Strength in energy lifted U.S. stocks on Tuesday as investors concentrated on adding to winning positions as the quarter winds down, but uncertainty kept trading volume light.
About 6.2 billion shares traded in composite volume on the New York Stock Exchange, NYSE Amex and Nasdaq, the second-weakest of 2011 and far below last year's estimated daily average of 8.47 billion.
Conviction has been weak as investors assess the effect of Japan's earthquake and turmoil in the Middle East on corporate results.
I don't think a lot of people know what to do. They hear about how bullish it is to reconstruct Japan but until the disaster is quantified, they are not going to do anything, said Shawn Hackett, president of Hackett Advisors in Boynton Beach, Florida.

Oil services stocks rose for a fifth session as investors continued to add to a sector sitting at its highest since August 2008. The PHLX oil services sector index <.OSX> rose 1.9 percent.
Until the oil market cracks, momentum traders are buying the oil services stocks because that's what's working, Hackett said. Until crude breaks the $100 level back down, you're going to continue to see a strong bid on oil service stocks.
All 10 of the S&P 500's major sectors rose, with energy <.GSPE> up 1 percent.

Oil prices have traded near multi-month highs recently, underpinned by weeks of unrest in Libya and in oil-exporting countries in the Middle East. U.S. crude settled up 0.8 percent near $105 per barrel.
Volume was also weakened ahead of data on the labor front, including the ADP private-sector employment report on Wednesday and the U.S. government's key non-farm payrolls report on Friday.
The Dow Jones industrial average <.DJI> gained 81.13 points, or 0.67 percent, to 12,279.01. The Standard & Poor's 500 <.SPX> rose 9.25 points, or 0.71 percent, to 1,319.44. The Nasdaq Composite <.IXIC> added 26.21 points, or 0.96 percent, to 2,756.89.
The S&P 500 index has risen 4.9 percent in the first three months of the year, which would be its seventh positive quarter in the last eight.

Investors shrugged off economic data that showed U.S. consumer confidence fell in March as households worried about inflation, while home prices dropped for the seventh straight month in January.
