It went into the ground before the first cases were even confirmed in the US.
When the supply chains for most of these American mega corps are in question, the economy starts falling. And you legitimately think this has anything to do with Trump, much less anything in the US at all?
If you want to see a crash that'll make the 2008 GFC look like a gold rush, just wait until a nearly dead senile old man is elected.
Live by the sword, die by the sword. An effective leader doesn't tell everyone he's a genius...stable genius (is that a horse trainer?)....and pound his chest saying how well he's done for the economy....without recognizing that he'll get blamed if things go south.
The "value" of securities in the market assume that the market is "orderly". Huge spikes say that the market isn't orderly and that the real, underlying values are likely overstated. I think most people know this and don't really care as long as they can trade in and out in an orderly market. To say that the markets lost $7 trillion in "value" really isn't true. It lost phantom value.
