In this episode of Flirting with Models, Corey Hoffstein interviews Jay Rajamony, Director of Alternatives at ManNumeric, about the evolution of quant equity investing. Jay shares his experiences from the past two decades, discussing the shift from simple factor models to complex alternative data and machine learning approaches. They explore the impact of events like the 2007 quant quake and the 2008 financial crisis, the relevance of traditional factors in the modern environment, and the interplay between macro regimes and factor behavior. The conversation also covers the challenges and opportunities of using alternative data, the importance of organizational structure in quant firms, modern risk management techniques, and the role of discretionary intervention in systematic processes.
