Its the impeachment that would tank the market. The killer of this bull market will be people like Mueller and Lindsey Graham. if impeachment proceedings go forward against Trump the market will see the Panic Cycle hit on a yearly basis. This is actually bad for the entire world as Trumps tax plan has forced other countries to admit that their tax structures are not competitive either. Trump won because people had enough of career politicians. The Dow has reached a turning point. a November high has seen January's numbers go higher. Now the Failure of February to make new highs will see a March low. The support for correction is at the 25637 level on a weekly closing basis.
The Dow is not a measure of how everyday middle and lower class Americans are doing, it just means that rich people and corporations are doing well while everyone else falls behind. I'm sure you think daddy Trump is super awesome but the truth is that he doesn't give a shit about you.
