You could be correct. And time will tell whether such Trump’s erratic behavior creates lasting damage.
But for the time being, I think the most useful explanation is simply that the market was looking for an excuse to make a correction.
I bought some US Steel just after the opening bell this morning.
I expect it will be back up in the near future.
The difference between me and professional traders is that their entire careers hang in the balance with every decision.
Me? Not so much.
On top of that, I have watched Trump for a long time and have a very clear understanding of how he operates.
Trump's style looks chaotic, but that because he doesn't show his opponent (or us) his negotiating strategy.
Trump is a cool customer.
