The only election outcome that will hurt the market (and no, biden winning will not hurt the market after the election) is if Trump loses, then declares the election to have been "a fraud" against him, declares it invalid,the supreme court knocks that down,but allows states to not send electoral college delagates if they believe fraud in the election (GOP controled legislatures in states that biden win could do that),then Biden will not get enough votes in the electoral college to win.
It then goes to the congress, where every state delegation gets one vote. 26 states are GOP controlled.
Then, the market tanks big time, as a trump win like that, with a dem congress and senate, will hurt the economy terribly.
Just IMHO
