Simple Definition

Companies worth $2 billion to $10 billion. Balance of growth and stability.

Why It Matters

Mid caps are the Goldilocks zone - not too big, not too small. They've survived the startup phase (lower bankruptcy risk than small caps) but still have growth runway (unlike giant mature companies). Many successful companies pass through mid-cap territory on their way to becoming household names. They're often overlooked by investors chasing either the biggest names or small-cap lottery tickets.

Key Points

  • S&P MidCap 400 (tracked by MDY) is the main mid-cap index
  • Mid caps have historically delivered strong risk-adjusted returns - less volatile than small caps, more growth than large caps
  • Examples: companies that are established but not yet household names in their industries
