## Alpha Decay Analysis

Alpha decay analysis measures the rate at which a trading strategy's excess returns, or alpha, diminish over time. All trading strategies have a limited lifespan as market participants learn to exploit the same inefficiencies, or as the market evolves to eliminate the edge.

Alpha decay is a natural part of the competitive process in financial markets. Quantitative firms track this decay to determine when to invest in new research and when to abandon a dying strategy.

In cryptocurrency, alpha decay can be extremely rapid due to the high speed of innovation and the relatively low barrier to entry for new market participants. By quantifying this decay, firms can manage their portfolio of strategies, ensuring that they are always focused on the most profitable opportunities.

It is a vital metric for long-term survival in quantitative finance.
