NEW YORK - Optimism that a budget deal will be reached in Washington sent stocks modestly higher Thursday. A pair of economic reports also brightened the mood.

The Dow Jones industrial average rose 36.71 points to close at 13,021.82.

The stock market took a brief turn lower when House Speaker John Boehner said little progress was being made in budget talks in Washington. The Dow was up as much as 77 points in morning trading, turned negative as Boehner made his remarks at 10:30 a.m. CST, then slowly recovered in the afternoon.

Investors were encouraged by several positive economic reports, including a higher estimate of third-quarter U.S. economic growth, an increase in home sales and a drop in claims for unemployment benefits.

After a meeting with Treasury Secretary Tim Geithner, Boehner told reporters that Democrats still haven't said which cuts they would accept to government benefit programs, suggesting a final budget deal remains a long way off. Republicans have said that they are open to increasing tax revenue as part of an agreement but only if they're accompanied by significant cuts to spending.

Investors have been closely watching the talks between the White House and Congress over the "fiscal cliff," a reference to sharp government spending cuts and tax increases scheduled to start Jan. 1 unless a deal is reached to cut the budget deficit.

"It's a headline-watching market with this fiscal cliff," said David Brown, chief market strategist for research firm Sabrient Systems.

In other trading, the Standard & Poor's 500 rose 6.02 points to 1,415.95. The Nasdaq composite index gained 20.25 points to 3,012.03.
