U.S. stocks were little changed Friday after a stronger-than-expected reading on inflation in April.

Federal Reserve officials are watching for signs that inflation is picking up as they debate when to raise short-term rates for the first time since June 2006.

The Dow Jones Industrial Average fell 13 points, or 0.1%, to 18273. The S&P 500 slipped 1.4 points, or 0.1%, to 2129 while the Nasdaq Composite rose 5.6 points, or 0.1%, to 5096.

The consumer-price index rose 0.1% in April from a month earlier, the Labor Department said Friday. Excluding the food and energy categories, so-called core prices gained 0.3%, the largest increase since January 2013. Economists surveyed by The Wall Street Journal had expected overall prices to increase 0.1% and core prices to rise 0.2%.

Stocks rose Thursday, propelling the S&P 500 to a record close. The S&P added 0.2% to 2130.82. The Dow was up 0.34 point to 18285.74, ending 0.1% below its most recent record of 18312.39.

The Dow and S&P both hit all-time highs this week, even as the week is on pace to be the slowest in stock trading since the week including New Year's Day. Trading has been quiet as traders say fewer investors are placing orders ahead of the long weekend. The stock market will be closed Monday for Memorial Day.

The Dow industrials have risen 0.1% for the week through Thursday's close. The S&P and Nasdaq are on track to post more substantial gains, up 0.4% and 0.8% in the same period, respectively.

"We've got the Dow and S&P touching new highs, but it doesn't seem to be with very much enthusiasm," said Colin Cieszynski, chief market strategist at CMC Markets.

In Europe, Germany's DAX slipped 0.4%, while France's CAC 40 was flat.

Federal Reserve Chairwoman Janet Yellen is scheduled to speak about the U.S. economic outlook at 1 p.m. ET.

In commodity markets, gold futures slipped 0.1% to $1202.70 an ounce. Crude-oil futures lost 1.5% to $59.79 a barrel. The yield on the 10-year Treasury note was at 2.207%, compared with 2.186% on Thursday. Yields fall as prices rise.

In corporate news, Deere & Co.'s shares rose 3.7% after the farm equipment producer reported its profit dropped in the latest quarter though results were still better than feared.

Campbell Soup Co. reported its profit easily topped expectations in the latest quarter as the company scaled back promotions and began implementing cost-cutting plans. Shares rose 2.4%.

AĆ©ropostale Inc. shares tumbled 17% after the teen retailer projected a wider-than-expected loss for the July quarter.
