Stocks reversed course and rose Monday as crude oil prices headed lower, while a near 6-percent surge in insurer American International Group (AIG) helped the Dow.

The Dow Jones industrial average (search) closed up 16.84 points, or 0.16 percent, at 10,421.14, based on the latest available data. The Standard & Poor's 500 Index (search) closed up 3.20 points, or 0.27 percent, at 1,176.12. The Nasdaq Composite Index (search) closed up 6.26 points, or 0.32 percent, at 1,991.07.

Earlier, the Dow touched a new intraday low for 2005, falling to its lowest level since early November.

But AIG rose after New York Attorney General Eliot Spitzer (search ) said a "civil resolution" was achievable in his probe of the insurer's accounting. AIG gained $2.35 to $53.30.

"The market's very oversold and there are some pretty pessimistic expectations right now," said John Hughes, managing director at Epiphany Equity Research.

"But seasonally we're getting into the spring-time and that typically leads to a rally. What's driving (the market) today is oil -- it started the day higher but has come off. Also the news out of AIG almost did more for the market than oil did."

U.S. crude oil futures seesawed in and out of negative territory on Monday as traders took profits after oil rose to a record high of $58.28 per barrel in overnight trade. NYMEX May crude futures settled $57.01, down 26 cents on the New York Mercantile Exchange (search) after hitting a record high at $58.28 in overnight electronic trade.

"It's hard to say where that line in the sand is, that level for oil prices where the market will seriously sell off," said Scott Wren, equity strategist for A.G. Edwards & Sons. "I do think that if you have sustained levels of $60 to $65, then the market will be very hard pressed to make any move to the upside."

Not even ChevronTexaco's (CVX) move for Unocal, which valued the company at $62 per share, was enough to move the market. Unocal (UCL) tumbled 7.4 percent, or $4.75, to $59.60, due to the relatively low valuation; ChevronTexaco lost 3.9 percent, or $2.33, to $56.98.

A Morgan Stanley spokeswoman called the report a "market rumor."
