Now to my thoughts on the DJI. I don't think it will continue to drop that much further, but I do think panic will drive it down a bit more. I don't see this as a bubble, it didn't go up because of overconfidence (but it went as high as it because so), it went up because of successful reports, tax cuts, increase in jobs, among other things. For this reason, I don't think it will fall very far, as there is real value (as opposed to Bitcoin for example).
Let this be a lesson to those traders like myself who have only ever traded in the Trump economy; it's not invisible.
