  This paper uses new and recently introduced methodologies to study the
similarity in the dynamics and behaviours of cryptocurrencies and equities
surrounding the COVID-19 pandemic. We study two collections; 45
cryptocurrencies and 72 equities, both independently and in conjunction. First,
we examine the evolution of cryptocurrency and equity market dynamics, with a
particular focus on their change during the COVID-19 pandemic. We demonstrate
markedly more similar dynamics during times of crisis. Next, we apply recently
introduced methods to contrast trajectories, erratic behaviours, and extreme
values among the two multivariate time series. Finally, we introduce a new
framework for determining the persistence of market anomalies over time.
Surprisingly, we find that although cryptocurrencies exhibit stronger
collective dynamics and correlation in all market conditions, equities behave
more similarly in their trajectories, extremes, and show greater persistence in
anomalies over time.
