iShares U.S. Tech Breakthrough Multisector ETF(AMEX:TECB)

TECB tracks a rules-based equity index of US listed companies engaged in the research and development of products and services in one of five thematic segments: (i) robotics and artificial intelligence, (ii) cyber security, (iii) cloud and data tech, (iv) financial technology, and (v) genomics and immunology. Components are grouped utilizing RBICS classifications. To be included in the index, securities must meet market cap and ADTV requirements and most of their revenues must be derived from their specific themes, with an additional screen to the Genomics and Immunology theme. The index provider uses automated semantic search algorithms to identify supply chain relationships in the Genomics and Immuno Biopharmaceutical segment. A composite relationship score for each stock in the segment is calculated with the top 50 being selected. Weighting of the portfolio is a mix of segment weight, set at a minimum of 10%, and individual security, set at a maximum of 4%. The Index will be reconstituted annually and rebalanced semiannually.
