Normal Distribution Assumption
The normal distribution assumption is a common statistical framework where financial returns are modeled as following a bell-shaped curve. This assumption simplifies the pricing of derivatives, such as the Black-Scholes model, by allowing for the use of standard mathematical tools.
However, real-world financial data often exhibits fat tails, meaning extreme events occur more frequently than the normal distribution predicts. In the context of crypto-assets, which are prone to extreme volatility and flash crashes, this assumption can be dangerous.
Relying solely on it can lead to underestimating the risk of catastrophic loss. Professional traders and risk managers must account for these non-normal features by using alternative models or adjusting their risk parameters.
It is essential to recognize the limitations of this assumption when dealing with highly speculative assets. By understanding where the assumption fails, traders can build more resilient portfolios.
It serves as a baseline for comparison rather than an absolute truth. Correcting for non-normality is a key challenge in modern quantitative finance.
