Healthcare Sector Overview
Healthcare is a defensive sector that tends to be less sensitive to economic cycles—people need healthcare regardless of the economy. It represents about 12% of the S&P 500.
Why Invest in Healthcare?
- Defensive: Less cyclical than most sectors
- Demographics: Aging population drives demand
- Innovation: Biotech and medical devices offer growth
