Skew and Kurtosis Shifts

Skew and kurtosis are statistical measures that describe the shape of a probability distribution, which are critical in options pricing. Skew measures the asymmetry of the distribution, while kurtosis measures the thickness of the tails, indicating the probability of extreme events.

In derivatives, shifts in these parameters represent changing market expectations for large price moves. A rise in kurtosis suggests that the market is pricing in a higher likelihood of black swan events.

Traders monitor these shifts to adjust their risk management strategies and hedge against tail risk. Understanding these dynamics is essential for navigating volatile financial environments.
