This paper is the first attempt to investigate the multiscale tendency of the co-movement and cross-correlation of nine Islamic Exchange Traded Fund (ETF) returns across the global developed and emerging markets using both wavelet coherence and wavelet MODWT methods. The wavelet coherence results tend to indicate consistent co movement between most of the ETF returns especially in the long run. The study also uncovers evidence of wide variation of co-movement across the time-scales during the global financial crisis and the Euro debt crisis. Strong co-movement can be observed during the global financialcrisis, both for the medium term investors and long term investors. The paper studies the relationship between different ETF returns using wavelet multi-resolution analysis. The cross-correlation analysis also shows certain significant and positive correlations between the ETF returns, especially during the period of global financial crisis. The findings from these two recent dynamic time-scale decomposition methodologies have important policy implications for both risk management and investors’ investment policy.

This study constructs active Islamic portfolios using a multi-style rotation strategy, derived from the three prominent styles, namely, momentum, value, and quality investing. We use the stocks that are consistently listed in the U.S. Dow Jones Islamic index for a sample period from 1996 to 2012. We also include two macroeconomic mimicking portfolios to capture the premiums of industrial production growth and inflation innovation, accommodating the economic regime shifts. Based on the information coefficients, we find the six-month momentum and the fractal measure as momentum factors; the enterprise yield (gross profit/TEV) and the book to market ratio as valuation factors; the gross profit to total assets, the return on capital, and the scaled total accruals as quality factors. We further construct active portfolios using the augmented Black Litterman (ABL) factor model to avoid the factor alignment problem, with the factor views predicted using Markov Switching VAR, MIDAS, and Bayesian Model Averaging. The out-of-sample performance of our portfolios can produce information ratios of 0.7–0.8 over the composite indices, and information ratios of 0.42–0.48 over the style indices, with the annualized alphas of 10–11%. Even when we put the constrained tracking error of 1% over the benchmark, our portfolios still produce information ratios of 0.9–1.2 before transaction costs, and 0.6–0.8 after transaction costs. We provide intuitive explanations for each premium changing over time, and suggest the promising strategy for Islamic equity investors to outperform the market.

The global Islamic finance industry has evolved from a small industry to a dynamic, robust, and competitive one. Currently, the industry, built on the notion of justice and fairness, has a global asset size of approximately USD2 trillion (MIFC, 2016). Despite the soft global economic outlook, this industry is expected to grow as many more nations are embracing this alternative system that is proven to be not only profitable but also resilient to macroeconomic shocks.

The purpose of this paper is to examine the extent to which the Indonesian Shariah compliant investors can benefit from the portfolio diversification with the Islamic indices of its trading partners and selected commodities such as gold, crude oil, and cocoa. The findings tend to indicate that investors with exposure in Shariah compliant indices of Indonesia and wanting to gain more diversification benefits should invest either in the USA or India Islamic equity. Instead, the greater benefits will be obtained by Shariah compliant investors if they invest in the USA Islamic indices during long-term investment horizons. If investors want to invest in medium investment horizons, investing in India Islamic equity is a viable option. The findings further suggest that gold has a role of diversification benefits as a "safe haven" instrument for investors. It is advisable for the investors that have exposure in commodities (gold, crude oil, and cocoa) and want to invest in Indonesian Islamic equity, they should hold the portfolio for not more than 16 days to gain diversification benefits.
