IPAY passively provides pure-play exposure to the mobile payments industry. The index uses a sector classification scheme developed by the Consumer Technology Association (CTA) to identify companies that derive significant revenue from the following mobile payments categories: card networks, infrastructure & software, processors, and solutions. Eligible companies must meet minimum market capitalization and liquidity requirements. The index expects to hold a narrow portfolio of up to 50 companies, weighted using a theme-adjusted market capitalization scheme. The index is reconstituted semi-annually and rebalanced quarterly. Before January 29, 2024, IPAY traded under the brand name ETFMG and tracked the Prime Mobile Payments Index.
