US stock closing: U.S. stocks drifted in light volume on Wednesday, ending little changed, as investors remained cautious after the S&P 500 index briefly hit its highest intraday level since November 2007.
The S&P 500 was buoyed by General Electric after cable company Comcast Corp said it will buy from GE the the part of NBCUniversal it didn't already own for $16.7 billion.
Comcast's stock hit the highest since 1999 before closing up 3 percent at $40.13 and GE gained 3.6 percent to $23.39.
The S&P 500 is up 6.6 percent so far this year, partly due to stronger-than-expected corporate earnings and a better economic outlook. The Dow industrials is about 1 percent away from an all-time intraday high, reached in October 2007.
Volume has been weak in recent days with the S&P moving sideways around 1,520. The index is about 3 percent away from closing at a record high.
A scarcity of sellers after a consistent string of gains is a positive sign and shows the uptrend is intact, King Lip, chief investment officer at Baker Avenue Asset Management in San Francisco, said.
"Last year we had double-digit returns in the first quarter. It's fairly possible we can move higher from here," he said.
The Dow Jones industrial average fell 35.79 points or 0.26 percent, to 13,982.91, the S&P 500 gained 0.9 point or 0.06 percent, to 1,520.33 and the Nasdaq Composite added 10.38 points or 0.33 percent, to 3,196.88.
The S&P gained 12 percent in the first three months of 2012.
