Market capitalization, often called "market cap," represents the total market value of a company's outstanding shares.
It is widely used by investors because it provides a quick way to assess the size and value of a company.
Companies are often classified according to market cap:
| Company Size | Market Capitalization |
|---|---|
| Mega Cap | $200 Billion+ |
| Large Cap | $10 Billion+ |
