We propose a dynamic factor state-space model for the prediction of high-dimensional realized covariance matrices of … linear shrinkage. We find that the proposed model performs very well in an empirical application to realized covariance … asset returns. Using a block LDL decomposition of the joint covariance matrix of assets and factors, we express the realized …
