Log-Normal Distribution

Application

The Log-Normal Distribution frequently models asset prices in cryptocurrency markets, particularly when considering continuous proportional changes rather than additive ones, reflecting the non-negative nature of price data. Its utility extends to options pricing, where it’s employed in certain models to represent the distribution of underlying asset prices at expiration, offering a more realistic depiction than a normal distribution given the potential for significant positive skewness. Within financial derivatives, this distribution is crucial for risk management, specifically in calculating Value at Risk (VaR) and Expected Shortfall, providing a framework for quantifying potential losses. Consequently, understanding its properties is essential for traders constructing portfolios and managing exposure to volatility.
