This is nothing new. Since at least the time when I was a kid and first watched a news program, business reporters have everyday said one or the other of the following:

said “the market was up x points on noticeable positive event y”

_or _

“the market was down w points on noticeable troubling event z.”

Fact is, no one can say for sure why the market went up or down that day unless they say, for example ” the market was up because more investors found its offerings attractive than unattractive.” So if you are not a moron, you simply dismiss the suggested correlation as at best a gross oversimplification. It’s boilerplate, formulaic, evergreen nonsense. So what?
