The asymmetry observed in asset return distributions, where one tail is heavier than the other, is a defining characteristic deviating from the symmetric normal curve. Negative skew, common in equity-like assets, implies a higher probability of large negative returns than large positive ones. This asymmetry directly impacts the relative pricing of puts versus calls.
Kurtosis
This measure quantifies the “tailedness” of the distribution, indicating the frequency of extreme deviations relative to a Gaussian benchmark. High positive kurtosis, or leptokurtosis, signifies a greater likelihood of observing price movements that fall into the fat tails. Such characteristics necessitate the use of models that explicitly account for this excess probability mass.
Assumption
Reliance on the normal distribution for option pricing, as in the Black-Scholes framework, becomes analytically flawed when applied to crypto derivatives exhibiting these properties. Practitioners must employ stochastic volatility or jump-diffusion models to better capture the observed empirical behavior. Violating this core assumption leads to systematic mispricing of risk.
