Mid-Cap

Corporations with a market valuation (capitalization) between $2 and $10 billion are referred to as mid-cap (or mid-capitalization) companies. A mid-cap corporation, as its name suggests, is in between large-cap (or big-cap) and small-cap firms. Large-cap, mid-cap, and small-cap classifications are estimations of a company's current worth; as such, they may fluctuate over time.
