Oil inventories failed to markedly turn the tide despite more and more public commentary (and perhaps realization) that Libya and unrest elsewhere that is currently on the table may have gone too far in oil. Still, the fear is what lies ahead tomorrow rather than what is happening today. PIMCO's Bill Gross has exited US Treasury bonds from the PIMCO Total Return Fund as well. The markets fought between being up and down on the two-year anniversary of the start of the end of the bear market.

S&P 500 1,320.03 -1.79 (-0.14%)

Some M&A was a help, but investors used today and will likely use tomorrow to determine how they want to be positioned as earnings season kicks off.

Mosaic (MOS), an expert in agricultural fertilizers that counts Potash Corporation of Saskatchewan, Inc. (POT) as a related stock, reported fiscal first-quarter numbers Monday after the bell, but the market wasn't too pleased by them. Although net profit increased, expectations were not met. We've seen this sort of situation before; it can be painful for shareholders, but that's just the way Wall Street operates.

Take a look at the press release. Earnings per share jumped from 23 cents in last year's Q1 to 67 cents this time around. In addition, operational cash flow increased more than three times to $556.2 million.

General Mills (GIS) option was active on call volume of 88K contracts, compared to put volume of 8K contracts.

Stocks were indicated weak all morning after a miserable durable goods figure for July showed a large drop in many segments and after new housing sales were about as equally poor as yesterday's existing home sales. Nouriel Roubini even went as far as to call the double-dip recession being above a 40% chance now. Many stocks rallied after being lower all day, including many counter-intuitive sectors. Most likely that was a result of bottom fishing or bargain hunting. No more, no less.

Despite a positive open after much selling last week, the markets could not hang on to gains. The Chicago Midwest manufacturing data was not as negative as the Philly Fed from last week. It was another strong mergers and acquisitions day. Still, investors sold stocks on another dog day of August. The end of day trading showed that sellers still had a bit more power than buyers. Here are today's unofficial closing bell levels:

Dow Jones 10,174.41 -39.21 (-0.38%)
S&P 500 1,067.36 -4.33 (-0.40%)
