Healthcare & Biotech Sector -- Stock Tracker

Sectors

Healthcare & Biotech Sector

Healthcare is a defensive sector -- people need medicine regardless of the economy. Biotech is a high-risk sub-sector where FDA trial results can move stocks 50%+ in a day. The GLP-1 obesity drug wave (Ozempic, Zepbound) is the sector's biggest current theme.

Healthcare sub-sectors

Large pharma (JNJ, PFE, MRK): diversified drug portfolios, stable dividends.
  Biotech (MRNA, REGN, AMGN): fewer products, massive upside/downside on trials.
  Health insurers (UNH, CVS): benefit from aging population and ACA.
  Medical devices (MDT, SYK, ISRG): recurring procedure revenue.
  Specialty pharma (LLY, ABBV): focused on high-margin blockbuster drugs.

FDA catalyst events

The FDA approval calendar is more important than earnings for biotech stocks.
  PDUFA date: FDA deadline to approve/reject a drug application.
  Phase 3 trial results: the largest catalyst for clinical-stage biotechs.
  Stock reaction: approval = +30-100%; rejection = -50-80%.
Never hold through an FDA decision without understanding the risk.
