Mid-cap (mid-capitalization) means stocks of publicly traded companies with a market capitalization between $2 billion and $10 billion as per global standards. A mid-cap stock offers a middle ground between the growth potential of a small-cap and the reduced volatility of a large-cap. A mid-cap stock tends to offer greater growth potential than a large-cap. It is prone to be more volatile than a large-cap stock but less volatile than a small-cap stock and less vulnerable in economic downturns, compared to a small-cap stock.
