In this extended deep dive, guest host Raymond Pang, Senior Researcher at CFA Institute, speaks with Greg Fisher, CFA, about how complexity science can offer a richer lens for understanding uncertainty, market behavior, and the limitations of traditional financial models. Building on themes explored in our recent episode with Richard Bookstaber and Genevieve Hayman — including feedback loops, emergent dynamics, and the need for more adaptive approaches to risk — Fisher expands the discussion to the historical roots of the mechanistic mindset and why a systems-based perspective may benefit investment practitioners. The conversation explores how narratives, structural change, and evolving patterns shape asset prices, and how asset managers can incorporate complexity-informed insights into their research and decision-making.
