NEW YORK (MarketWatch) -- The optimism that sent indexes to new intraday highs after the European Central Bank's surprise interest-rate cuts Thursday had fizzled out by the end of the session, as indexes dipped into the red.

Analysts said that markets were overextended after a big run-up over the past four weeks, which made the S&P 500's and Dow Jones Industrial Average's pullback Thursday afternoon unsurprising. The modest retreat comes as investors await the monthly jobs report set to be released on Friday.

Both indexes reached intraday highs late Thursday morning after the ECB moves, but their gains faded as the session wore on.

The S&P 500 (SPX) lost 3 points, or 0.2% to 1,997.60. The Dow Jones Industrial Average (DJI) closed down 8.8 points, or 0.1%, at 17,069. The Nasdaq Composite (RIXF) fell 10.3 points, or 0.2%, to 4,562.20.

Market-moving economic news: The European Central Bank unexpectedly lowered key interest rates. Also read: The reluctant firefighters at the ECB start dousing the flames.

In the U.S., the day's economic data painted a picture of continued economic growth. The ADP report on hiring in the private sector showed private-sector hiring was almost unchanged from July. Weekly jobless claims numbers rose slightly more than expected, but remained near an eight-year low. Meanwhile, a gauge of activity for U.S. services and other nonmanufacturing companies reached its highest rate since 2008.

Those reports are merely a prelude to the closely-watched August jobs report on Friday. Economists on average are forecasting that .

On the Fed watch, Cleveland Federal Reserve President Loretta Mester argued the Fed should rework its forward guidance to convey that the first rate increase will depend on economic conditions and the speed of its progress toward the Fed's twin goals of low unemployment and stable prices. The Fed will debate the wording of its forward guidance at its next policy committee meeting on Sept. 16-17. Mester is a voting member this year.
