## Model Parameter Drift

Model parameter drift is the gradual change in the optimal settings of a model over time due to the evolving nature of the market environment. Unlike sudden regime shifts, drift is a slow, often imperceptible erosion of a model's predictive power as the relationships between variables slowly change.

For instance, the correlation between Bitcoin and traditional equity indices may slowly increase or decrease over months, causing a model calibrated on older data to become progressively less accurate. If left unaddressed, this drift leads to a quiet degradation of performance, often resulting in "death by a thousand cuts" as the strategy slowly loses its edge.

Detecting drift requires longitudinal analysis of model performance and constant vigilance. Successful firms treat their models as living systems that require regular maintenance and re-tuning, ensuring that they do not drift into irrelevance as the market landscape shifts beneath them.
