Shares in other big tech companies, including Amazon and Facebook, also fell than 1 percent or more. Of the 10 sectors in the S&P 500, technology companies lost the most.
The Standard & Poor's 500 slipped 1.56 points, a fraction of a percent, to end at 2,000.72.
The Dow Jones industrial average rose 10.72 points, or 0.1 percent, to 17,078.28. The Nasdaq composite, which is dominated by large tech companies, sank 25.62 points, or 0.6 percent, to 4,572.57.
Markets have barely moved this week even with news that, in other times, might cause investors to cheer.
Any good news has to be unusually good to push the S&P 500 past 2,000 and further into record territory, said Uri Landesman, president of Platinum Partners, an investment fund in New York.
"Above 2,000, discretion is the better part of valor," Landesman said. "Most people are kind of reluctant to jump in right now."
Another encouraging report on the U.S. economy came out Wednesday. The Commerce Department said that orders for U.S. factory goods shot up 10 percent in July, the biggest one-month jump on records going back to 1992. That followed strong figures for manufacturing activity and construction spending on Tuesday.
"Everything right now is pointing to greater market strength," said Jonathan Golub, chief U.S. market strategist at RBC Capital Markets. "What usually stops bull markets? It's almost always a recession." And there are no signs of a recession on the horizon, he said.
In Europe, markets surged following reports that Russian President Vladimir Putin and his Ukrainian counterpart had agreed to the broad terms of a peace plan to stop the fighting in eastern Ukraine. Ukraine and Western countries say Russia has armed insurgents in eastern Ukraine. Moscow denies it.
Germany's DAX climbed 1.3 percent. The CAC-40 in France picked up 1 percent. Russia's benchmark MICEX soared 3.5 percent.
Craig Erlam, market analyst at Alpari, said the reports of a cease-fire were "welcomed with open arms by the markets."
The hope, he said, must be that economic sanctions on Russia would soon be lifted, which could help the European economy reclaim lost ground.
"We can't forget that the effects of the crisis have been felt in many countries beyond those directly involved," said Erlam.
The crisis in Ukraine has played a role in hampering the European economic recovery this year. In its monthly survey of the 18-country eurozone, financial information company Markit pointed to the conflict as a culprit behind a sharp fall in its gauge of business activity. Some economists expect the European Central Bank to announce new measures on Thursday to help pull the region out of a rut.
Back in the U.S., Delta Air Lines tumbled 5 percent, the steepest drop of any company in the S&P 500. The airline cut estimates for a measure of revenue, blaming "events in Russia, the Middle East and Africa," an apparent reference to fighting in eastern Ukraine, war in Syria, and an Ebola outbreak in West Africa. Shares in Delta dropped $2.11 to $38.82.
