Market capitalization

Market capitalization ("market cap") is a company's share price multiplied by its total number of shares outstanding — the market's current valuation of the whole business.

Why it's not just "price"

A ₹3,000 share and a ₹300 share tell you nothing about company size on their own — it depends entirely on how many shares exist. A company with 10 crore shares at ₹300 (₹3,000 crore market cap) is bigger than one with 10 lakh shares at ₹3,000 (₹300 crore market cap), despite the higher price tag on the second.

The rough size bands

India doesn't have one universal cutoff, but broadly: large-cap (the biggest, most established names — think Nifty 50 constituents), mid-cap (smaller, often faster-growing, more volatile), and small-cap (smallest, highest risk and potential reward, least liquid).

Why it matters for risk

Larger companies tend to be more stable — more analyst coverage, more liquidity, more resilience to a single bad quarter. Smaller companies can grow faster, but a single piece of bad news can move the price much more sharply, and it can be harder to sell a large position quickly without moving the price yourself.
