Petter Kolm, PhD, and Gordon Ritter, PhD, join Lotta Moberg, PhD, CFA, to continue their discussion on quantitative investing, focusing on model design, implementation, and real‑world application. The conversation explores how quantitative strategies are refined in practice, the challenges of working with financial data, and the balance between theoretical rigor and practical constraints. Kolm and Ritter also discuss evolving market conditions, sources of edge, and how practitioners can think critically about models, performance, and risk. The discussion highlights the importance of adaptability and disciplined decision‑making when applying quantitative approaches in dynamic markets.

Petter Kolm, PhD and Gordon Ritter, PhD, join Lotta Moberg, PhD, for a conversation on quantitative models, risk, and financial decision‑making. The discussion examines how models are constructed and evaluated, the assumptions that underpin them, and the trade‑offs involved when applying theory to real‑world financial problems. Kolm and Ritter share perspectives on model risk, uncertainty, and the role of judgment alongside data, offering insights relevant to both researchers and practitioners working at the intersection of finance and analytics.

Philip Clements, CFA, Alfonso Ricciardelli, CFA, Matthieu LeBret and Simon Beckman join Will Goodhart (CFA Institute Research Foundation Board of Trustees), to discuss their recent brief on infrastructure debt and its growing role in institutional portfolios. The conversation explores how infrastructure debt has evolved from a niche allocation into a core component of alternative credit, shaped by the energy transition, government funding needs, and limits on bank balance sheets. The guests examine risk characteristics across the asset class, including construction risk, technology change, political uncertainty, and interest‑rate regimes, as well as how infrastructure debt fits alongside equity, private credit, and real assets. The discussion also covers renewable energy, data centers, and why infrastructure is increasingly central to long‑term investment strategy.
