NEW YORK, Jan 16 U.S. stocks fell off five-year highs on Wednesday as concerns about global economic growth offset strong bank results and shares of Boeing weighed on the Dow after two Japanese airlines grounded their Dreamliner fleets.
Goldman Sachs shares hit an 18-month high as its earnings nearly tripled on increased revenue from dealmaking and lower compensation expenses, while JPMorgan Chase said fourth-quarter net income jumped 53 percent and earnings for 2012 set a record.
JPMorgan shares were last down 0.8 percent at $46 and Goldman added 2 percent to $138.26.
Concern about global economic growth was weighing on the markets, said Peter Jankovskis, co-chief investment officer at OakBrook Investments in Lisle, Illinois.
A slow economic recovery in developed nations is holding back the global economy, the World Bank said on Tuesday, as it sharply scaled back its forecast for world growth in 2013 to 2.4 percent from an earlier forecast of 3.0 percent.
Shares of Dow component Boeing fell 3.5 percent to $74.25 on concerns about the safety of its new Dreamliner passenger jets. Japan's two leading airlines grounded their fleets of 787s after an emergency landing, adding to safety concerns triggered by a ream of recent incidents.
"It's certainly going to pull averages down, given Boeing's large market cap, but I don't see it as having broader market implications," Jankovskis said.
The Dow Jones industrial average fell 61.79 points or 0.46 percent, to 13,473.1, the S&P 500 lost 4.39 points or 0.3 percent, to 1,467.95 and the Nasdaq Composite dropped 2.72 points or 0.09 percent, to 3,108.06.
Losses on Nasdaq were limited by gains in Apple shares, which were up 2 percent at $495.75.
Talks to take Dell Inc private were at an advanced stage, with at least four major banks lined up to provide financing, two sources with knowledge of the matter told Reuters. Shares fell 3.6 percent to $12.69 after jumping more than 21 percent over the past two sessions.
U.S. consumer prices were flat in December, pointing to muted inflation pressures that should give the Federal Reserve room to prop up the economy by staying on its ultra-easy monetary policy path.
