Market Capitalization
is the total market value of a company's outstanding shares. Calculated as: Stock Price × Total Shares Outstanding.
Market cap tells you how big a company is. Used to classify stocks as small cap, mid cap, or large cap.
Quick answer
Market Cap = Stock Price × Shares Outstanding. Large cap ($10B+) = stable. Mid cap ($2-10B) = balanced. Small cap (under $2B) = higher risk/reward.
Market capitalization equals share price times shares outstanding — the market's total valuation of a company's equity.
What Is Market Cap?
Market cap = Stock Price × Shares Outstanding. Apple at $185 with 15.5B shares = $2.9 trillion market cap.
