The recent COVID-19 pandemic or Global Health Crisis (GFH) has distorted the normal functioning of the global economies and financial markets. Previous research has shown that Islamic equities were relatively more stable than conventional ones during the 2008 Global Financial Crisis (GFC). So, this study aims to assess the effect of the COVID-19 pandemic on the performance and co-movement of the leading Islamic finance markets by employing MGARCH-DCC on daily frequency data spanning from January 01, 2017 to October 22, 2021. The findings suggest that, as expected, the pandemic outbreak has increased the volatility across the sample markets, but it faded relatively soon, indicating that Islamic equities carry hedging features and offer portfolio diversification benefits to investors. Moreover, the sample countries are less correlated during the sample period than expected. The findings have important implications for policymakers and diverse investors deciding on portfolio diversification. Global ethical and Islamic investors, including fund managers, could benefit by focusing on more stable markets and building optimal portfolios of Shari'ah-complaint equities during turbulent market conditions, such as the COVID-19 pandemic.

Purpose: The purpose of this paper is to investigate the extent to which Chinese equity investors can benefit from diversifying their portfolio into Shariah-compliant (Islamic) indices. It examines three Islamic stock indices (FTSE Shariah China price index, MSCI China Islamic IMI price index and the DJ Islamic Greater China price index) and ten sectoral indices in Shanghai Stock Exchange as a sample. Design/methodology/approach: The multivariate GARCH dynamic conditional correlations (MGARCH-DCC) is deployed to estimate the time-varying linkages of returns of the selected indices, covering approximately eight years daily data starting from 28 August 2009 to 29 September 2017. Findings: In general, in terms of volatility, the results indicate that all Islamic Indices are less volatile than the conventional indices. From the correlation analysis, the results imply that Chinese conventional equity investors would benefit from Islamic stock indices, especially when they include DJ Islamic Greater China in their portfolio. Originality/value: The findings of this paper may have several significant implications for the Chinese equity investors and fund managers for better understanding about co-movements of the Chinese conventional sectoral indices with the Shariah-compliant stock indices with the purpose of gaining higher risk-adjusted returns through portfolio diversification.
