Exploring portfolio diversification with alternative investments: An international TVP-VAR approach
This study examines the potential for portfolio diversification across a wide range of international assets, including equities, bonds, commodities, and alternatives like gold, Bitcoin, and real estate. Using 13 years of daily returns data from over 30 countries (MSCI indices) and employing time-varying parameter vector autoregressive (TVP-VAR) approach, we provide insights into the behavior of connectedness of these assets. The results indicate that the MSCI equity indices (i.e., MSCIWO, MSCNA, MSCIEU, MSCIPC) show strong interconnectedness and global influence, while bonds exhibit bidirectional volatility with equities. Brent and BCOM drive significant spillovers, especially to NG, while BDI remains isolated. Gold acts as a hedge, linking to commodities and bonds, whereas Bitcoin remains largely disconnected from traditional markets. These findings offer practical implications for investors, funds, banks, and policymakers seeking to optimize portfolio diversification.
期刊介绍:
Research in International Business and Finance (RIBAF) seeks to consolidate its position as a premier scholarly vehicle of academic finance. The Journal publishes high quality, insightful, well-written papers that explore current and new issues in international finance. Papers that foster dialogue, innovation, and intellectual risk-taking in financial studies; as well as shed light on the interaction between finance and broader societal concerns are particularly appreciated. The Journal welcomes submissions that seek to expand the boundaries of academic finance and otherwise challenge the discipline. Papers studying finance using a variety of methodologies; as well as interdisciplinary studies will be considered for publication. Papers that examine topical issues using extensive international data sets are welcome. Single-country studies can also be considered for publication provided that they develop novel methodological and theoretical approaches or fall within the Journal''s priority themes. It is especially important that single-country studies communicate to the reader why the particular chosen country is especially relevant to the issue being investigated. [...] The scope of topics that are most interesting to RIBAF readers include the following: -Financial markets and institutions -Financial practices and sustainability -The impact of national culture on finance -The impact of formal and informal institutions on finance -Privatizations, public financing, and nonprofit issues in finance -Interdisciplinary financial studies -Finance and international development -International financial crises and regulation -Financialization studies -International financial integration and architecture -Behavioral aspects in finance -Consumer finance -Methodologies and conceptualization issues related to finance
