A rise in tech stocks led the U.S. indices to a higher close Monday, offsetting more credit worries for insurers and finance companies.


Nasdaq Composite

opened lower but bounced back to gain 15.21 points, or 0.66%, to 2320.06. The advance came on the back of semiconductor names, including

After falling more than 100 points earlier, the

Dow Jones Industrial Average

turned higher and climbed 57.88 points, or 0.48%, to 12,240.01. The blue-chip average shook off an 11.7% drop in

S&P 500

also overcame a weak start and added 7.84 points, or 0.59%, at 1339.13.

Financial subsector indices were pressured by AIG's loss. The NYSE Financial Sector Index slid 1.4%, and the Nasdaq Financial 100 Index was down 0.9%. On the winning side, the Philadelphia Semiconductor Sector Index rose 1.6%.

"The negative information from AIG doesn't seem to have really spooked anyone," said Edgar Peters, chief investment officer with Pan Agora. "Hopefully this means that news of fresh subprime issues won't hurt the rest of the market."

A rise in oil futures benefited related stocks. The Philadelphia Oil Service Sector Index jumped 3.4%, thanks to sharp gains in

Crude oil added $1.82 to finish at $93.59 a barrel on threats from Venezuelan President Hugo Chavez that he would considering cutting off supplies to the U.S. Gold futures, meanwhile, gained $4.40 to $926.70 an ounce. The dollar was weaker against the euro and the yen.

Breadth was slightly positive to start the week. About 3.44 billion shares changed hands on the

New York Stock Exchange

, with advancers beating decliners by a 17-to-16 margin. Volume on the Nasdaq reached 2.04 billion shares as winners edged losers 15 to 14.

"Technically, I believe the market has entered the base-building phase," said Marc Pado, U.S. market strategist with Cantor Fitzgerald. "Volume is lighter and breadth more subdued."

Paul Nolte, director of investments with Hinsdale Associates, said "sentiment remains fairly low and expectations about the future also remain dour. The short-term rally that broke the early-year selling last week quickly gave way to renewed selling this week. Revisiting the January lows, the market is on the precipice. It could turn higher, putting in at least a short-term bottom, or fall through the recently established bottom to push to new lows."

Chairman Ben Bernanke will appear Thursday before the U.S. Senate committee on banking and housing to testify on the economy and financial markets.
