NEW YORK (AP) -- Stocks surged to all-time highs Friday when a surprisingly good jobs report finally gave investors a clear sign of U.S. economic strength after weeks of conflicting signals.
The market jumped from the opening bell, traders donned party hats, and a wave of buying helped the Standard and Poor's 500 index close above 1,600 for the first time. The Dow Jones industrial average briefly rose above 15,000, a milestone.
"There's euphoria today," said Stephen Carl, the head equity trader at The Williams Capital Group. "That's what you'd have to call it."
On the floor of the New York Stock Exchange, brokers sported baseball caps emblazoned with "Dow 15,000."
Investors are hoping it's more than just a one-day celebration. Jobs are key to keeping stocks climbing. Big U.S.companies are making record profits, but much of that lately has come from cutting costs, not boosting sales. More jobs, and more consumer spending, would help.
The April jobs report was a good start. U.S. employers added 165,000 workers last month and many more in February and March than previously estimated. The unemployment rate fell to the lowest level in four years, 7.5 percent.
The Dow rose 142.38 points to close at a record 14,973.96, up 1 percent. The S&P 500 index climbed 16.83 points, or 1 percent, to 1,614.42, also a record.
"We're breaking through psychological barriers and that will continue to bring investors off the sidelines," said Darrell Cronk, regional chief investment officer for Wells Fargo Private Bank. He called the jobs news "wonderful."
Cronk, like many others on Wall Street, has been watching individual investors for signs they may finally have shed their fear of stocks. A surge in buying from them would help push stocks higher. But individuals late last month pulled more money out of stock funds than they put in, a reversal from the trend earlier this year, according to the Investment Company Institute.
They've had reasons to pull back lately.
First came news of falling retail sales in March, then a series of weak manufacturing reports and signs of an economic slowdown in China.
Other reports, including two out Friday, have pointed to a slowdown. Factory orders sank in March and a gauge of growth in the service sector fell short of estimates.
First-quarter earnings have been mixed, too. Though they've come in higher than expected, many companies have reported little or no revenue growth, which has spooked investors.
Investors have also been concerned that higher Social Security payroll taxes and sweeping government spending cuts that took effect earlier this year will slow U.S. economic growth, and pinch corporate profits.
Friday's jobs numbers suggested the private sector might be strong enough to overcome those obstacles.
In its report, the government revised its previous estimate of job gains up to 332,000 in February and 138,000 in March. The economy has created an average of 208,000 jobs a month from November through April -- above the 138,000 added in the previous six months.
"Jobs are key," said Randall Warren, chief investment officer of Warren Financial Service in Exton, Pa.
