State Street SPDR S&P Biotech ETF (XBI) Price and Market Data

SPDR S&P Biotech ETF is an exchange-traded fund that gives investors diversified exposure to U.S. biotechnology companies. It is designed to track or represent a basket of publicly traded securities rather than a single company, making it useful for portfolio allocation, regional exposure, and thematic positioning. Its performance depends on the underlying holdings, sector and country weights, currency movements where relevant, fund expenses, and broader equity-market conditions.
