Distribution Assumption Analysis
Distribution assumption analysis is the process of evaluating whether the statistical properties of asset returns conform to a specific probability distribution model. In financial markets, particularly cryptocurrency and options trading, analysts often assume returns follow a normal distribution, represented by the bell curve.
However, empirical data frequently shows fat tails or leptokurtosis, meaning extreme price swings occur more often than a normal distribution predicts. This analysis is critical for pricing derivatives, as incorrect assumptions lead to mispriced options and inaccurate risk assessments.
By testing for skewness and kurtosis, traders can better understand the true probability of tail events. Failing to account for non-normal distributions often results in underestimating the risk of catastrophic loss during market volatility.
Quantitative finance relies on these assumptions to calibrate Greeks like Gamma and Vega. Accurate distribution analysis ensures that risk management frameworks are robust enough to handle the reality of market behavior.
