## CUSUM Analysis

CUSUM, or Cumulative Sum control chart, is a technique used to monitor a process for small, persistent changes in the mean. It works by calculating the cumulative sum of deviations from a target value, which makes even small shifts in the data process highly visible over time.

In financial risk management, CUSUM is used to detect the early signs of a structural break or a shift in market regime. By plotting the cumulative sum, traders can see when the model is no longer performing as expected, signaling the need for intervention or retraining.

It is more sensitive to small, persistent shifts than standard threshold-based alerts. This makes it an essential tool for maintaining the integrity of trading models in volatile environments.

It acts as an early warning system for model failure.
