This study analyses and compares the dynamics of intra-European Monetary Union and intra-non-EMU, EU stock markets' return
spillover during European Sovereign Debt Crisis (2 November 2009 to 30 December 2016). Diebold and Yilmaz's (Int J Forecast
28(1):57-66, 2012) spillover index, Barunik's et al. (J Int Money Finance 77:39-56, 2017) spillover asymmetry measures, and
Barunik and Krehlík's (J Financ Econ 16(2):271-296, 2018) frequency connectedness methodologies are applied for analysis.
The findings of this study indicate that intra-EMU stock market return spillover was higher than the intra-non-EMU EU stock
markets' return spillover during the crisis period. It is also identified that the intra-EMU stock market return spillover
is more responsive to global and domestic economic and financial events than to the intra-non-EMU EU stock markets' return
spillover. France was identified as the most integrated and Slovakia the least integrated among the EMU stock markets. Among
the non-EMU EU stock markets, Sweden was identified as the most integrated and Bulgaria as the least integrated stock market
with other non-EMU EU stock markets. The presence of asymmetry in the return spillover for both EMU and non-EMU, EU stock
markets was also revealed. It was also found that return spillover among the EMU and non-EMU, EU stock market is dominated
over higher frequencies and that stock markets in these economies analyse information rapidly to incorporate it into stock
prices. The findings of the study provide significant implications for researchers, academician and policy-makers. Knowledge
regarding the dynamics of return spillover among the investigated stock markets will allow investors to formulate their portfolio
diversification strategies in a better and informed manner.
