NEW YORK (TheStreet) -- Stocks were mixed on Friday as the U.S. dollar spiked on stronger-than-expected consumer price data, putting pressure on crude oil and the energy sector. 

The S&P 500 was down 0.05% and the Dow Jones Industrial Average fell 0.13%.

The U.S. dollar spiked against a basket of international currencies, a response to signs the Federal Reserve will tighten interest rates as other major global economies introduce or show signs of furthering monetary stimulus. The rise in the dollar caused West Texas Intermediate to fall from its May record, slipping 1.2% to $60.02 a barrel. 

The Nasdaq added 0.19%, lifted by a rally in enterprise software stock Intuit (INTU). Shares were higher after the company beat third-quarter estimates and increased its expectations for subscribers to its QuickBooks Online program by the fourth quarter. 

A surprisingly strong core consumer price reading also made the case for an interest rate this year, according to a strategist. U.S. core consumer prices rose at a faster pace than expected in April. Headline CPI rose 0.1%, as expected, while core prices excluding energy and food spiked 0.3%, the fastest pace since January 2013. Core prices climbed on rising shelter and medical care costs. Economists had expected core CPI to increase 0.1%.

"The stability seen in core prices has to be encouraging for those on the Fed's board who see support for a rate hike later this year," said Dan Greenhaus, chief strategist at BTIG. "While much attention is paid to Fed President Evans' dovishness, core members including Janet Yellen and Bill Dudley appear to favor raising interest rates in 2015, however modestly that rate adjustment may be. Today's data plays into thought process."
