Diversification benefits of domestic and international REITs for SET Index before and during Covid-19 crisis

Abstract

This study examines the diversification benefit of Thailand, the US, Europe, Singapore, and Japan REIT indices for the SET index. The time scope for this study starts from 1st January 2011 to 31th January 2022. It also compares the diversification benefit degree between pre and during Covid-19 periods. The DCC-GARCH model is used for the diversification benefit examination. The results posit 3 main points. First, all the REIT indices provide diversification benefit for the SET index. Second, the Covid-19 pandemic reduces diversification benefit generated by the US, Europe, and Japan REIT indices. Finally, the US provides the highest diversification benefit to the SET index among the others.
