Stocks are soaring on the prospect of a vaccine for COVID-19 being available by the end of the month - nothing more. 

As to Trump being unliked by global investors, that sounds like opinion, and in my opinion you are very wrong.  I would argue that the best possible scenario for global investors is a strong and viable US economy.  Having said that, I also expect a recession or worse within the next two or so years.  Whoever is in office at that time, a downturn can only be made worse by Liberals.  John Kennedy was the only Dem to bring about an economic boom, but that was because he adopoted the Republican principle of lower taxes overall (as did Trump).  Biden promises the opposite.  Is that not a fact?
