Abstract: We examine the portfolio implications of adding the Islamic bond index (Sukuk) to a benchmark portfolio of Islamic stocks. The daily data of the Islamic bond index; the Islamic stock markets of the world, Canada, Japan, USA, UK and Islamic financial stocks are used for the period of 1 October 2005 through 30 April 2015. We examine the presence of structural breaks via the Iterated Cumulative Sum of Square (ICSS) algorithm, which clearly indicate that Islamic stock-bond returns have several structural breaks over the sample period; hence, the dependence among the markets may have a regime-switching pattern. We rely on the flexible properties of the ARMA-FIGARCH models with the skew-t distribution to model the marginal distributions of the series. Next, a set of static, time-varying and regime-switching time-varying copula models are applied to encircle the dependence dynamics. Finally, using different portfolio strategies, we access the portfolio implications of a multi-asset portfolio. Overall, the results provide evidence that the Islamic bond index can be included as a potential hedge/safe haven in benchmark stock portfolios.
