The stock market was down without much conviction in the early going with the DJIA off 40 to 50 points. But someone must have pulled the plug somewhere as it has been dropping fast from about 2 p.m. and the Dow was down over 180 points as I pecked away at the keyboard.

What the heck changed overall market sentiment so suddenly? Some say it's oil prices drifting higher. That's always a good scapegoat and probably has something to do with it. It might also be a connected issue with the raging conflicts in the middle east and Africa.

There is always the negative sentiment about housing, employment, last night's democratic primaries in Indiana and North Carolina just muddling on. It might also be our current president just muddling on, or it might just be that all of these things just prompted some profit taking after weeks of appreciation.

Maybe it is my pal Warren's negative sentiment about the financial sector and the years of pain that may still need to be worked out of the system. Whatever it is you can be sure that after the market closes the Wall Street pundits will discuss all their presumptions as if they were facts...

UPDATE: The DJIA closed at 12,814.35 down -206.48, or -1.59%
