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 549 micro cap Healthcare stocks — companies in the Healthcare sector with a market cap under $250M — worth a combined $33.2B.

The largest by market cap are Lineage Cell Therapeutics (LCTX) at $249M, BioAge Labs (BIOA) at $249M and Bicycle Therapeutics (BCYC) at $246M.

Among institutional investors, Glass House Brands (GLAS) drew the most net new fund positions in Q2 2026: 50 funds opened new positions, taking total fund holders up 50 (1,667%) quarter-over-quarter.
