May 13 (Reuters) - Wall Street's major indexes gave up early gains to end Wednesday's session little changed as some investors stood on the sidelines waiting for the next round of economic data at the tail end of earnings season.

U.S. retail sales were unchanged in April as households cut back on purchases of cars and other big-ticket items and import prices fell for a 10th straight month in April and business inventories barely rose in March.

The data suggested to some investors that the U.S. economy was struggling to rebound strongly enough for the Federal Reserve to raise interest rates before September.

"You're now heading from an earnings-centric market to a macro-focused market," said Andrew Frankel, co-president of Stuart Frankel & Co in New York. "People seem to be in watch mode as they get an understanding of what's next."

In particular, investors are waiting for inflation numbers and the next jobs report in coming weeks, said Michael Matousek, head trader at U.S. Global Investors Inc in San Antonio.

However, Brian Fenske, head of sales trading at ITG (Shanghai: 600755.SS - news) in New (KOSDAQ: 160550.KQ - news) York, said he was seeing solid volume of investors adjusting their portfolios after earnings season.

"I'm seeing more healthy activity which is buying, selling and shorting stocks," said Fenske. "I'm seeing a return of conviction."

The S&P's information technology index, was the best performer with a 0.5 percent increase.

The S&P utilities index was the worst performer, with a 1.1 percent drop. Duke Energy weighed most on that sector and AES Corp fell 2.5 percent drop after it priced a secondary share offering.

"It's a gauge of people's perspectives as to what the Fed will do next," said Frankel, adding that utilities are in favor if people think the Fed will stall on interest rate hikes.

The Dow Jones industrial average fell 7.574 points, or 0.04 percent, to 18,060.49, the S&P 500 lost 0.64 points, or 0.03 percent, to 2,098.47 and the Nasdaq Composite added 5.50 points, or 0.11 percent, to 4,981.69.

DuPont shares fell 6.8 percent to $69.33 after it won a proxy fight against Nelson Peltz's Trian Fund Management. The stock was the biggest drag on the Dow Jones industrial average.

Macy's fell 2.4 percent to $63.73, while Ralph Lauren fell 3 percent to $129.18 after they reported results.

Pall Corp rose 4.4 percent to $123.89 after Danaher said it would buy the company in a $13.8 billion deal. Danaher (Xetra: 866197 - news) was up 1.6 percent at $87.35.

Shares (Frankfurt: DI6.F - news) of pipeline company Williams Partners LP jumped 22.7 percent to $58.16 after Williams Cos said it would buy its affiliate for about $13.8 billion.

Advancing issues outnumbered declining ones on the NYSE by 1,695 to 1,369, for a 1.24-to-1 ratio; on the Nasdaq, 1,369 issues rose and 1,345 fell for a 1.02-to-1 ratio favoring advancers.

The S&P 500 posted 13 new 52-week highs and 4 new lows; the Nasdaq Composite recorded 64 new highs and 34 new lows.

About 6.1 billion shares changed hands on U.S. exchanges, compared with the 6.6 billion average for the last five sessions, according to data from BATS Global Markets. (Editing by Saumyadeb Chakrabarty and Nick Zieminski)
