No 4421, CESifo Working Paper Series from CESifo

Abstract: We examine how regularly scheduled macroeconomic announcements for the U.S., Germany and the euro area affect the German stock market, using high–frequency, minute–by–minute DAX data. Our study extends the literature on high–frequency announcement effects in several ways. First, we account for endogenous return dynamics by assessing announcement impacts via response analysis. Second, we examine the announcements effects on market volatility in a more detailed fashion by distinguishing effects of positive and negative surprises. Finally, we adapt the standard weighted–least–squares approach to more adequately analyze both conditional mean and volatility effects.
