## Fat Tails in Asset Returns

Fat tails in asset returns refer to the observation that extreme price movements occur more frequently than what is predicted by a normal distribution. In financial markets, this phenomenon, also known as leptokurtosis, means that the probability of a market crash or a parabolic rally is significantly higher than standard models suggest.

This is especially true for cryptocurrencies, which are prone to extreme volatility and liquidity-driven price swings. Ignoring fat tails can lead to severe underestimation of risk, particularly for leveraged positions or short-selling strategies.

Professional traders and risk managers use models that incorporate fat tails to better estimate the potential for extreme losses. It is a critical consideration for capital allocation and stress testing in any financial system.

Recognizing fat tails is the difference between surviving a market crash and being wiped out by it.
