iShares Exponential Technologies ETF(NASDAQ:XT)

XT invests in firms involved with production and use of groundbreaking technologies or exponential technologies. Morningstar determines the related-themes and may revise it annually, the following themes are: big data and analytics, nanotechnology, medicine, networks, energy and environmental systems, robotics, 3-D printing, bioinformatics and financial services. Eligible stocks must be in the Morningstar Global Equity Index family. The selection and weighting of companies is done with a somewhat-opaque method, using fundamental research to score companies along a three-point scale based on exponential technology involvement while applying liquidity screens. It then ranks the remaining stocks by exposure to the exponential technology themes with bias to small caps, up to five stocks within each theme are considered until the final constituents reach 200. The Underlying Index is equal weighted and is reconstituted and rebalanced annually.
