Insider Trading & Regulation
Algorithmic surveillance methodology designed to identify coordinated or individual patterns of artificial price inflation followed by rapid liquidation, typically involving material nonpublic information or market manipulation.
Pump-and-dump detection combines temporal clustering analysis, volume-price correlation assessment, and insider transaction timing to flag suspicious sequences. Platforms monitor for rapid accumulation phases (pump) by related parties or beneficial owners, followed by concentrated sell-offs (dump) at elevated price levels within compressed timeframes. Effective detection integrates Form 4 filing timestamps, trading plan adoption notices via Rule 10b5-2, and microstructure signals such as order imbalance ratios and bid-ask spread compression preceding the liquidation event.
Regulatory frameworks including MAR Article 17 suspicious transaction reporting and SEC Rule 10b-5 enforcement require quantitative identification of scheme attributes, conviction scoring, and escalation thresholds. Detection systems employ sector-neutral factor scoring, signal persistence metrics, and regime detection probability to distinguish genuine market stress from coordinated manipulation. False positives are reduced through cross-sectional factor exposure normalization and comparative peer analysis within sector cohorts.
