Log returns exhibit critical statistical properties, such as non-Gaussian distributions, heavy tails, and volatility clustering, which are foundational for financial modeling, risk management, and asset pricing.
Multiple papers discuss the use of financial log-returns and their specific statistical properties (such as heavy tails, volatility clustering, and non-Gaussian distributions) in financial modeling, risk management, and option pricing. There are no papers contradicting the utility of log returns in financial modeling.
