Summary
Market Capitalization, often called Market Cap, represents the total market value of a company’s outstanding shares. It shows how much the equity market currently values the company.
Market Cap is one of the most common measures of company size.
Why it matters
Market Cap helps investors compare companies by size and understand their position within the market. Larger companies are often viewed as more established, while smaller companies may offer higher growth potential but can also carry greater risk.
Market Cap is also used in several valuation ratios.
How it is calculated
Market Capitalization = Market Price × Number of Shares
How to read it
A higher Market Cap indicates a larger market value. A lower Market Cap indicates a smaller market value.
Market Cap should not be confused with company value including debt. For a broader measure, investors may also review Enterprise Value.
