We analyze foreign news and spillovers in the emerging EU stock markets (the Czech Republic, Hungary, and Poland). We employ high-frequency five-minute intraday data on stock market index returns and four classes of EU and US macroeconomic announcements during 2004-07.
We account for the difference of each announcement from its market expectation and we jointly model the volatility of the returns accounting for intraday movements and day-of-the-week effects.
