Updated 9 September 2026
A share is a small ownership stake in a company. In India most shares are bought and sold on two exchanges, the NSE and the BSE. A company’s shares get onto an exchange through an IPO; after that they trade freely and the price moves with supply and demand.
The parts of a research page
Platform’s stock pages are organised the same way for every company, so you always know where to look:
- Profile — what the business actually does, its sector and industry. Start here. A number means little until you know the business behind it.
- Price & volume — the current price, the day’s range and how many shares changed hands. Price alone tells you almost nothing about value — a “₹50 stock” is not cheaper than a “₹5,000 stock”.
- Financial performance — revenue, operating profit, net profit, margins, debt and cash flow, over several years and quarters. Look for the trend and whether profit turns into actual cash.
- Valuation — ratios like P/E (price ÷ per-share earnings) and P/B (price ÷ per-share book value) that compare the price to the fundamentals. A ratio is only useful next to something — the company’s own history, or its peers. On a loss-making company a P/E is “not meaningful”, not zero.
- Peer comparison — the same metrics for similar companies, on the same period and units. This is where a valuation number gets its context.
- Ownership — how much the promoters, institutions and public hold, and whether promoter shares are pledged (borrowed against). Big changes here are worth understanding.
- Corporate events — results dates, dividends, bonus issues, splits and board meetings, from exchange filings.
Reading the data honestly
Every figure on a Platform stock page is labelled with where it came from and how fresh it is. If we don’t have a reliable value, the page says “not yet available” — it does not show a zero, and it does not treat a gap as good news or bad news. If two sources disagree, the page shows both rather than silently picking one.
What research cannot do
No amount of reading tells you what a share price will do next. Research lowers the chance of an obvious mistake and helps you understand what you own — that is all. Be wary of anyone promising “multibagger”, “sure-shot” or “guaranteed” returns; Platform never uses that language and gives no buy/sell/hold calls.
Before you act
- Read the company’s own annual report and latest results — not just summaries.
- Understand how the company makes money and what could go wrong.
- Only invest money you will not need for several years.
- If you want personal advice, speak to a SEBI-registered investment adviser. Platform is an information service, not an adviser.
