We analyze interrelations between three stock markets in Central and Eastern Europe and, in addition, interconnections which may exist between Western European (DAX, CAC, UKX) and Central and Eastern European stock markets (BUX, PX-50, WIG20). The novelty of our paper rests mainly on the use of the five-minute tick intraday price data from the mid-2003 to the early 2005 for stock indices and on the wide range of econometric techniques employed. We find no robust cointegration relationship for any of the stock index pairs or for any of the extended specifications. There are signs of short-term spillover effects both in terms of stock returns and stock price volatility. Granger causality tests show the presence of bidirectional causality for returns as well as volatility series. The results based on a VAR framework indicate a more limited number of short-term relationships between the stock markets. In general, it appears that spillover effects are stronger from volatility to volatility than contagion effects from return to return series.
