Investors watch confidence measures for signs of whether consumers might start shopping more or making bigger purchases such as cars and homes. Spending by consumers makes up more than two-thirds of U.S. economic activity.
Jim King, chief investment officer at National Penn Investors Trust Co., said the improvement in consumer confidence surprised investors. With unemployment still high and expected to go higher, many market watchers thought the mood on Main Street would remain gloomy.
"The consumer confidence figure is one that no one really pinned a lot of hopes on as going higher," he said.

Investors have been questioning whether the stock market's massive two-month rally can be sustained given the continuing weakness in the global economy. The Dow is still up 26.4 percent from its 12-year low hit on March 9. Even with those gains, the Dow is still down 41.6 percent from its peak in October 2007.
A month ago, stocks reversed a slide after consumer confidence showed improvement. Investors have since been looking for more signs that the economy is stabilizing. The initial enthusiasm that powered the market's rally since March stalled as investors wondered whether they had been too quick to buy stocks given the problems the economy still faces in areas like housing, unemployment and souring loans.
The jolt from consumer confidence is helping the stock market but some of the improvement is also tied to the stock rally itself.
Bill Stone, chief investment strategist at PNC Wealth Management, said some money managers are forced to step in when the news is good just because they are afraid of being left behind and showing poor returns.
"You've still got a lot of people left that really don't want to like this market but may eventually be forced," he said.
Stone is encouraged by the skepticism because it could help hold the rally in check.
After mixed economic data over the last couple weeks, as well as a huge number of stock offerings by banks, the market is likely to stay volatile in the coming weeks, said Steven Goldman, chief market strategist at Weeden & Co. "The market's had a pretty huge gain here," he said.
