Market capitalization, or market cap, is a measure of the total value of a company’s outstanding shares. It is calculated by multiplying the total number of shares outstanding by the current market price of one share.
Formula
Market Cap = Total Number of Shares Outstanding x Current Market Price per Share
Example
If a company has 10 million shares outstanding and the current market price is $100 per share, the market capitalization would be:
Market Cap = 10,000,000 x $100 = $1,000,000,000

- Large-Cap: Companies with a market capitalization of $10 billion or more. These companies are typically well-established, stable, and have a strong market presence.
- Mid-Cap: Companies with a market capitalization between $2 billion and $10 billion. These companies are often in a growth phase, with a established market presence and a strong potential for expansion.
- Small-Cap: Companies with a market capitalization between $300 million and $2 billion. These companies are often in the early stages of growth, with a smaller market presence and higher potential for volatility.
- Micro-Cap: Companies with a market capitalization between $50 million and $300 million. These companies are often in the early stages of development, with a limited market presence and high potential for growth.
- Nano-Cap: Companies with a market capitalization below $50 million. These companies are often in the startup phase, with a limited market presence and high potential for growth.
