Mid-Cap Stock

The growth-stability sweet spot between small and large caps

Definition

Mid-cap stocks represent companies with a market capitalization typically between $2 billion and $10 billion. They occupy a sweet spot between the stability of large-caps and the growth potential of small-caps. Mid-caps often grow faster than large-caps but carry less risk than small-caps. The S&P MidCap 400 tracks these companies.

Example
A regional airline with a $5 billion market cap is a mid-cap stock. It has enough scale to weather economic downturns better than a startup airline, but still has significant runway for growth compared to a mega-cap like Delta Air Lines.
