NEW YORK (MarketWatch) -- U.S. stocks were little changed on Monday afternoon, with the S&P 500 pausing from its record climb, as Wall Street considered earnings and Tuesday's delayed release of the nonfarm-payrolls report for September.

"This has been a year of significant multiple expansion," said Paul Karos, a senior portfolio manager for Whitebox Mutual Funds, of the price-earnings ratio of U.S. equities. But since that expansion has not coincided with a broad-based earnings revision upward, "it would not be surprising to see equity markets take a breather," given the market's more than 20% rise so far this year, he said.

"We can continue to grind higher, but it's a grind, the next sustainable leg would probably need to come from upwardly revised earnings estimates, that could be hard to come by," Karos added.

Wavering between small gains and losses, the Dow Jones Industrial Average (DJI) was lately down 4.76 points at 15,394.89.

McDonald's Corp. (MCD) fell 0.7% after the fast-food chain reported sales below expectations. Another Dow component, AT&T Inc., (T) climbed 1.2% after the telecommunication company agreed to sell or lease 9,700 wireless towers.

J.P. Morgan Chase & Co. (JPM) was little changed after the bank reportedly agreed to pay $13 billion to halt U.S. civil investigations into its mortgage-bond sales.

The S&P 500 index (SPX) held steady at 1,744.51, with health care losing the most ground and telecommunications faring best among its 10 sectors.

Gannett Co. Inc. (GCI) shares lost 4.6% after the newspaper chain reported a 4% decline in quarterly revenue. Hasbro Inc. (HAS) gained 5.6% after the toy seller reported third-quarter results that beat Wall Street's expectations.

The Nasdaq Composite (RIXF) added 8.64 points, or 0.2%, to 3,922.88.

Decliners moved just ahead of advancers on the New York Stock Exchange, where 317 million shares traded as of 1:44 p.m. Eastern time. Composite volume neared 1.8 billion shares.

Equities improved after the National Association of Realtors reported existing U.S. home sales fell 1.9% in September due to rising prices and mortgage rates.

Gold futures (GCZ3) rose $1.20 or 0.1%, to $1,315.80 an ounce, and crude futures (CLX3) lost $1.58, or 1.6%, to $99.23 a barrel on the New York Mercantile Exchange.

The dollar(DXY) gained against the currencies of major U.S. trading partners, including the euro (EURUSD) and the yen (USDJPY).

The yield on the 10-year Treasury note (10_YEAR) used in figuring mortgage rates and other consumer loans rose 3 basis points to 2.615%.

"Both the economy and earnings appeared to have had good momentum going into the fourth quarter. However, analysts will still need to assess how much the (government) shutdown hurt the economy," noted David Kelly, chief global strategist at J.P. Morgan Funds, in emailed commentary.

The global economy is "still on the mend in the face of the easiest monetary policy ever implemented by developed-nation central banks. As the economy improves and earnings rise, this aid will gradually be reduced, boosting interest rates. Despite recent stock-market gains, such an environment still supports the idea of an overweight to equities relative to fixed income around the world," wrote J.P. Morgan Funds' Kelly.
