DAT provides exposure to an index of developed and emerging market companies that have businesses related to the big data market. The fund primarily selects securities classified in one of the nine RBICS sub-industries that generate at least 75% of their revenue from managing, analyzing, storing, or extracting large sets of data. In situations where fewer than 25 companies meet the criteria, the revenue threshold will be lowered to 50% with the next highest revenue percentage companies are selected to complete the list. Constituents must also meet investability and liquidity requirements including a minimum market-cap of $500 million and three-month average daily trading value of at least $1 million. The fund employs a market-cap-weighting scheme with individual security capping at 4.5%. The Index is reconstituted and rebalanced semiannually in June and December.
