As the U.S. stock market struggled Monday in the wake of the prior session's losses, technology remained a bright spot after emerging as the only sector to eke out gains last week.

On Monday, tech shares were among the few issues climbing as the major equity indexes reversed course after morning gains, with consumer-discretionary shares up the most and financials lagging.

After climbing nearly 100 points, the Dow Jones Industrial Average (DJI) was lately off 41.57 points, or 0.4%, at 9,930.61.

"The financial sector is putting the most pressure on the overall market. There are two major concerns: Bank of America (BAC) will most likely have to raise money to pay back TARP, and over the weekend we certainly added to the list and got over the century mark for the number of banks that have gone under the waves," said Art Hogan, chief market strategist at Jefferies & Co.

The S&P 500 (SPX) shed 5.35 points, or 0.5%, to 1,074.25, while the technology-driven Nasdaq Composite Index (RIXF) was the last to give up gains, retreating a dozen points.

As of Friday's close, 62% of S&P 500 component companies reporting their quarterly results had topped analysts' expectations for sales -- and tech's accounted for the best revenues as compared with Wall Street's pre-report outlooks. Overall, sales are still on track to drop about 10%, according to Thomson.

"Tech was the only sector to rise last week and is still the best performer year-to-date with a gain of 49.5%," wrote Ed Yardeni, chief investment strategist of Yardeni Research Inc., in a Monday note.

"Eight of the 10 S&P 500 sectors are confirming the cyclical rebound in forward earnings, with new record highs for consumer staples and health care. Information technology is showing the best come-from-behind performance," said Yardeni.
