Sure it does. GDP growth in the US will generally be between what say +/-5%. It would be exceedingly rare for it to be outside of that range.
So being off by 3% is a pretty shitty estimate when your range of possible values is so small.
GDP revised down significantly. Dow up 43 points.
How exactly do you make money trying to guess what irrational people will do?
Because over longer periods the market reflects underlying economic trends. If the market is currently mispricing itself due to belief in reports that you believe to be useless, that's obviously an opportunity for arbitrage.
So again, when will you mint your first million using your amazing knowledge of economics?
Dumbass.
