This final note today, which can properly be filed under the 'What the heck does Wall Street know, anyway?' label.

Apple reported fourth quarter profits after the closing bell today. A tidy $6.6 billion straight to the bottom line.

Not, though, apparently enough for Wall Street, which sent Apple shares down 8 percent in after-hours trading. That's the same Apple that sold 4 million new iPhones this past weekend.

And yes, I know this past weekend doesn't in last quarter's profits, but c'mon. The things are like printing money.
