The Properties of Realized Correlation : Evidence from the French, German and Greek Equity Markets
Vortelinos, Dimitrios I. - 2015
In this paper I examine the properties of four realized correlation estimators and model their jumps. The correlations …-of-the-art realized correlation estimators which I then use to testing for normality, long-memory, asymmetries and jumps and also to … modeling for jumps. Jumps are detected when the realized correlation is higher than 0.99 and lower than 0.01 in absolute values …

Modeling and Forecasting Realized Range Volatility
Caporin, Massimiliano - 2011
In this paper, we estimate, model and forecast Realized Range Volatility, a new realized measure and estimator of the quadratic variation of financial prices. This estimator was early introduced in the literature and it is based on the high-low range observed at high frequency during the day. We...

Forecasting Realized Volatility : Does Anything Beat Linear Models?
Branco, Rafael; Rubesam, Alexandre; Zevallos, Mauricio - 2022
We evaluate the performance of several linear and nonlinear machine learning models in forecasting the realized volatility (RV) of ten global stock market indices in the period from January 2000 to December 2021. We train models using a dataset which includes past values of the RV and additional...
