Can A.I. Improve Investment Results? With Rob Arnott, Founder & Chair of Research Affiliates.

Rob Arnott, Founder & Chair of Research Affiliates, discusses where AI works well & can assist across the money management ecosystem, the risk of ‘AI hallucination’ & over-reliance, quant vs human judgement, and the future of work. 

Amidst the volumes written about AI’s impact on the business and investing worlds, we wanted to ask some specific questions about adoption, learning, implementation and limitations within the investing universe. 

We asked these questions of Rob Arnott, founder of Research Affiliates and a previous guest, whose firm is steeped in data, systematic disciplines and empirical evidence. In a compelling and engaging conversation, Rob discusses why common sense can beat data, how AI can hallucinate, its creative limitations, but its unequivocal potency in improving multiple areas of the investing business. 

Finally, when asked for his convictions across markets, he discusses the exceptional value in US small vs large cap equity!
