- Are REITS hedge or safe haven against oil price fall?Publication . Hanif, Waqas; Andraz, Jorge; Gubareva, Mariya; Teplova, TamaraThis paper studies the hedge against falling oil prices and the safe haven properties of fourteen major country-specific real estate investment trusts (REITs) indices for the Asian, American, European, and worldwide geographies. Our analyses are performed from both, returns and conditional volatility perspectives. Our sample spans from January 2016 until August 2022, covering the COVID-19 pandemics and the ongoing Russia-Ukraine military conflict. We find that during COVID-19, only the Japan REITs, in terms of both returns and volatility, act as a hedge for oil whereas the only hedge during the Russia-Ukraine conflict is the Netherland REITs. In addi-tion, we document diverse degrees of safe-haven and diversifiers properties for REITS from diverse geographies along the full sample and the respective sub-samples for both bearish con-ditions and elevated volatility in the oil market. Our results imply that market regulators should focus on controlling volatility in crude oil and REITs markets, especially throughout times of financial distress, as daily return volatility monitoring is a pivotal requirement for optimized investment management. Our study provides important knowledge for investors, policymakers, and market regulators.
- How do GCC countries stocks interact with US and European debt markets?Publication . Hanif, Waqas; Khoury, Rim El; Gubareva, MariyaThis study conducts a comprehensive analysis of interconnectedness in Gulf Cooperation Council (GCC) equity markets and global bond markets, primarily focusing on European Monetary Union (EMU) and US bonds, from July 2007 to September 2023. Using innovative methodologies such as quantile connectedness and quantile coherency, we capture the dynamic relationships across different market conditions, particularly during extreme events. The quantile connectedness includes a moderate to low degree of interconnectedness during normal market conditions, intensifying during extreme market conditions. The United Arab Emirates (UAE) and Saudi Arabia are identified as influential players, transcending borders to impact returns in other GCC markets. Roles of GCC countries as net transmitters or receivers of returns shift over time, necessitating adaptable investment strategies. The interconnectedness of GCC markets with bonds responds differently to global crises and turbulences, including geopolitical and health crises. Our quantile coherence analysis provides insights for risk management and portfolio allocation. These findings have crucial implications for investors, encouraging adaptive asset allocation strategies, and for policymakers to monitor intra-regional spillovers in shaping market dynamics.
- Impacts of COVID-19 on dynamic return and volatility spillovers between rare earth metals and renewable energy stock marketsPublication . Hanif, Waqas; Mensi, Walid; Gubareva, Mariya; Teplova, TamaraWe examine the time-frequency co-movements and return and volatility spillovers between the rare earths and six major renewable energy stocks. We employ the wavelet analysis and the spillover index methodology from January 1, 2018 to May 15, 2020. We report that the COVID-19-triggered significant increase in co-movements and spillovers in returns and volatility between the rare earths and renewable energy returns and volatility. The rare earths act as net recipient of both return and volatility spillovers, while the clean energy stocks are net transmitters of return and volatility spillovers before and during the COVID-19 crisis. The solar and wind stocks are net transmitters/receivers of spillovers before/during the pandemic. The remaining markets shift from net spillover receivers to transmitters or vice versa; evidencing the effects of the pandemic. Our results show that cross-market hedge strategies may have their efficiency impaired during the periods of crises implying a necessity of portfolio rebalancing.
