## Execution Alpha Decay

Execution alpha decay refers to the erosion of the potential profit or advantage of a trading strategy as it is executed over time. When a strategy identifies a mispricing, it must act quickly to capture the profit.

If the execution is slow or causes significant market impact, the favorable price opportunity may vanish or shift, reducing the expected gain. This is a major concern for quantitative funds and high-frequency traders.

Decay is often caused by market participants front-running or reacting to the order flow. Minimizing decay requires highly optimized execution paths and low-latency infrastructure.

It represents the friction between theory and practical realization.
