Mid Cap
Companies with a market capitalization roughly between $2 billion and $10 billion — the "sweet spot" for growth with established business models.
Mid-cap stocks occupy the middle tier between large and small caps. They are often businesses that have proved their model and are still in a significant growth phase — not yet the household names of large cap but far beyond startup risk.
Mid caps historically deliver returns between large and small caps over long periods, with less volatility than small caps. They are less covered by analysts than large caps, creating more opportunity for research-driven edge.
The S&P MidCap 400 is the benchmark index for this segment. Many mid caps are acquisition targets for large caps looking to buy established growth.
