Hey! The Market's Up Nicely This Morning! Well, not really....

Hey, the market's up 90 as I type! Uh, well, actually, it's not; the Dow (with its 30 constituents) is up 90.. 

The Nasdaq Composite (with its 3000 constituents) is down 80...

The S&P 500 (with its 505 constituents) is dead even (as I type)...



Hence -- headlines notwithstanding -- the Dow is not the metric you should be watching every day. 

Of course -- assuming you're an investor (as opposed to a trader) -- you're not the least bit concerned with daily fluctuations anyway, right?
