What is Market Cap? Market Capitalization Explained

Market capitalization, or market cap, is the overall value of all a company's shares. Market cap matters because it helps investors see how big one company is compared to another.

To find it, you multiply the price of one share by the total number of shares. For instance, if a company has 20 million shares priced at US$50 each, its market cap would be US$1 billion.
