Market Capitalization

Market Capitalization, or Market Cap, is the total value of a company’s shares on the stock market.

Think of it like this:
If a company was a pizza, and each slice (share) had a price, market cap is the price of the whole pizza.

Simple Definition:

Market Capitalization = Share Price × Total Number of Shares

It tells you how much the company is worth in the eyes of the market.

How to Calculate Market Capitalization?

Here’s the basic formula:

Market Cap = Current Share Price × Total Outstanding Shares

Example:

Let’s say:

  • A company’s share price = ₹500
  • Total outstanding shares = 10,00,000

Market Cap = ₹500 × 10,00,000 = ₹50 crore

This means the company is worth ₹50 crore in the stock market.

Types of Market Capitalization

Companies are often classified into three main categories:

  1. Large Cap
    • Market Cap: ₹20,000 crore or more
    • Examples: Reliance, TCS
    • Stable and less risky
  2. Mid Cap
    • Market Cap: ₹5,000 crore to ₹20,000 crore
    • Examples: Tata Power, L&T Finance
    • Balanced risk and growth
  3. Small Cap
    • Market Cap: Below ₹5,000 crore
    • Examples: Brightcom, HFCL
    • Higher risk, higher return potential

Why is Market Cap Important?

  • Helps investors compare companies
  • Shows the size and stability of a company
  • Used to create index groups (like Nifty 50 or Sensex)
  • Helps in portfolio diversification
  • Gives a sense of risk level — large caps are safer, small caps are more volatile

Limitations of Market Cap

  • Doesn’t show the company’s real value (intrinsic worth)
  • Doesn’t consider debt or assets
  • Share prices can fluctuate daily, affecting the cap
