The existing literature have evaluated the performance of stock markets without taking into account the time-varying correlations and different investment horizons of the investors. The present paper attempts to investigate to what extent the Indonesian sharia stock returns can earn portfolio diversification benefits if they are trading with sharia stocks from its major trading partners (China, Japan, United States). The recent Multivariate GARCH Dynamic Conditional Correlation, the Continuous Wavelet Transform and the Maximal Overlap Discrete Wavelet are applied. Our findings tend to indicate that the Indonesian investors may not enjoy portfolio diversification benefits in all investment horizons if investing in China as better investment opportunities are available by investing in Japan and United States. However, in the long run all markets are highly correlated yielding minimal portfolio diversification benefits.
