MARKET CAPITALIZATION
Back to GlossaryDefinition
The total market value of a company’s outstanding shares (price × shares outstanding).
Summary
Market capitalization (market cap) represents the total dollar value of all a company's shares in the stock market. It's calculated by multiplying the current stock price by the total number of shares available for trading. Market cap helps investors understand a company's size and compare it to other companies. For example, if a company has 1 million shares trading at $50 each, its market cap is $50 million. Companies are often categorized as large-cap (over $10 billion), mid-cap ($2-10 billion), or small-cap (under $2 billion).
Usage Context
Essential for stock valuation, portfolio construction, investment analysis, comparing company sizes, understanding market indices, and making investment decisions based on company scale and risk profiles.
