We introduce the notion of realized copula. Based on assumptions of the marginal distributions of daily stock returns … and a copula family, realized copula is defined as the copula structure materialized in realized covariance estimated from … within-day high-frequency data. Copula parameters are estimated in a method-of-moments type of fashion through Hoeffding …

This paper provides a strategy for portfolio risk management by inferring extreme movements in financial markets. The core of the provided strategy is a statistical model for the joint tail distribution that attempts to capture accurately the data generating process through an extremal modelling...
