How do quantitative investors adapt when markets, technology and macro regimes are constantly changing? In this conversation, Alan Dunne sits down with George Patterson, CIO of PGIM Quant Solutions, to explore the evolution of systematic investing from the 1990s to today’s AI driven landscape. They discuss regime detection, inflation risk, portfolio construction, machine learning, private markets, volatility overlays and the growing role of language models in investment research. George also shares insights from decades in quant investing, including lessons from Covid, the importance of model discipline and why communication skills matter as much as technical expertise.
