About the ETF

XBI was created on 2006-01-31 by SPDR. The fund's investment portfolio concentrates primarily on health care equity. The ETF currently has 6622.83m in AUM and 141 holdings. XBI tracks an equal-weighted index of US biotechnology stocks.

XBI is one of a handful of biotech ETFs available, offering exposure to a corner of the market that can perform well during periods of consolidation and is capable of big jumps in the event of major drug approvals. XBI focuses on a narrow sector of the health care sector, and as such is probably too precise for most investors seeking to construct a long-term portfolio. However, this ETF can be useful for those seeking to fine tune exposure or for those bullish on the sector over the long run. XBI focuses exclusively on American stocks, and primarily consists of mid cap and small cap securities.
