The Trump love on these threads never ceases to amaze me. It's hard to even begin to make sense of it.
First and foremost, the Dow is not the economy. The economy is actually going along fairly well, and has been for quite some time now under both Obama, and then Trump. This is a non-partisan fact. The reason I can say this is, the executive branch has very little effect on the overall health of the economy, as proven by statistical analyses, but what effect it does have can be quite visible, so a lot of people "think" the president creates or destroys an economy. It is more a set of policies that have a direct effect over the long term. Anyway, below are the issues going on right now.
The Dow collapsing like it has been over the last two weeks has a lot to do with the following factors:
1.) Rising interest rates
2.) Uncertainty due to the trade wars, immigration policies, domestic policies, resignations, criminal investigations, and general wtf-ery of the current executive branch.
3.) Student loan debt
4.) Market corrections (we've been going up for so long, usually around this time the market "corrects" and things drop a bit).
5.) Supply chain disruptions for tech stocks (related to the China trade wars)
Under more stable circumstances, this kind of correction to a Bear market for a little while would feel more natural. Under these circumstances, however, it adds to the feeling of uncertainty, which compounds the problem from a psychological perspective.
