Tail Index

Calculation

The Tail Index, within cryptocurrency and derivatives markets, quantifies the likelihood of extreme negative price movements, extending beyond those predicted by normal distribution models. It’s derived from options pricing data, specifically focusing on out-of-the-money put options, to estimate the probability of substantial declines in underlying asset values. This metric provides a risk assessment tool, indicating potential market stress and informing strategies for portfolio hedging or tail risk mitigation. Consequently, a higher Tail Index suggests increased investor concern regarding downside volatility and potential market crashes.
