Stock market goes up and down

So every day after the market closes I check to see how the market did. And every day there's a little blurb like this one. "Stocks generally went up" or "Stocks went down" or "Stocks went sideways."

No biggie. But today as I read it what irritated me was the reasons for the decline. How in the hell does anyone proclaim to know why the market went down or why it went up? Unless something major happened (nothing did today), why the hell put that crap in there in the first place? "Consumers were afraid of..." is a bunch of crap.

Just another piece of evidence showing how random the whole market is to begin with on a short-term basis.
