Abstract
We examine how skewness interacts with kurtosis within the cryptocurrency market. We show that during the COVID-19 pandemic there are more clusters of observations around the two flanks, highlighting the presence of a volatile behavior. Moreover, we document the evolvement of the interrelationship as the pandemic progresses, identifying the domination of the extremes. Our findings advance the thinking that by exploiting the interrelationship between the two higher moments of cryptocurrencies, investors and researchers can have in their arsenal an additional analytic tool.
Complexity vs Empirical Score
- Math Complexity: 3.5/10
- Empirical Rigor: 5.5/10
- Quadrant: Street Traders — practical and empirical, lighter on theory
Why this score: The paper applies established statistical methodologies for higher moments (skewness and kurtosis) to cryptocurrency data across pre- and post-COVID periods. While mathematically straightforward, the empirical evaluation uses a decent panel of the top 50 cryptocurrencies, though the overall novelty is incremental.
