Market Capitalization explained

In stocks, typically you will hear analysts and investors speak of companies as "majors" or "juniors".

This terminology is usually derived from a company's market capitalization.

Market capitalization:

Market capitalization represents the public consensus on the value of a company's equity. A corporation, including all of its assets, may be freely bought and sold through purchases and sales of stock, which will determine the price of the company's shares. Its market capitalization is this share price multiplied by the number of shares in issue, providing a total value for the company's shares and thus for the company as a whole.

Essentially - it's the price of the stock of the company multiplied by its shares outstanding.
