NEW YORK–(Business Wire)–Axioma today announced that the company was awarded a patent for Axiomas Dynamic Volatility Adjustment algorithm (DVA). This innovation improves the responsiveness and quality of Axiomas equity risk models, while maintaining stability during critical shifts in market volatility. DVA supports the construction of factor risk models that better predict the future volatility of portfolio returns.
DVA improves risk forecasts without increasing noise or turnover, said Simon Bell, Director, Research, who developed the algorithm with Frank Siu, Director, Index Research.
Risk models base forecasts on historical data and they are typically slow to react during spikes or drops in market volatility. DVA provides an automated process that calibrates historical factor return weights in order to provide the most realistic model for the current volatility regime.
Improved factor-factor covariance estimation is achieved even when the covariances change rapidly over time, said Bell. DVA helps factor risk models achieve better accuracy, responsiveness, and stability.
Axioma is the only technology provider for portfolio managers that provides an entire suite of risk modeling capabilities, including off-the-shelf, fundamental, statistical, and macro modeling products delivered daily, as well as the ability to create custom risk models.
Axiomas DVA algorithm is protected by U.S. patent #8,700,516, “Method and Apparatus for Improving Factor Risk Model Responsiveness.”
