NEW YORK (MarketWatch)--U.S. stocks reversed gains on Thursday, as sentiment turned sour when selling in momentum stocks intensified.

Optimism following better-than-expected jobless claims and dovish comments from European Central Bank President Mario Draghi, who said the ECB stood ready to act in June, faded by midafternoon.

The S&P 500 (SPX) was a point lower at 1,879.29, hovering near its record closing level.

The Dow Jones Industrial Average (DJI) rose 33 points, or 0.4%, to 16,579.30, after topping its previous closing high earlier.

The Nasdaq Composite (RIXF) was 6 points, or 0.2%, lower at 4,066.53.

The Russell 2000 (RUT) index of small stocks gave up gains and was 2 points, or 0.1%, lower at 1,106.10.

"A large drop in jobless claims this morning set a positive tone," said Chris Gaffney, senior market strategist at EverBank Wealth Management.

"In the absence of bad news, a combination of a better-than-expected jobless report, comments from the Fed that the rates will stay low and Draghi's mention of easing action in June, drives markets higher," he added.

Federal Reserve Chairwoman Janet Yellen appeared before the Senate Budget Committee in her second day of testimony before Congress to discuss the central bank's economic and fiscal outlooks.

Among her memorable comments were the ones about the middle class the student debt: Answering questions from the senators, Yellen said that the shrinking of the middle class is a disturbing trend and student debt is preventing people from buying homes and that is affecting the housing market.

In economic news, the number of people who applied for new unemployment benefits last week fell to the lowest level in a month, but the decline likely stemmed from seasonal quirks instead of any major change in hiring trends or layoffs.

Initial jobless claims dropped by 26,000 to a seasonally adjusted 319,000, the Labor Department said Thursday. Economists surveyed by MarketWatch had expected claims to fall to 325,000 in the week ended May 3.
