I think you nailed it, the big drops began around the time of the election, down 7% in a month. I also notice that now we have begun reporting on the stock market and the economy every news cycle for the first time in over a year...hum...why is that you ask? Simple because when the market goes down, it gives the press time to pile on Trump some more.
The dow right now is at 24400 down about 600+ today on top of tuesday’s debacle of 800 down. By historic standards there should be a pop in here to the upside soon, probably around 24000.
Well over 700 points down now (Dow).
Drudge has his screaming headlines up about it, of course. That would seem to have some extra effect.
