Fund Details
Investment Thesis
The index fund answer to the AI trade: Morningstar's committee-free selection spreads the bet across the silicon layer (AMD, Broadcom, TSMC), the build-out layer (CoreWeave, Super Micro, Oracle) and the appliers, capped so no single name decides the year. +33% with contributions from every layer, at an index fee half what active AI funds charge. iShares' scale made it a $3.9B fund within its first renamed year.
Who It's For
AI investors who want the theme indexed, capped and cheap — broad exposure across the stack without a manager's concentration calls.
