NEW YORK, Nov 19 (Reuters) - Wall Street bounced on Monday as investors were heartened by signs of progress in talks to resolve the fiscal crunch and data that showed the recovery in the housing sector was gaining strength.
The major indexes climbed more than 1 percent after tumbling in recent weeks on nervousness over when and if Washington will come to an agreement to avoid the series of tax and spending changes that will start to come into effect in the new year.
Over the weekend, leading Democratic and Republican lawmakers expressed confidence that they could reach a deal to avert the "fiscal cliff", even as they laid down markers on raising taxes and spending cuts that may make any agreement more difficult.
"What you're seeing today is an oversold bounce in the market," said Michael Sheldon, chief market strategist at RDM Financial in Westport, Connecticut.
"This could last for a few more days, but ultimately we'll need to see what type of legislation or forward progress comes out of Washington."
Stronger-than-expected earnings from Lowe's and Tyson Foods, as well as encouraging housing data also contributed to the market's advance.
U.S. home resales unexpectedly rose in October, while separate data showed homebuilder sentiment rose to its highest level in over six years in November.
The PHLX Housing Index rose 1.7 percent.
The Dow Jones industrial average gained 163.07 points, or 1.30 percent, to 12,751.38. The Standard & Poor's 500 Index rose 21.52 points, or 1.58 percent, to 1,381.40. The Nasdaq Composite Index climbed 46.51 points, or 1.63 percent, to 2,899.64.
The S&P 500 was approaching its 200-day moving average around 1,382. Rising back above the key technical level could provide additional support for the index.
Shares of Lowe's Cos Inc, the world's No. 2 home improvement chain, jumped 6.3 percent to $33.99 after the company reported higher-than-expected quarterly profit and raised its full-year sales forecast.
Tyson Foods Inc likewise beat expectations and gave an upbeat forecast, sending its stock up 8.5 percent at $18.32.
Intel shares erased earlier losses to trade higher after the company said its chief executive will retire in May. Intel was up 0.9 percent at $20.37.
