U.S. stocks closed modestly higher Wednesday as investors welcomed improved reports on the U.S economy, but gains were tempered by concerns about growth in Europe and Asia.

The Dow Jones industrial average rose 0.1%, while the S&P 500 added 0.3%. The Nasdaq gained 0.5%.

After a strong run in the third quarter, investors are now looking for the next catalyst to drive stock prices, said Dan Greenhaus, chief strategist at BTIG. "You need to see a sustained pick-up in economic data and more positive news out of Europe," he said.

The modest gains Wednesday came after payroll processor ADP said the nation gained 162,000 private sector jobs in September. The report is considered a prelude to the government's closely watched monthly jobs data, which is due out this Friday. Investors are hoping to see a rebound in the labor market after last month's grim report.

An index of activity in the service sector of the economy rose for the 33rd month in a row, according to the Institute for Supply Management. In addition, the Mortgage Bankers Association's index, which measures mortgage applications, rose 16.6% for the week ended Sept. 28, up from the prior week's 2.8% increase.

Meanwhile, investors remain focused on Europe, specifically Spain, where there's mounting pressure for the nation to formally request a bailout. Late Tuesday, Spanish Prime Minister Mariano Rajoy said a bailout request was not imminent.
