Stocks with a market capitalization between $2 billion and $10 billion are generally classified as mid-cap stocks.
“Market capitalization,” or market cap, is calculated by multiplying a company’s share price by its total shares outstanding. It provides a rough measure of company size, alongside categories such as mega-cap, large-cap, small-cap, and micro-cap.
The $2 billion–$10 billion range is a typical U.S. convention, not a universal legal standard. Investment firms and index providers may use different thresholds, and the boundaries change over time as markets, inflation, and company valuations change. For example, a stock near $10 billion could be classified differently by two providers.
Mid-cap companies sit between smaller, potentially faster-growing businesses and established large-cap corporations. Investors often view them as offering a balance of growth potential and financial maturity, though they can still be more volatile than large-cap stocks.
