What Is Market Capitalization?
Market capitalization (market cap) is the total dollar value of a company's outstanding shares of stock. It is calculated by multiplying the current share price by the total number of outstanding shares. Market cap is one of the most widely used metrics to gauge a company's size and is a key factor in stock classification, index composition, and investment analysis.
