About Market Capitalization. Market Capitalization (Market Cap) is a measurement of business value based on share price and number of shares outstanding. It generally represents the market's view of a company's stock value and is a determining factor in stock valuation. For example, if a company has 1.5 million shares outstanding at a share price of $25, its market cap is $37.5 million (1.5 million x $25). Companies can be categorized based upon the size of their market capitalization. There are five basic groups: mega-cap (market cap over $200B), large-cap ($10Bâ$200B), mid-cap ($2Bâ$10B), small-cap ($300Mâ$2B), and micro-cap ($50M-$300M).
