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. Prior to October 3, 2024, the fund was known as Amplify Mobile Payments ETF.
