Investors were initially heartened after a government report showed that U.S. retail sales rose for the first time in four months in July, a sign that the economy may have started strengthening in the middle of the summer.
"We saw strength in retail sales across the board last month, and that indicates that the underlying trend we saw in consumer spending last quarter may actually be stronger," said Michael Sheldon, chief market strategist at RDM Financial Group.
That bodes well for the broader economy since consumer spending historically accounts for two-thirds of U.S. economic activity, he said.
The positive data comes just before the key back-to-school shopping season for retailers.
Meanwhile, France and Germany released second-quarter gross domestic product figures that beat analysts' expectations, but preliminary data showed the eurozone economy on the whole continued to shrink.
Eurozone GDP shrank by 0.2% between April and June compared to the previous quarter and 0.4% year-over-year, according to flash estimates published by Eurostat, the statistical office of the European Union. In the first quarter of 2012, GDP was unchanged.
"Today's GDP data reinforces the fact that there are two different parts of Europe from an economic perspective," said Sheldon. "Economic activity in the north continues to muddle along at a neutral to slightly positive rate, while the southern part of Europe remains mired in a recession."
With more signs of a persistent slowdown, investors are hopeful that the figures will continue to build a case for central banks to step in with further stimulus measures.
Still, trading volume remains very low, and many investors aren't placing any significant bets as the market slips into the usual summer doldrums. That could make it tougher to gauge if the recent rally is for real until September.
