Sažetak
The estimation and prediction of financial asset volatility are
important in terms of theoretical and practical applications.
Considering that low-frequency and high-frequency information
plays an important role in volatility prediction, this article proposes
a mixed-frequency model based on the momentum of predictability
(MF-MoP). To illustrate the advantages of the proposed
model, comparative research is conducted on the prediction
accuracy of volatility among the GARCH model, the Realized
GARCH model and the MF-MoP model, by the loss function and
MCS test. The empirical results show that the MF-MoP model has
higher prediction accuracy than the other two models; especially
based on skewed-t distribution, the MF-MoP significantly outperforms
the competing models. Moreover, the MF-MoP model can
improve the forecasting of volatility, regardless of different lookback
periods (including 1, 3, 6 and 9 days), different data (including
the CSI 300 index, the N225 index and the KS11 index), and
realized measures (including RV, RRV and MedRV), indicating that
the model is robust.
