SIXG focuses on US-listed equities tied to the development and deployment of connective technologies, such as 5G or 6G networks. The portfolio consists of 50 securities deriving at least 50% of their revenues from activities, products, or services, such as core cellular network equipment, REITs and MNOs, service assurance and network optimization, and enhanced mobile broadband and related infrastructure. The fund uses a modified market cap-weighted approach with a max weight of 5% per security. The index only selects the largest three REITs and MNOs with a cap of 1.5%. Rebalancing and reconstitution are done semi-annually. SIXG was the first ETF to offer broad exposure to 5G-related opportunities, trading as Defiance Next Gen Connectivity ETF with the ticker FIVG, until it was changed on July 22, 2024. In addition, on Sep. 23, the index changed its name from BlueStar 5G Communications Index to better represent its updated exposure.
