ARTY is a global fund following the top 50 companies from both developed and emerging markets that are involved artificial intelligence (AI). The funds underlying index scores companies based on level of exposure to four subthemes: generative AI, AI data and infrastructure, AI software, and AI services. The scoring process takes into consideration the companys role in the AI value chain, expected net profit increase from the exposure to at least one of the AI subthemes, and the portion of revenue expected to be derived from each AI subtheme over the next five years. The index provider ranks companies into three tiers, emphasizing those with the greatest tie to the AI subthemes and current market capitalization. Preference is given to smaller market capitalization over larger. The index is reconstituted annually and rebalanced quarterly. Prior to August 12, 2024, the fund ticker was IRBO and tracked the NYSE FactSet Global Robotics and Artificial Intelligence Index.
