The Fidelity Digital Health Index SM is designed to reflect the performance of a global universe of companies across the market capitalization spectrum providing healthcare records management, connected healthcare devices, surgical robotics, telemedicine, and other technology-enabled healthcare products and services. The Fidelity Digital Health Index SM is constructed using Fidelity's rules-based proprietary index methodology. The index methodology identifies and ranks stocks for inclusion in the index based on company revenues and proprietary natural language processing (NLP) scores. Stocks of companies are first selected based on market share and revenues tied to one or a combination of the following designated business activity categories, subject to thematic quality screens: digital healthcare products & services and connected medical devices. After initial screens are applied, stocks are selected for inclusion in the index based on market share ranked by dollar revenue and a thematic relevancy score derived from a combination of revenue related to designated business activities and NLP scores. NLP is used to analyze text-based documents to identify companies with relevant keywords. Stocks of companies with greater than 50% of their total revenue from one or a combination of designated business activities or at least 5% market share (based on total revenues in designated business activities) will comprise 85% or more of the index. Stocks not meeting these criteria may also be included in the index but are generally capped at lower weights. Each stock is weighted by adjusted market capitalization and capped under the methodology. Effective December 11, 2025, derivative instruments that provide investment exposure to the investments above or exposure to one or more market risk factors associated with such investments are included in the fund's 80% policy, consistent with the fund's investment policies and limitations with respect to investments in derivatives.
