Heres how i see things right now. Trump has used techniques "tax cuts" to prop up this aging bull market. These things should have been used during a time of hardship not used during times of prosperity. So who gallops in when things turn down, yes we all know the Federal Reserve will come up with more QE.
However if Trump looses the House and Dems start to gain traction....Trump will toss up his hands and say....I told you so....if Dems got power back they would crash the markets, and he may even pile on to tank it lower knowing his time is up.
If Trump keeps both houses, he will continue to lean and jaw bone the Fed. Im really hoping for a major market correction, to wring the excesses out.
