CHAT targets companies globally that are positioned to benefit from the growth of generative AI and related technologies. Generative AI is a part of the broader AI industry that uses a type of deep learning called generative adversarial networks to produce original content in response to user prompts. Eligible companies must derive at least 50% of their revenue from AI and tech-related industries such as software, semiconductors, cloud and network infrastructures, interactive media, and diversified consumer services. The sub-adviser utilizes a proprietary methodology to score each companys thematic relevancy. It consists of a transcript score determined using a keyword analysis on company filings to identify references to AI-related terms and a sector score based on the materiality of generative AI to the firms expected financial performance. The narrow portfolio holds 25 to 50 stocks weighted by the aggregate exposure score, subject to market-cap and liquidity constraints.
