(New York) CNNMoney — By Ben Rooney
NEW YORK (CNNMoney) -- The stock market continued its march higher for a fourth week as investors focused on signs of improvement in the U.S. economy.
The Dow Jones industrial average, S&P 500 and Nasdaq all ended higher Friday, with the Dow and S&P 500 finishing at record levels. For the week, the S&P 500 added 2%, the Dow rose 1.5% and the Nasdaq advanced 1.7%.
Friday's gains came after a measure of consumer sentiment rose to its highest level in nearly six years. Separately, a report on leading economic indicators bounced back in April.
U.S. stocks took a step back Thursday amid a raft of mixed economic reports and as some Federal Reserve officials called for an end to monetary stimulus this year.
"The market is very sensitive to comments about the Fed pulling back," said Quincy Krosby, market strategist with Prudential Financial. But Friday's economic reports "helped assuage fears that the economy and consumer were going deeper into a soft patch."
All three indexes have gained around 16% so far this year on a combination of gradually improving economic data and continued support from the Fed.
But the economic outlook may not be as rosy as some would hope, said Bruce McCain, chief investment strategist at Key Private Bank.
"The euphoric reaction in the market is justified to a degree," he said. "But it may overestimate the growth we may see here and overseas."
Meanwhile, gold prices dropped 1.6% to settle firmly below $1,370 an ounce. The precious metal has taken a beating during the past few weeks as investors rotate out of safe-haven assets.
