Alternative Data for Realised Volatility Forecasting: Limit Order Book and News Stories

International Journal of Finance &Economics, EarlyView.
ABSTRACT We examine whether two major alternative data sources, limit order book information and firm‐specific news, provide incremental predictive information for daily realised volatility forecasting within the HAR‐family, using a parsimonious framework to ensure practical implementation and comparability. The framework is designed for practical real‐

Volatility Spillover of Brent Oil Price Return on Return of Iran and USA Financial Markets and Related Industries: A MGARCH Approach [PDF]

Pizhūhishnāmah-i Iqtiṣād-i Inirzhī-i Īrān, 2016
The importance of oil price volatility spillover has significantly increased since the globalization and financial markets’ interaction have expanded. Based on this, the oil price impact on financial markets, as an exogenous variable, is also increased ...

Modeling the Nexus Between Climate Risk, Energy Consumption, and Financial Market Performance in Emerging Countries

International Studies of Economics, EarlyView.
Abstract This paper examines the link between climate risk, energy consumption, and financial market performance in a sample of emerging countries over the period 2000–2024. The objective is to model the dynamic interactions between these three dimensions, in order to understand the extent to which energy dependence and exposure to climate risks ...

Modeling of the Bitcoin Volatility through Key Financial Environment Variables: An Application of Conditional Correlation MGARCH Models

Mathematics, 2021
Since the launch of Bitcoin, there has been a lot of controversy surrounding what asset class it is. Several authors recognize the potential of cryptocurrencies but also certain deviations with respect to the functions of a conventional currency. Instead,

Multivariate Variance Targeting in the BEKK-GARCH Model [PDF]

SSRN Electronic Journal, 2012
This paper considers asymptotic inference in the multivariate BEKK model based on (co-)variance targeting (VT). By de finition the VT estimator is a two-step estimator and the theory presented is based on expansions of the modifi ed likelihood function, or estimating function, corresponding to these two steps.

Revisiting EWMA in High‐Frequency‐Based Portfolio Optimization: A Comparative Assessment

Journal of Applied Econometrics, EarlyView.
ABSTRACT This paper compares the statistical and economic performance of state‐of‐the‐art high‐frequency (HF) based multivariate volatility models with a simpler, widely used alternative, the Exponentially Weighted Moving Average (EWMA) filter. Using over two decades of 100 U.S.

Variance Targeting Estimation of Multivariate GARCH Models [PDF]

Journal of Financial Econometrics, 2014
We establish the strong consistency and the asymptotic normality of the variance-targeting estimator (VTE) of the parameters of the multivariate CCC-GARCH($p,q$) processes. This method alleviates the numerical difficulties encountered in the maximization of the quasi likelihood by using an estimator of the unconditional variance. It is shown that
