Forecasting the volatility of Nikkei 225 futures

Asai, Manabu; McAleer, Michael - 2017 - Revised: January 2017

For forecasting volatility of futures returns, the paper proposes an indirect method based on the relationship between … futures and the underlying asset for the returns and time-varying volatility. For volatility forecasting, the paper considers … that the new method based on stochastic volatility models with the asymmetry and long memory outperforms the forecasting …

Modeling and Forecasting S&P 500 Volatility: Long Memory, Structural Breaks and Nonlinearity

Martens, Martin; van Dijk, Dick; de Pooter, Michiel - 2004

The sum of squared intraday returns provides an unbiased and almost error-free measure of ex-post volatility. In this paper we develop a nonlinear Autoregressive Fractionally Integrated Moving Average (ARFIMA) model for realized volatility, which accommodates level shifts, day-of-the-week...

Simple (but effective) tests of long memory versus structural breaks

Shimotsu, Katsumi - 2006

This paper proposes two simple tests that are based on certain time domain properties of I(d) processes. First, if a time series follows an I(d) process, then each subsample of the time series also follows an I(d) process with the same value of d. Second, if a time series follows an I(d)...

Comparing predictive accuracy under long memory: With an application to volatility forecasting

Kruse, Robinson; Leschinski, Christian; Will, Michael - 2016

This paper extends the popular Diebold-Mariano test to situations when the forecast error loss differential exhibits long memory. It is shown that this situation can arise frequently, since long memory can be transmitted from forecasts and the forecast objective to forecast error loss...

Finite sample accuracy of integrated volatility estimators

Nielsen, Morten Ørregaard; Houmann Frederiksen, Per - 2005

We consider the properties of three estimation methods for integrated volatility, i.e. realized volatility, the Fourier estimator, and the wavelet estimator, when a typical sample of high-frequency data is observed. We employ several different generating mechanisms for the instantaneous...

Long memory, realized volatility and HAR models

Baillie, Richard; Calonaci, Fabio; Cho, Dooyeon; Rho, … - 2019

The presence of long memory in Realized Volatility (RV) is a widespread stylized fact. The origins of long memory in RV have been attributed to jumps, structural breaks, non-linearities, or pure long memory. An important development has been the Heterogeneous Autoregressive (HAR) model and its...
