"Dow down < big number here > points!" heard yesterday.
That report is on The List.
Why? Historically the Dow waggles +/- 1% on any day; specific news will waggle it +/- 2% in a day; an event will move it more in a day.
The Dow moving 400 points right now in a day is a <2% move; noteworthy, yes, but not earth shattering. (Tech stocks had a bad day yesterday; that was the news, not the points number.)
Not understanding that, just shouting the big scary number, puts innumeracy on The List.
