Abstract
Purpose
The aim of this study is to measure portfolio diversification benefits of the Turkey-based equity investors into top trading partner countries. Portfolio diversification benefits are analyzed from the viewpoint of two types of investors in Turkey: conventional equities investors and Islamic equity investors.
Design/methodology/approach
In order to evaluate the time-varying correlations of the trading partner country's stock index returns with the Turkish stock index returns, the multivariate-generalized autoregressive conditional heteroskedasticity–dynamic conditional correlation (GARCH-DCC) is applied based on daily data covering 13 years' period between January 22, 2008 and January 22, 2021.
Findings
The results revealed that the US stock indices provide the most diversified benefit for both conventional and Islamic Turkey-based equity investors. In general, Islamic indices exhibit relatively lower correlation with trading partners than conventional indices. Turkey and Russia are recorded as the most volatile indices.
Originality/value
The diversification potential in trading partners for Turkey-based Islamic equity investors has not been studied yet. This study is to fill in this gap in the literature and to give fruitful insights to both conventional and Islamic investors.

Abstract
Purpose
The purpose of this study is to investigate the impact of COVID-19 on conventional and Islamic stocks by using the data spanning from February 25, 2020, to February 3, 2021, and employing a panel regression approach.
Design/methodology/approach
In this study a panel regression approach has been used.
Findings
The study finds a negative association between COVID-19 and stock (both Islamic and conventional). After splitting the data into 1st and 2nd waves, the relationship between COVID-19 and stock (both Islamic and conventional) remains the same (negative) in the case of the 1st wave. In contrast, in the case of the 2nd wave, the relationship turned out to be positive. During both waves of the pandemic, the magnitude of the effect is found to be higher for conventional stocks. Additionally, the study also analyzes the aggregate influence of COVID-19 on different sectors and finds that commercial banks, oil and gas exploration and marketing companies are the most influenced sectors. At the same time, automobiles and pharma are the least affected sectors.
Practical implications
The study suggests that markets start gaining momentum to reach their prepandemic level after absorbing the initial shock (emergence of a pandemic). The study also provides thorough insights for market regulators and policymakers by implying the dynamic relations between markets (conventional and Islamic) and financial crisis, which would allow them more effective control of crisis in future endeavors.
Originality/value
This is one of the first studies to investigate the impact of COVID-19 on both conventional and Islamic stocks, especially in the context of Pakistan.

Abstract
Purpose
This study comprehensively aims to review the key influential and intellectual aspects of spillovers between Islamic and conventional financial markets.
Design/methodology/approach
The study uses the bibliometric and content analysis methods using the VOSviewer software to analyse 52 academic documents derived from the Web of Sciences (WoS) between 2015 and June 2022.
Findings
The results demonstrate the influential aspects of spillovers between Islamic and conventional financial markets, including the leading authors, journals, countries and institutions and the intellectual aspects of literature. These aspects are synthesised into four main streams: research between stock indexes; studies between stock indexes, oil and precious metal; works between Sukuk, bond and indexes; and empirical studies review. The authors also propose future research directions in spillovers between Islamic and conventional financial markets.
Research limitations/implications
Our study is subject to several limitations. Firstly, the authors only used the WoS database. Secondly, the study only includes papers and reviews written in English from the WoS. This study assists academic scholars, practitioners and regulatory bodies in further exploring the suggested issues in future studies and improving and predicting economic and financial stability.
Originality/value
To the best of the authors’ knowledge, no extant empirical studies have been conducted in this area of research interest.

Abstract
Purpose
This study aims to test mutual fund superiority, comparing the performance of 646 Islamic mutual funds with 475 ethical funds and conventional proxies.
Design/methodology/approach
This study uses statistical methods including paired t-statistics of independent samples, one-way Bonferroni test–analysis of variance–F-statistic for testing means equality, the chi-squared test for median equality and regression models corrected for heteroscedasticity. These methods are used to identify superiority of mutual funds and to validate the significance of the results.
Findings
The findings confirm the superiority of conventional funds over ethical funds and ethical funds over Islamic funds. Both ethical and Islamic funds, however, outperform conventional proxies during some recessionary periods. Moreover, stronger performance is recorded for Islamic funds in Europe and North America regions and across age and asset allocation categories, but limited support for reversal fund size, composition focus and reversed price effect.
Research limitations/implications
These findings should assist investors when deciding to invest and motivate Islamic and ethical funds to improve their portfolio formation and asset allocation strategies set by their professional managers.
Originality/value
The originality of this study is in its comprehensive approach in that it compares the performance of funds after accounting for such characteristics as fund objectives, size, age, asset allocation, geographical investment focus, fund composition focus, share price levels and the effect of global crises. This study approach is not only original and productive in documenting Islamic funds’ performance for the past three decades (1990–2022) but can also update the literature on these characteristics collectively and individually.

Abstract
Purpose
This study attempts to comprehensively analyze the cost Malmquist productivity index of conventional and Islamic banks in Saudi Arabia, the largest dual banking sector in the world, during the COVID-19 pandemic.
Design/methodology/approach
This study employs the novel approach of cost Malmquist productivity index, which focuses on production costs, to measure the change in cost productivity so that the actual impact of the COVID-19 pandemic could be captured.
Findings
The Saudi Central Bank has successfully mitigated the impact of the COVID-19 epidemic on the Saudi banking sector by implementing several policies and services. This success is reflected in the large positive shift in the production frontier of Saudi banks. Moreover, it was found that Islamic Saudi banks were by far more productive than conventional Saudi banks during the COVID-19 pandemic. However, the total cost productivity index (CMPCH) of Islamic Saudi banks starts to decline sharply in the last quarter of 2022 compared to conventional Saudi banks, indicating that Islamic banks in Saudi Arabia are suffering the most from the tighter monetary policy recently implemented by the Saudi Central Bank.
Practical implications
The results provide insights for policymakers and investors on how different types of banks respond differently to economic crises and monetary policy changes. Targeted support measures may be needed to ensure all banks remain productive and efficient.
Originality/value
To the author’s knowledge, this is the first study to use this innovative methodology to assess the impact of COVID-19 on bank performance in a dual banking sector.

Abstract
Purpose
The purpose of this paper is to build a relationship between the quantitative and structural indicators of maqashid sharia studies produced from bibliometric analysis and the conceptual discussion developed through a thorough review of selected key literature.
Design/methodology/approach
The study uses bibliometric analysis, collecting information drawn from 219 articles published in 68 journals during the period of 2006–2022. This study uses VOSviewer, RStudio, Microsoft Excel, and an examination of research time periods using the Scopus database to illustrate the citation analysis and keyword map. It is also strengthened by content analysis of selected studies.
Findings
The main research theme found in this study is the application of maqashid sharia in Islamic banks, with Islamic banks and Islamic finance among the most frequently used keywords. Meanwhile, the geographical spread of maqashid sharia research has reflected its universal acceptance, as it has spread across both Muslim-dominant and non-Muslim-dominant countries. Besides, maqashid sharia is found to be an extremely important subject for ensuring the ethical dimension of Islamic finance products and services, a more inclusive human development index, and contributing to the international agenda of Sustainable Development Goals. Lastly, future research is expected to broaden it into a multi-dimensional horizon, with several recommendations offered to enrich the understanding of maqashid sharia.
Practical implications
The findings of this study can be beneficial to multiple stakeholders in Islamic finance industry, including the management of Islamic banks, who can enhance the values of maqashid sharia in designing their products/services, and the regulators, who can formulate regulatory frameworks which are reflective of maqashid sharia principles.
Social implications
This study will assist future scholars in this field to formulate and design exciting research ideas and models to address the deficiencies found in the current implementation of maqashid sharia within Islamic finance industry.
Originality/value
The primary contribution of this study is to provide comprehensive review and discussion of selected significant literature on maqashid sharia and give direction for future research. In addition, this study also extends and incorporates the results of bibliometrics using the recent maqashid sharia studies published at the end of 2022.

Abstract
Purpose
This paper aims to analyze the connectedness between Gulf Cooperation Council (GCC) stock market index and cryptocurrencies. It investigates the relevant impact of RavenPack COVID sentiment on the dynamic of stock market indices and conventional cryptocurrencies as well as their Islamic counterparts during the onset of the COVID-19 crisis.
Design/methodology/approach
The authors rely on the methodology of Diebold and Yilmaz (2012, 2014) to construct network-associated measures. Then, the wavelet coherence model was applied to explore co-movements between GCC stock markets, cryptocurrencies and RavenPack COVID sentiment. As a robustness check, the authors used the time-frequency connectedness developed by Barunik and Krehlik (2018) to verify the direction and scale connectedness among these markets.
Findings
The results illustrate the effect of COVID-19 on all cryptocurrency markets. The time variations of stock returns display stylized fact tails and volatility clustering for all return series. This stressful period increased investor pessimism and fears and generated negative emotions. The findings also highlight a high spillover of shocks between RavenPack COVID sentiment, Islamic and conventional stock return indices and cryptocurrencies. In addition, we find that RavenPack COVID sentiment is the main net transmitter of shocks for all conventional market indices and that most Islamic indices and cryptocurrencies are net receivers.
Practical implications
This study provides two main types of implications: On the one hand, it helps fund managers adjust the risk exposure of their portfolio by including stocks that significantly respond to COVID-19 sentiment and those that do not. On the other hand, the volatility mechanism and investor sentiment can be interesting for investors as it allows them to consider the dynamics of each market and thus optimize the asset portfolio allocation.
Originality/value
This finding suggests that the RavenPack COVID sentiment is a net transmitter of shocks. It is considered a prominent channel of shock spillovers during the health crisis, which confirms the behavioral contagion. This study also identifies the contribution of particular interest to fund managers and investors. In fact, it helps them design their portfolio strategy accordingly.

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
This study aims to empirically explore and compare the dynamic dependency between health-care sector and Islamic industries before, during and after the COVID-19 pandemic.
Design/methodology/approach
Time-varying student-t copula is used for before, during and after COVID-19 periods. The data used are the daily frequency price series of the selected markets from February 2017 to October 2023.
Findings
Empirical results found strong evidence of significant impact of the COVID-19 pandemic on the dependence structure of the studied indexes: Co-movements between various sectors are certain. The authors assist also in the birth of new dependence structure with the health-care industry in response to the COVID-19 crisis. This reflects the contagion occurrence from the health-care sector to other sectors.
Originality/value
By specifically examining the Islamic industry, this study sheds light on the resilience, challenges and opportunities within this sector, contributing novel perspectives to the broader discourse on pandemic-related impacts on economies and industries. Also, this paper conducts a comprehensive temporal analysis, examining the dynamics before, during and after the COVID-19 lockdown. Such approach enables an understanding of how the relationship between the health-care sector and the Islamic industry evolves over time, accounting for both short-term disruptions and long-term effects. By considering the pre-pandemic context, the paper adopts a longitudinal perspective, enabling a deeper understanding of how historical trends, structural factors and institutional frameworks shape the interplay between the health-care sector and the Islamic industry.

Abstract
Purpose
This study aims to investigate the relationship between Islamic governance and the social performance of Islamic banks, pioneering a new aspect in terms of the impact of the National Shariah Board (NSB) on the social performance of Islamic banks. The essential body in the Islamic banks in charge of Islamic governance is the Shariah Supervisory Board (SSB). Therefore, in this study, the authors explore how the characteristics of the Shariah board and Islamic governance mechanisms influence the social performance of Islamic banks.
Design/methodology/approach
Panel data methods are applied to the annual data of 43 banks from 14 countries over the period 2012–2018 to explore the impact of Islamic governance on Islamic banks’ social performance. The authors have used all available bank annual reports in the given period. Social performance is measured by Maqasid al-Shariah (in terms of the goals of the Islamic moral economy) index using a comprehensive evaluation framework. Islamic governance is represented by the improved Islamic Governance Score (IG-Score) index, which measures the quality of Islamic governance in Islamic banks. In the research, the authors also introduce the frequency of SSB meetings in IG-Score.
Findings
The findings suggest a strong link between Islamic governance and the social performance of Islamic banks, illustrating the importance of the Shariah board in achieving maqasid. On the other hand, the research discovered that NSBs are inefficient and the existence of NSB can jeopardize the social performance of Islamic banks. The results of this research imply valuable recommendations for Islamic banks that are keen to improve their social performance.
Originality/value
Besides investigating the impact of SSB governance on the social performance of Islamic banks by using an improved IG score index, to the best of the authors’ knowledge, this is the first study that investigates the impact of NSBs on the social performance of Islamic banks.
