On October 31st, CARTE Industry Speaker Seminar Series welcomes Quentin Bartram from Morningstar.

Title: Anomaly Detection – What to Do without Enough Data

Abstract: Detecting anomalies in managed investment products is crucial for making timely investment decisions, yet limited data often hinders traditional detection methods. In this talk, “Anomaly Detection—What to Do Without Enough Data,” we explore innovative strategies to accurately identify significant changes in fund performance, operations, and portfolio composition despite data constraints.

We discuss various methodologies, including supervised and unsupervised machine learning, ensemble models, and a statistically driven rules-based approach. By evaluating the effectiveness of each method in low-data scenarios, we highlight how selective application or combination of techniques enhances detection accuracy. The project culminates in a robust model and process of identifying anomalies that promptly alerts analysts to noteworthy fund changes, enabling swift and appropriate adjustments to fund ratings. Future work involves integrating a human-in-the-loop (HITL) machine learning process to leverage analyst feedback for continual improvement in anomaly detection.
