On Monday, the Dow Jones industrials closed above 11,000 for the first time in a year and a half. And last month employers added 162,000 jobs -- the largest job gain in three years.

"There is a huge stockpile of cash on the sidelines earning virtually nothing," said Jack Ablin, chief investment officer at Harris Private Bank in Chicago. "Maybe this can help shake a few people into the market."

Consumer spending is also up for the past five months.

"Consumers are getting more comfortable, which is an essential ingredient for a sustainable recovery. The Federal Reserve should be pleased to see steady spending growth, but will not raise rates until the job picture improves," chief economist at FTN Financial in New York Chris Low told Reuters.

Also, the auto industry received a 37 percent boost in sales last month.

But economists warn there are still problems like bad mortgages in the housing market and interest rates may pick up, making it harder for individuals and small businesses to get credit.
