The Breach Became a Time-Series Event
EventTime fused market history with breach metadata to estimate short-term abnormal losses after disclosures.
Summary
EventTime fused market history with breach metadata to estimate short-term abnormal losses after disclosures.
EventTime combines long-horizon market context, immediate pre-event behavior and event metadata, with contrastive learning designed for sparse, heterogeneous shocks. The accompanying SECURE dataset aligns cybersecurity incidents with stock-market series and structured plus model-derived features. Across the authors’ tests it outperformed time-series and event-aware baselines, but it estimates associations in historical data rather than guaranteeing a tradable forecast or causal loss figure.
