The index is a rules-based index that consists of globally-listed stocks and depositary receipts of companies that, at the time of being added to the index, derive at least 50% of their revenues or operating activity from solutions for the creation, management, analysis, storage, or transmission of large sets of data as determined by the index provider. Under normal circumstances, the fund invests at least 80% of its net assets (plus borrowings for investment purposes) in pure-play Big Data companies. It is non-diversified.
