United States stocks declined, with blue chips erasing early gains to fresh record highs, as investors grappled with concerns over what stronger-than-expected US growth might mean for Federal Reserve policy.
The Dow Jones Industrial Average slipped 20 points, or 0.1%, to 15,727 points. Earlier, the blue-chip barometer reached an all-time intraday high of 15,797.68 before pulling back.
The S&P 500 index lost seven points, or 0.4%, to 1,764 points.

The European Central Bank's surprise interest-rate cut provided an early boost for stocks.
The first read on third-quarter US gross domestic product showed growth of 2.8%, up from 2.5% in the second quarter and well above expectations of 2%. The price index for personal consumer expenditures--the Fed's preferred gauge for inflation--grew 1.9% versus forecasts of a 1.6% rise.

"People are conflicted between thinking growth is good, because growth gives us more profits, and thinking more growth means the Fed is inclined to start [reducing stimulus]," said John Rutledge, chief investment officer at New York-based global investment firm Safanad.
Investors continued to flip flop over expectations of Fed policy. Recently, there has been a growing belief that the Fed could start reducing stimulus measures, by cutting back on its $US85-billion-a-month bond-buying program, as early as December. Just two weeks ago, disappointing September jobs data had investors believing the Fed wouldn't move until March, or even June.
Rex Macey, chief investment officer at Wilmington Trust Investment Advisors, said investors continue to quibble over Fed policy. He said the GDP data were a "two-edged sword" because while "the headline number looked great, but a fairly big gain in inventories is a concern."

Investors will now turn their attention to the October US employment report due Friday.

Meanwhile, the trading debut of Twitter, the biggest technology initial public offering since Facebook last year, offered investors a distraction from the debate over economic data. Twitter opened at $45.10, well above the $26 IPO price, and held those gains in recent trading.

Earlier, the European Central Bank cut its benchmark interest rate to 0.25% from 0.5%. European equity markets initially rallied on the ECB's move, then erased those gains amid concerns the nascent recovery in Europe may be fading. The Stoxx Europe 600 closed virtually unchanged, paring early gains of as much as 1.5%.
The euro slumped to a near two-month low against the dollar before recovering slightly.
