A Multidimensional View of Risk: Integrating Time-Series and Factor Risk Models to Enhance Decision-Making

Research Paper
August 27, 2025

Risk managers can apply risk-factor models to enhance investment decision-making and elevate the role of risk management within the front office. Traditional time-series models use metrics like value at risk to quantify how much risk a portfolio bears. Factor models address the strategic dimensions: where risk comes from, why it matters and what actions we might take to address these risks. 

Factor model’s structure reduces variability in cross-sectional correlation estimates 

Correlation estimates between MSCI USA Investable Market Index stocks and a hypothetical 10-year zero-coupon Treasury bond, based on a factor and time-series model with comparable half-life. Based on the MAC.L model for the factor model, and an exponentially weighted moving average, six-day returns and a 0.9956 decay factor for the time-series model. As of July 1, 2024.
