Stock Market Cap Checker
Is your stock Large, Mid, or Small Cap? Check the official ranking of 5,000+ Indian stocks based on the latest AMFI classification.
Why Use the Stock Market Cap Checker?
Understanding the market capitalization of your stocks is not just about labels—it's about risk management. In the Indian stock market, SEBI (Securities and Exchange Board of India) has strict definitions that dictate how mutual funds can invest your money.
Institutional Shifts
When a stock's category changes, it often prompts rebalancing by mutual funds whose mandates are tied to specific AMFI market-cap buckets.
Portfolio Balance
Too much exposure to Small Cap stocks can lead to extreme volatility. This tool helps you see the "true weight" of your portfolio exposure instantly.
Understanding Market Cap Buckets
In the Indian equity ecosystem, the AMFI ranking is a mechanical classification used strictly for the purpose of defining investment universes for different schemes. Large Cap stocks (Rank 1-100) are generally considered the most liquid and tracked entities in the market.
The Semi-Annual Reclassification
Every 6 months (January and July), AMFI releases the updated categorization based on average market cap. A shift from one category to another (e.g., Mid to Large) may lead to institutional rebalancing as mutual funds realign their portfolios with the new regulatory definitions.

Frequently Asked Questions

We use the official Average Market Capitalization data released by the Association of Mutual Funds in India (AMFI).
Which list is currently active?
The current list is based on the average market capitalization data from July 1 to December 31, 2025. This list is used by all Indian mutual funds to rebalance their portfolios in early 2026.
What is the difference between Large Cap and Mid Cap?
Large cap stocks are generally more stable, established companies (Rank 1-100). Mid cap stocks (Rank 101-250) occupy the middle ground with higher growth potential but more risk than large caps.
