SimCorp has launched a new global equity factor risk model designed to help hedge funds and active asset managers manage short-horizon trading strategies following a year marked by sharp market swings and crowded trades.
The Axioma Worldwide Equity Factor Risk Model: Trading Horizon is built to support investment strategies with holding periods measured in days or weeks, including systematic, quantitative and algorithmic approaches. The model forecasts equity risk over a 20-day horizon and updates factor exposures and returns daily, enabling portfolio managers to respond more quickly to abrupt changes in market conditions.
According to SimCorp, the new model is more responsive to market shifts than traditional short- and medium-horizon risk models, capturing changes in volatility with greater speed and magnitude — a feature the firm says is increasingly critical in fast-moving markets.
The Trading Horizon Model incorporates specialised style factors, including Opinion Divergence and Short Interest, alongside fundamental and market-based inputs tailored specifically for short-term strategies. These features are designed to provide granular insight into liquidity conditions, downside risk and non-linear residual effects, which have become prominent drivers of short-term volatility.
SimCorp said the model is particularly relevant in the current environment, where AI-related equity flows and geopolitical tensions have intensified short-term market dynamics. Last year’s surge in capital into artificial intelligence-linked stocks amplified momentum and crowding risks, while tariff disputes between major economies triggered abrupt currency movements and sector rotations.
Following tariff announcements on 2 April, SimCorp noted that the Trading Horizon Model registered a sharp increase in its risk forecast — nearly doubling from one day to the next — a move that significantly exceeded responses from other Axioma model variants.
The firm said portfolio managers using the model can quantify exposure to exchange rate sensitivity to hedge against FX-driven shocks, monitor short-term momentum and crowding risks in thematic trades such as AI, and assess liquidity and downside risk on a daily basis.
The model is available immediately as a standalone product or as part of the Axioma Risk suite within SimCorp One.
