Stock basics
Large cap vs mid cap vs small cap
How market-cap buckets differ in risk, liquidity, and what “fundamentally sound” usually looks like in each.
Market capitalisation (market cap) is roughly:
Share price × total shares
It is a size label for the market’s valuation of the company — not a quality certificate.
The three buckets (intuition)
| Bucket | Typical feel | What usually matters more |
|---|---|---|
| Large cap | More researched, often more liquid | Business quality + valuation discipline |
| Mid cap | Growth + volatility mix | Execution consistency, balance sheet |
| Small cap | Higher uncertainty | Governance, liquidity, survival risk |
Exact official cutoffs change over time (exchanges/AMFI revise lists). Learn the behavior, not only the label.
Large caps — what to see / not see
See: durable franchise, cash generation, governance track record, cycle position.
Don’t assume: “Large cap = safe forever.” Even giants can over-earn at cycle peaks.
Mid caps — what to see / not see
See: whether growth is funded by operations or constant dilution/debt.
Don’t overweight: one strong year of profit without cash confirmation.
Small caps — what to see / not see
See: promoter integrity, disclosure quality, related-party risk, trading liquidity.
Don’t ignore: you may not exit easily when you want; spreads and gaps can be brutal.
A practical rule
Size tells you about ecosystem risk (liquidity, coverage, failure rates).
Fundamentals tell you about business quality.
Valuation tells you about what you pay.
You need all three.
