Fundamentals
Mid-cap
A mid-cap stock is a company with a market capitalization (total value of all its shares) between roughly $2 billion and $10 billion. Market cap is calculated by multiplying the stock price by the number of shares outstanding. You'll encounter mid-caps when screening stocks or reading investment research—they're the "Goldilocks" zone between small, scrappy startups and massive blue-chip corporations. Mid-caps often offer a balance: more stability than smaller companies, but more growth potential than giants. For example, a regional retailer or mid-sized tech firm might be classified as mid-cap. They're popular with investors seeking growth without extreme risk, though they're still riskier than large-cap stocks.
