Log returns possess specific statistical and economic properties useful for financial modeling.
Is it true that log returns possess specific statistical and economic properties useful for financial modeling?
Yes. 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.
Verdict: SUPPORTED · 8 sources for, 0 against · Last checked
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.
