Using a modified DCC-MIDAS specification that allows the long-term correlation component to be a function of multiple … explanatory variables, we show that the stock-bond correlation in the US, the UK, Germany, France, and Italy is mainly driven by … portfolios in terms of portfolio risk. While optimal daily weights minimize portfolio risk, we find that portfolio turnover and …
