Kurtosis in Crypto Returns
Kurtosis measures the peakedness or flatness of a distribution, specifically focusing on the extremity of the tails. High kurtosis in cryptocurrency returns indicates that the asset class is prone to frequent, large price fluctuations compared to a normal distribution.
This is a primary driver of the distributional bias seen in crypto-derivatives, as it signifies that the central tendency is surrounded by extreme outliers. Quantitative models that ignore high kurtosis will consistently underestimate the risk of margin calls and insolvency for leveraged positions.
By quantifying this excess, analysts can better stress-test portfolios against sudden, violent market reversals. It serves as a warning sign for risk managers to maintain higher liquidity buffers.
