This study aims to evaluate adaptive hedging strategies for the oil–stock nexus in the Asia-Pacific region. This study also aims to compare management policies for risk spillover across M-GARCH models, focusing on findings from emerging and advanced nations.
The study used a novel integration of DCC-GARCH, GO-GARCH, aDCC-GARCH and EGARCH-DCC to build hedging strategies. Meanwhile, analysis of structural breaks shows that the different global crises have altered the linkages in the oil–stock nexus.
Outcomes revealed that GO-GARCH is suitable for conservative investors. DCC-GARCH and aDCC-GARCH are more responsive to active investors. EGARCH-DCC offers a balance between stability and sensitivity. Oil is the most effective hedging strategy for stocks in Singapore, and the least effective in the Philippines. Optimal allocations with oil reveal a preference in Vietnam and a low weight in Malaysia. Structural breakpoints analysis highlights decision-making in Singapore, India and Vietnam.
Future research may be expanded to other regions and higher frequencies. This research aims to assist participants in refining risk management across both long- and short-term crises, in line with each M-GARCH model.
The study makes a novel contribution by using various multivariate GARCH volatility models to allocate oil–stock nexus volatility across the Asia-Pacific region. Certain breakpoints and specific dates across multiple indices in different countries highlight the link between financial markets’ reactions and the global crisis.
