State Street SPDR S&P Health Care Services ETF(AMEX:XHS)

XHS provides alternate exposure to the US health care providers & services segment by equally weighting its holdings. The fund draws its selection universe from a total market composite index. The resulting broadly defined portfolio includes some related but out-of-segment industries like medical equipment, pharmaceuticals, and drug retailers. Given its equal-weighting, XHS tilts vastly smaller and underweights the large managed health care firms that dominate the space. Note: Instead of replicating the index, the fund uses a sampling strategy. The index is rebalanced quarterly.
