Dynamic correlations and optimal hedge ratios
Bos, Charles S.; Gould, Phillip - 2007
good on the present set of measures as the stochastic volatility models, with or without dynamic correlation. …The focus of this article is using dynamic correlation models for the calculation of minimum variance hedge ratios …. Modelling the correlation explicitly is shown to produce the best hedges when applied to the simulated data. For financial time …

Fractional integration and fat tails for realized covariance kernels and returns
Lucas, André; Opschoor, Anne - 2016 - This version: September 1, 2016
We introduce a new fractionally integrated model for covariance matrix dynamics based on the long-memory behavior of daily realized covariance matrix kernels and daily return observations. We account for fat tails in both types of data by appropriate distributional assumptions. The covariance...
