Micro Cap Healthcare Stocks at a Glance

Healthcare companies develop drugs, build medical devices, run hospitals and insurers, and supply the systems behind patient care. Demand is largely non-discretionary, but returns hinge on drug-pipeline outcomes, patent lives, and reimbursement policy — a mix of defensive services and high-risk, high-reward research bets.

There are 547 micro cap Healthcare stocks — companies in the Healthcare sector with a market cap under $250M — worth a combined $32.8B.

The largest by market cap are Larimar Therapeutics (LRMR) at $249M, Treace Medical Concepts (TMCI) at $248M and BioAge Labs (BIOA) at $247M.
