Signum Investments is a San Francisco-based Core U.S. Equity long/short investment manager launched in 2015 that applies quantitative and machine learning techniques to traditional fundamental active management.

Signum executes on its strategy through integrating three models: a Valuation Model for superior stock composition, a Regime Model that serves as an allocation feature to maintain alignment with the dominant style/factor regime, and a Turbulence Model, which is a risk control feature that monitors for early warning signals of changes to market stability.
