NEW YORK -- Stocks rose Monday, helped by signs that Washington was moving closer to a deal that would avert a default by the U.S. government.
The stock market started the session broadly lower after negotiations between the White House and House Republicans broke down over the weekend. However, stocks erased those losses in early afternoon trading following news that President Barack Obama would meet with Congressional leaders.

The Republican Senate leader, Mitch McConnell, seconded Reid's view, saying there had been "a couple of very useful discussions."

Investors continue to express hope that a deal can be reached before the debt crisis causes any lasting damage. In the last few years, political deals over major budget disputes have gone down to the last minute.

The U.S. government remains partially shut down because House Republicans want to attach conditions to a budget bill that would scale back the country's new health care law. President Barack Obama is insisting that the government be reopened without strings attached. The partial shutdown is entering its third week.

"We're basically trading on the news at this point," Lynch said.
