How much of the total variation of the 10-year bond bid yields can be explained by the announcements? Are “good” news capable of explaining more of the variation of the bonds than “bad” news? These are all relevant questions to ask as the announcement sources and country bond combinations present in this dissertation are often ignored by the literature. This dissertation finds that for this sample, announcements from the USA are the ones with the most explanatory power, explaining on average 8.7%, of the daily variation, furthermore we also find that Eurozone announcements have close to none explanatory power on the daily variation of the 10 years bond bid yields, lastly we find that “good” news have a greater explanatory power then “bad” news.engMacroeconomic announcementsEurozoneGovernment bondsmaster thesis201463490
