With violence in Israel and Lebanon continuing into a sixth day and no resolution in sight, the markets remained wary despite a sharp drop in oil prices. A barrel of light crude settled at $75.30, down $1.73, on the New York Mercantile Exchange.

"Unfortunately, right now this conflict in the Middle East is the elephant in the room, and nothing's going to happen until there's a little more clarity there," said Jack Ablin, chief investment officer at Harris Private Bank. "This is probably a market best viewed from the sidelines."

The U.S. economy continued to show strength, with industrial production rising 0.8 percent in June, according to the Federal Reserve, far better than the 0.4 percent economists expected. That encouraged investors who had feared the economy would have trouble withstanding high energy prices and higher interest rates.

The Dow Jones industrial average rose 8.01, or 0.07 percent, to 10,747.36. The Dow slid 3.17 percent last week.

Broader stock indicators were narrowly mixed. The Standard & Poor's 500 index lost 1.71, or 0.14 percent, to 1,234.49, and the Nasdaq composite index climbed 0.37, or 0.02 percent, to 2,037.72.

While the Fed's overall production data was strong, a report by the New York Federal Reserve showed slower-than-expected manufacturing growth in New York state. The Empire State Index fell to 15.6 in July from 29 in June. Economists expected the index to fall to 20.

The conflicting manufacturing reports did little for the bond market, with the yield on the benchmark 10-year Treasury note steady at 5.07 percent from late Friday. The dollar made gains against most major currencies, and gold prices also climbed.

The mix of news and mediocre earnings led to lethargic trading, especially with the consumer price index and producer price index — two key measures of inflation — due later in the week along with congressional testimony from Fed Chairman Ben Bernanke Wednesday and a slew of major earnings reports.

"There's not much news out today that's really going to push the markets either way, so you're seeing this choppy tape right now," said equity trader Brian Williamson of the Boston Company Asset Management. "You got 80 percent of the S&P 500 reporting over the next four weeks, so the scale's not ready to be tipped either way yet."

Dow industrial Citigroup was another in a line of mildly disappointing earnings reports that have stoked investors' concerns over stocks in recent weeks. Citigroup just missed Wall Street's profit forecasts by a penny per share, and its stock fell $1.18 to $46.40.

The news countered a strong sales report from fellow Dow component McDonald's Inc., which rose $1.68 to $34.72 after posting a 5.9 percent increase in June sales at stores open at least a year. The fast-food chain credited strong overseas sales and increasing breakfast demand for the gains.

Mattel Inc. posted a quarterly gain after a year-ago loss, with sales boosted from tie-in products from the "Superman Returns" and "Cars" films even as its core Barbie and Hot Wheels lines slipped. Mattel jumped $1.72, or 11 percent, to $17.60.

Declining issues outnumbered advancers by nearly 9 to 7 on the New York Stock Exchange, where preliminary consolidated volume came to 2.24 billion shares, compared with 2.57 billion traded Friday.

The Russell 2000 index of smaller companies was down 3.55, or 0.52 percent, at 677.69.

Overseas, concerns over the Middle East and North Korea's nuclear program sent Japan's Nikkei stock average tumbling 1.67 percent. In Europe, Britain's FTSE 100 closed down 0.12 percent,France's CAC-40 lost 0.64 percent for the session, and Germany's DAX index fell 0.1 percent.
