An Econometric Analysis of ETF and ETF Futures in Financial and Energy Markets Using Generated Regressors

Abstract

Abstract:It is well known that there is an intrinsic link between the financial and energy sectors, which can be analysed through their spillover effects, which are measures of how the shocks to returns in different assets affect each other's subsequent volatility in both spot and futures markets. Financial derivatives, which are not only highly representative of the underlying indices, but can also be traded on both the spot and futures markets, include Exchange Traded Funds (ETFs), a tradable spot index whose aim is to replicate the return of an underlying benchmark index. When ETF futures are not available to examine spillover effects, "generated regressors" are useful for constructing both financial ETF futures and energy ETF futures. The purpose of the paper is to investigate the co-volatility spillovers within and across the U.S. energy and financial sectors in both spot and futures markets, by using "generated regressors" and a multivariate conditional volatility model, namely diagonal BEKK. The daily data used are from 23 December 1998-22 April 2016. The dataset is analysed in its entirety and is also subdivided into three distinct subsets. The empirical results show there is a significant relationship between the financial ETF and energy ETF in the spot and futures markets. Therefore, financial and energy ETFs are suitable for constructing a financial portfolio from an optimal risk management perspective and also for dynamic hedging purposes.

Is Technical Analysis Profitable on Renewable Energy Stocks? Evidence from Trend-Reinforcing, Mean-Reverting and Hybrid Fractal Trading Systems

“…It also reported that the strength of the renewable power portfolios continues even with the advent and the recovery period of the COVID-19 crisis. The positive performance of renewable power portfolios is also documented in several academic research studies, such as those of Chang et al [4] and Chang et al [5]. These studies employed technical analysis and found superior returns for renewable energy stocks against fossil energy markets in the US and Europe.…”

A Review On the Nexus between Energy industry, Financial Markets, Environmental Concerns, and Geopolitics

“…Existing literature [1] investigates the relationship between Financial ETF and Energy ETF, testing spillover effects among ETF and ETF futures and conducting empirical analysis for several sub-periods. Among others, they find that financial and Energy ETFs are suitable for constructing a financial portfolio from optimal risk management perspective.…”

Application of Diffusion Models in the Analysis of Financial Markets: Evidence on Exchange Traded Funds in Europe

“…The only exception is the analysis of the Asia-Pacific markets presented in Marszk et al (2019)-due to different geographical coverage, it cannot be compared directly to the current study. In the recent years, there have been a number of studies devoted to the relationships between ETFs and futures but they have focused on particular attributes of selected instruments rather than market-broad analysis (e.g., Liu and Tse 2017;Oztekin et al 2017;Chang et al 2018;Wang et al 2018;Chang et al 2019;Jiang et al 2019;Wallace et al 2019;Liu et al 2020).…”
