Multiplicative Langevin process explains q-variance patterns
AFBytes Brief
The study demonstrates that a multiplicative Langevin process reproduces empirical q-variance regularities seen in market volatility data. The framework offers a new lens on volatility dynamics.
Why this matters
Refined volatility models underpin risk management that protects investment portfolios and pension funds.
