This paper investigates the spillover impact of US unconventional monetary
policy and uncertainty factors on the time-varying co-movements between the
US stock market and 14 advanced countries? bond markets, as based on monthly
data from January 2002, to October 2015, and utilising the conditional
nonlinear quantile regression approach. The empirical results reveal that US
unconventional monetary policy has an asymmetric positive effect on
stock-bond market co-movements, with a nonlinear effect in France and
Denmark and a strong effect in the UK and Finland. Further, US bond market
uncertainty has heterogeneous effects on stock-bond market co-movements,
with a nonlinear effect in France and Denmark and a strong effect in Finland
and Sweden. In addition, default risk spread positively influences
stock-bond market comovements across most countries for all quantiles. In
contrast, stock-bond market co-movements negatively and symmetrically
respond to the US stock market uncertainty in most countries. Finally,
stock-bond co-movements exhibit mixed responses to US economic policy
uncertainty across countries. Our results have valuable implications for
international investors who allocate capital across developed countries?
stock and bond markets. Our findings provide important information for
financial communities with regard to diversification and hedging.
