UnitedHealthUNH

UnitedHealth Group (UNH) is the largest health-insurance and healthcare-services company in the US by revenue. It runs two big segments: UnitedHealthcare (health insurance) and Optum (pharmacy benefits, healthcare services and data analytics). Listed on NYSE and historically the heaviest weight in the price-weighted Dow Jones Industrial Average. Cyclical-defensive — sensitive to medical-cost inflation, Medicare Advantage policy changes and broader US-healthcare reform politics. Like any single stock, the price can fall sharply on disappointing earnings or regulatory news. Diversify and invest carefully.
