The HealthShares Composite ETF (Ticker: HHQ) seeks to replicate as closely as possible, before expenses, the total return performance of the HealthShares Composite Index. The Index is comprised of small and mid-capitalization common stocks and ADRs engaged in healthcare, life sciences and/or biotechnology companies. Companies are screened to eliminate those with market capitalizations above $20 billion or below $100 million. The Index consists of the 80 largest companies by market capitalization taken from the top five companies in market capitalization from each of the Composite Eligible Indexes. The weighting of stocks in the Index is not explained in the prospectus or marketing literature except to say that the fund weightings follow the Index. As best that can be determined from external sources the fund is equal weighted and rebalanced each quarter.
