Kurtosis

Definition

In the domain of quantitative finance and derivatives trading, this metric serves as a statistical measure quantifying the heaviness of the tails of a probability distribution relative to a normal distribution. Traders utilize this indicator to assess the propensity of an asset, such as a volatile cryptocurrency, to produce outlier returns that deviate significantly from historical mean behavior. High values signal a peaked distribution with frequent extreme observations, which directly informs the risk profile of portfolio tail exposure.
