## Fat-Tail Risk Assessment

Fat-tail risk assessment involves evaluating the likelihood of extreme market events that fall outside of normal statistical expectations. In finance, these are often referred to as black swan events.

Crypto markets are prone to these due to their novelty and lack of mature market structure. Assessment involves stress testing portfolios against historical crash scenarios.

It requires looking beyond standard deviation to understand the potential for catastrophic loss. By quantifying this risk, traders can adjust their exposure to avoid total ruin.

It is the ultimate test of a robust trading strategy.
