Health Care Stocks

The health care sector covers pharmaceutical and biotech companies, medical-device makers, health insurers, hospital operators, and life-science tools and services. Some of these businesses are steady and defensive (people need care in any economy); others, especially clinical-stage biotech, can be highly volatile and binary, rising or falling sharply on a single trial result or regulatory decision. Catalysts include drug-approval decisions, clinical-trial data, earnings, drug-pricing policy, and merger activity. Because the sector ranges from large, profitable, dividend-paying names to tiny pre-revenue biotechs, the specific company and its stage matter as much as the sector label.
