Volatility Persistence Patterns

Definition

Volatility persistence patterns represent the observed tendency of price fluctuations in cryptocurrency markets to cluster in time, where periods of high realized variance are frequently followed by further instability. This phenomenon, often quantified through GARCH-type processes, highlights that market shocks do not dissipate instantaneously but instead decay over predictable temporal horizons. Quantitative analysts monitor these sequences to assess the decay rate of risk premiums, which remains a cornerstone of sophisticated derivatives pricing and delta-hedging operations.
