## Black Swan

A Black Swan is a rare, unpredictable, and extreme financial event that falls outside the realm of regular expectations. In the context of cryptocurrency and derivatives, it represents a catastrophic market crash or systemic failure that market models failed to account for because historical data did not suggest such an occurrence was possible.

These events carry severe consequences and are often rationalized only after they have occurred, making them seem inevitable in hindsight. For traders, Black Swans highlight the danger of relying solely on historical volatility data to predict future risk.

They often expose hidden vulnerabilities in leveraged positions or poorly designed smart contracts. Investors cannot predict these events, but they can build portfolios that are robust enough to survive them.

A Black Swan effectively resets the market environment, forcing a reassessment of risk parameters across all protocols.
