## Algorithmic Signal Alpha Decay

Algorithmic signal alpha decay is the process by which a specific trading signal loses its ability to generate excess returns as it becomes known to the broader market. When an algorithm identifies a new way to profit, it may perform well initially, but as other participants implement similar models, the inefficiency is closed.

This decay can be rapid in highly competitive digital asset markets. To combat this, quantitative traders must continuously research and develop new signals.

It is a constant cycle of innovation and obsolescence. The rate of decay is a key metric for evaluating the long-term viability of a trading strategy and the necessity for ongoing research and development.
