The Reaction Of Asset Prices To Macroeconomic Announcements In New EU Markets: Evidence From Intraday Data

The authors estimate the impact of macroeconomic news on composite stock returns in three emerging European Union financial markets (the Budapest BUX, Prague PX-50, and Warsaw WIG-20), using intraday data and macroeconomic announcements. Their contribution is twofold. They employ a larger set of macroeconomic data releases than used in previous studies and also use intraday data, an excess impact approach, and foreign news to provide more reliable inferences. Composite stock returns are computed based on five-minute intervals (ticks) and macroeconomic news are measured based on the deviations of the actual announcement values from their expectations.
