Essential Market Insights

1Market Capitalization = Current Share Price × Total Number of Outstanding Shares.

2Share price alone is misleading — a ₹1,00,000 stock (MRF) can be smaller than an ₹800 stock (SBI) in terms of market cap.

3SEBI classifies: Large-Cap = Top 100 companies, Mid-Cap = 101st to 250th, Small-Cap = 251st onwards.

4Large-caps offer stability with moderate growth; Small-caps offer explosive growth potential with very high risk.

5A small-cap company can grow into a large-cap over time (e.g., Bajaj Finance).

Key Formula

Market Capitalization = Current Share Price × Total Number of Outstanding Shares

Worked Calculation Example:

• Company: Example Corp

• Share Price: ₹500

• Outstanding Shares: 10 Crore

• Market Cap: ₹5,000 Crore (Mid-Cap)

1. What is Market Capitalization?

Market Capitalization (market cap) measures the total equity value of a publicly traded company. It is calculated by multiplying a company's current market share price by its total number of outstanding shares.

Market cap allows investors to evaluate the true corporate size of a business rather than judging size by share price alone.

2. SEBI Categorization Framework

To protect mutual fund investors, SEBI established a standardized market cap classification:

1. Large-Cap: Top 100 companies ranked by market capitalization (established industry leaders like Reliance, TCS, HDFC Bank).

2. Mid-Cap: Companies ranked 101st through 250th by market cap (fast-growing medium-sized enterprises).

3. Small-Cap: Companies ranked 251st and beyond (early-stage or emerging businesses with high volatility).
