Abstract

Purpose

Market links (and price discovery) between financial assets and lead–lag relationships are topics of interest for financial economists, financial managers and analysts. The lead–lag relationship analysis should consider both short and long-term investors. From a portfolio diversification perspective, the first type of investor is generally more interested in determining the co-movement of financial assets at higher frequencies, which are short-run fluctuations, while the latter concentrates on the relationship at lower frequencies, or long-run fluctuations. The paper aims to discuss these issues.

Design/methodology/approach

For this study, a technique was employed known as the wavelet approach, which has recently been imported to finance from engineering sciences to study the co-movement dynamics between global sukuk and bond markets. Data cover the period from January 2010 to December 2015.

Findings

The results indicate that: there is no unidirectional causality from developed market bond indices to Malaysia and Dow Jones indices, which is promising for fixed-income investors of a developed market; and in relation to emerging markets, the Malaysian sukuk market has a bidirectional causality with Indonesia, Malaysia, India and South Korea bond indices but not China bond indices, while in terms of the Dow Jones sukuk index, there is no unidirectional causality between the listed emerging markets and the sukuk index except Indonesia’s market during the sample period.

Research limitations/implications

This analysis provides evidence regarding the timely and appropriate measure of correlation changes and the behaviour of sukuk and bond indices globally, which is beneficial to the management of sukuk and bond portfolios.

Originality/value

The evidence hitherto unexplored, which was produced by the application of a wavelet cross-correlation amongst the selected sukuk and bond indices, provides robust and useful information for international financial analysts as well as long and short-term investors.

Abstract

Purpose

This paper aims to examine the dynamic conditional correlation (DCC) and hedging ratios between Dow Jones markets and oil, gold and bitcoin. Using daily data, including the COVID-19 pandemic and the Russia–Ukraine war. We employ the DCC-generalized autoregressive conditional heteroskedasticity (GARCH) and asymmetric DCC (ADCC)-GARCH models.

Design/methodology/approach

DCC-GARCH and ADCC-GARCH models.

Findings

The most of DCCs among market pairs are positive during COVID-19 period, implying the existence of volatility spillovers (Contagion-effects). This implies the lack of additional economic gains of diversification. So, COVID-19 represents a systematic risk that resists diversification. However, during the Russia–Ukraine war the DCCs are negative for most pairs that include Oil and Gold, implying investors may benefit from portfolio-diversification. Our hedging analysis carries significant implications for investors seeking higher returns while hedging their Dow Jones portfolios: keeping their portfolios unhedged is better than hedging them. This is because Islamic stocks have the ability to mitigate risks.

Originality/value

Our paper may make a valuable contribution to the existing literature by examining the hedging of financial assets, including both conventional and Islamic assets, during periods of stability and crisis, such as the COVID-19 pandemic and the Russia–Ukraine war.

Abstract

Purpose

There is a great deal of research that has been done to investigate the investment characteristics of conventional socially responsible investment portfolios compared to their broader conventional counterparts. However, the impact of incorporating sustainability criteria into the traditional Sharia screening process has not so far been investigated. Therefore, the study aims to give empirical evidence as to whether or not incorporating sustainability socially responsible criteria in the traditional Sharia screening process has a significant impact on the investment characteristics of the Islamic investment portfolio.

Design/methodology/approach

The paper examines the investment characteristics of four groups of investment portfolios mainly, Dow Jones Global Index, Dow Jones Sustainability World Index, Dow Jones Islamic Market World Index and Dow Jones Islamic Market Sustainability Index. To improve the robustness of the study, the analysis was carried out at different levels. First, absolute mean return and t‐test were used to examine whether the difference between the different groups of investments is statistically significant or not. Second, risk adjusted equilibrium models, both single‐index and Fama and French multi‐index, were employed. This is to control for different risk exposure and investment style bias associated with different investment portfolios examined.

Findings

The paper finds that neither the Sharia nor the sustainability screening process seems to have an adverse impact on the performance and systematic risk of the investment portfolios compared to their unrestricted conventional counterparts. Therefore, Muslim as well as socially responsible investors can choose investments that are consistent with their value systems and beliefs without being forced to sacrifice performance or expose to higher systematic risk.

Originality/value

The study contributes to the existing literature by giving new evidence on the impact of incorporating sustainability criteria into the traditional Sharia screening process that has not so far been investigated.

Abstract

Purpose

In this study, the authors analyze the impact of geopolitics risk on Sukuk, Islamic and composite stocks, oil and gold markets and portfolio diversification implications during the COVID-19 pandemic and Russia–Ukraine conflict period.

Design/methodology/approach

The study used a mix of wavelet-based approaches, including continuous wavelet transformation and discrete wavelet transformation. The analysis used data from the Geopolitical Risk index (GP{R), Dow Jones Sukuk index (SUKUK), Dow Jones Islamic index (DJII), Dow Jones composite index (DJCI), one of the top crude oil benchmarks which is based on the Europe (BRENT) (oil fields in the North Sea between the Shetland Island and Norway), and Global Gold Price Index (gold) from May 31, 2012, to June 13, 2022.

Findings

The results of the study indicate that during the COVID-19 and Russia–Ukraine conflict period geopolitical risk (GPR) was in the leading position, where BRENT confirmed the lagging relationship. On the other hand, during the COVID-19 pandemic period, SUKUK, DJII and DJCI are in the leading position, where GPR confirms the lagging position.

Originality/value

The present study is unique in three respects. First, the authors revisit the influence of GPR on global asset markets such as Islamic stocks, Islamic bonds, conventional stocks, oil and gold. Second, the authors use the wavelet power spectrum and coherence analysis to determine the level of reliance based on time and frequency features. Third, the authors conduct an empirical study that includes recent endogenous shocks generated by health crises such as the COVID-19 epidemic, as well as shocks caused by the geopolitical danger of a war between Russia and Ukraine.

Highlights

  1. We analyze the impact of geopolitics risk on Sukuk, Islamic and composite stocks, oil and gold markets and portfolio diversification implications during the COVID-19 pandemic and Russia–Ukraine conflict period.

  2. The results of the wavelet-based approach show that Dow Jones composite and Islamic indexes have observed the highest mean return during the study period.

  3. GPR and BRENT are estimated to have the highest amount of risk throughout the observation period.

  4. Dow Jones Sukuk, Islamic and composite stock show similar trend of volatility during the COVID-19 pandemic period and comparatively gold observes lower variance during the COVID-19 pandemic and Russia–Ukraine conflict.

Abstract

Purpose

This paper aims to compare and analyse the aspects of Shariah screening methodologies within the selected Gulf Cooperation Council (GCC) countries as well as comparing the methodologies with the USA, and to examine how Shariah screening methodologies affect financing and investing activities of a firm.

Design/methodology/approach

Shariah screening methodologies within the selected GCC countries and between the GCC countries and the USA are compared on the basis of the data collected from secondary sources.

Findings

Design, qualification and Shariah governance set the Shariah screening methodologies within the GCC countries apart. Feasibility, duration, economic viability and funds required differentiate these Shariah screening methodologies between the GCC countries and the USA. Shariah screening methodologies implied in the USA is more stringent than in the GCC countries.

Research limitations/implications

The suggestions in this study include using a longer research timeline, examining many more number of countries’ Shariah screening methodologies and exploring other types of Shariah screening methodologies.

Practical implications

The possibility of generalising the implementation of strict and uniform Shariah screening methodologies across all the country-specific Shariah indices amongst Muslim nations, globally, is likely to benefit all the Muslim countries, by strengthening the understanding, interaction and economic co-operation amongst these countries.

Social implications

People’s needs can be tended to if Maqasid Al-Shariah (objectives of Shariah) is achieved through flexibility, dynamism and creativity within the social policy.

Originality/value

Aspects of Shariah screening methodologies are compared and contrasted within the selected GCC countries as well as between the GCC countries and the United States and the role of Shariah screening methodologies is examined in order to determine the extent of what is Shariah-Compliant and what is Non-Shariah Compliant for a firm.

Abstract

Purpose

The purpose of this paper is to test the existence of stylized facts, such as the volatility clustering, heavy tails seen on financial series, long-term dependence and multifractality on the returns of four real estate indexes using different types of indexes: conventional and Islamic by comparing pre and during COVID-19 pandemic.

Design/methodology/approach

Firstly, the authors examined the characteristics of the indexes. Secondly, the authors estimated the parameters of the stable distribution. Then, the long memory is detected via the estimation of the Hurst exponents. Afterwards, the authors determine the graphs of the multifractal detrended fluctuation analysis (MF-DFA). Finally, the authors apply the WTMM method.

Findings

The results suggest that the real estate indexes are far from being efficient and that the lowest level of multifractality was observed for Islamic indexes.

Research limitations/implications

The inefficiency behavior of real estate indexes gives us an idea about the prediction of the behavior of future returns in these markets on the basis of past informations. Similarly, market participants would do well to reassess their investment and risk management framework to mitigate new and somewhat higher levels of risk of their exposures during the turbulent period.

Originality/value

To the authors’ knowledge, this is the first real estate market study employing STL decomposition before applying the MF-DFA in the context of the COVID-19 crisis. Likewise, the study is the first investigation that focuses on these four indexes.

Abstract

Purpose

In recent times, sustainable investment gaining much attention within the investors’ community and it is broadly driven by environmental, social and governance (ESG) factors. This study aims to examine the ESG-based sustainability index and economic policy uncertainty (EPU).

Design/methodology/approach

Corporate sustainability assessment procedure yields Dow Jones sustainability indexes (DJSIUS) and ESG compliant firms become a member of such indexes. To uncover the effects of policy uncertainty as follows: the study considers EPU index, equity market policy uncertainty index, economic and political events for the period 2000–2017. The authors present the study using a conditional volatility framework.

Findings

The correlation between the DJSIUS and policy uncertainty appears to be negative and statistically significant. It is apparent from the results that policy uncertainty does contain important ESG factors that explain the sustainable investment in US firms. Moreover, the stock market boom, credit crunch, Lehman collapse and fiscal crises have shown significant adverse effects on the sustainability index. More importantly, it is seen that investors’ sustainable investing considers presidential election years for portfolio planning; the uncertainty associated with the election years has also shown a negative impact on the sustainable returns.

Practical implications

First, sustainability is essential for the long-term stakeholders’ wealth maximization under governments’ policy uncertainty such as constrained resources, demographic and climate-change-policy, societal expectations, public-policies, regulatory structure. Second, EPU creates new opportunities and risks for sustainable firms and sustainable investing.

Originality/value

The study is novel in which the authors present the effects of uncertainty on socially responsible investing.

Abstract

The authors consider a group of commercial vendors who may be potential agents or players in electronic document supply. The group examines five potential providers of products/services: Dow Jones, Geac, OCLC, Faxon, RLG using Malone's 1989 comments on electronic markets as a framework, and using Porter's analytics to describe competition, and the role of technology in conferring advantage. The authors suggest that electronic document supply has produced an observable shift in exchange relationships between suppliers and buyers: the former are regrouping into partnerships which offer a confusing range of options to clients.

Abstract

This chapter examines the framing of the Black Lives Matter (BLM) Movement in mainstream media. An analytic sample of 4,303 articles collected from the Dow Jones Factiva database reveals variation in depth, breadth, and intensity of BLM coverage in the following newspapers between 2012 and 2016: The St. Louis Post-Dispatch, The New York Times, The Washington Post, The Wall Street Journal, and Al Jazeera English. We review contemporary literature on racial inequality and employ Media Framing and Critical Race Theory to discuss the implications of our findings on public perceptions, future policy formation, and contemporary social protest worldwide.

Abstract

Purpose

The purpose of this study is to analyse different factors behind the disclosure of corporate information on issues related to greenhouse gas emissions and climate change world‐wide.

Design/methodology/approach

The empirical analysis carried out was performed in two stages: analysis of the data obtained through content analysis and analysis of the factors that influence the disclosure of greenhouse gas emissions and climate change using a dependency model, a multiple linear regression. Several variables were introduced to represent the size of the companies, leverage, return on assets (ROA), return on equity (ROE) and Market‐to‐Book ratio. Also, other dummy variables have been incorporated: Kyoto Protocol, activity sector in which the company operates and inclusion in the Dow Jones Sustainability Index.

Findings

The results obtained show a direct relationship between corporate size, its market capitalization and the disclosure of information in addition to proposed Global Reporting Initiative (GRI) indicators on greenhouse gas emissions. Conversely, an inverse relationship between ROE and disclosure is detected.

Practical implications

The findings emphasize that the main quoted companies operating in industries related to greenhouse gas emissions typically reveal information on almost all the GRI core indicators as well as the additional items specifically proposed for this issue. Moreover, the results suggest a trend for companies to utilize information on greenhouse gas emissions as a mechanism that enables them to legitimise themselves with those groups that can be of benefit to them.

Originality/value

The paper has analysed the disclosure of greenhouse gas emissions and other information of importance to climate change in companies from different countries, some of which have ratified, approved, adhered to or accepted the Kyoto Protocol, and some of which have still not accepted it.
