Stock-Bond Return Dynamic Correlation and Macroeconomic Announcements : Time-Scale Analysis and the Effects of Financial Crises

We use wavelet analysis to examine the impact of macro-news announcements on the stock-bond correlation. Significant announcement effects appear after controlling for the recent financial crisis, with a link between the speed of reaction and the timing of announcements, with early released news exhibiting a slower effect. The news effects differ when we replace the 2008 crisis with the 2001 dot-com or 2011 government debt ceiling dispute periods. Tests involving small stocks, different model specifications, volatility effects and other robustness considerations continue to support our results. These results will enhance our understanding of the links between financial markets and the macroeconomy
