Euro breaks out, stocks blasted

The S&P 500 is now down 30 points. And that's after opening 13 points higher an hour ago.

The turnaround in sentiment today has been astounding.

As I pointed out yesterday, last week's high in the S&P 500 matched the 50% retracement of the Jan decline. That was a bearish signal.

Now, the index is flirting with last week's low print. Look for more stops if it gives way.

The market moves have been like a bolt of lightening today.
