Dollar climbs to 12-year high against yen

U.S. stocks were trading lower early on Thursday as investors grappled with comments from Federal Reserve officials about the possibility of raising interest rates this year.

John Williams, president of the San Francisco Fed (http://www.marketwatch.com/story/feds-williams-argues-against-using-monetary-policy-to-address-stability-concerns-2015-05-28)said the U.S. central bank is likely to raise rates later this year, reiterating Chairwoman Janet Yellen's view, expressed on Friday. Speaking to the Monetary Authority of Singapore, Williams also said the central bank shouldn't use interest-rate policy to address risks to financial stability.

The S&P 500 (SPX) slipped 9 points, or 0.4%, lower at 2114. The Dow Jones Industrial Average (DJI) dropped 85 points, or 0.4%, to 18,076. The Nasdaq Composite Index (RIXF) was down 22 points, or 0.4%, at 5082, retreating from the record level reached on Wednesday.

Tim Dreiling, senior portfolio manager at the Private Client Reserve at U.S. Bank, said recent trading pattern of the S&P 500 index suggests we are in the waiting game before the first rate hike.

"The trading range of the S&P 500 has tightened and we expect further summer slowdown, as there is not going to be much to jolt the market in either direction until the Federal Reserve begins raising interest rates. The Fed is most likely to start in September, but it will not do anything that will be disruptive to the markets," Dreiling said.

Market reaction to weekly jobless claims data was mostly muted. A jump in weekly jobless claims was bigger than expected; however, the pace of layoffs still remained near a record low.

Data: The number of people who applied for unemployment benefits (http://www.marketwatch.com/story/jobless-claims-climb-to-five-week-high-of-282000-2015-05-28)in late May rose to a five-week high. Initial jobless claims climbed by 7,000 to a seasonally adjusted 282,000 in the week ending May 23, the Labor Department said Thursday.

A gauge of pending home sales (http://www.marketwatch.com/story/aprils-gauge-of-pending-home-sales-highest-in-nine-years-2015-05-28)increased in April for the fourth consecutive month to reach the highest level in nine years, signaling that upcoming deals could pick up, a trade group said Thursday.

Looking ahead, market watchers also are awaiting a revision of U.S. first-quarter gross domestic product due Friday and a report on consumer sentiment.

Fed speakers: At 2:45 p.m. Eastern Time, Minneapolis Fed President Narayana Kocherlakota will give a speech on monetary policy in Helena, Mont. Kocherlakota isn't a voting member of the Fed's policy-setting committee this year.

Speculation that the Fed will move on rates later this year has recently supported the dollar, with the greenback (USDJPY) jumping to a 12-year high against the yen (http://www.marketwatch.com/story/dollar-taps-a-12-year-high-against-yen-2015-05-28) on Thursday.

Abercrombie & Fitch Co.(ANF) reported a wider-than-expected loss during the first quarter, but the retailer gave an optimistic outlook for the rest of the year, sending shares up 10%.
