U.S. stocks ended slightly lower on Thursday after European Central Bank President Mario Draghi brushed off pressure for more immediate monetary policy action but said the issue would be addressed early next year.

The day's losses were slight but broad, with seven of the ten primary S&P 500 sectors ending in negative territory and no sector up more than 0.3 percent.

Draghi said the ECB would reassess the impact of its stimulus early in 2015 and take further action if necessary, but didn't mention a specific timeline.

The S&P 500 fell as much as 0.6 percent before rebounding and briefly turned positive. The Dow had touched an intraday record.

"I wasn't expecting much from the ECB, which doesn't want to paint itself into a corner, but eventually we'll need to see action, not just words," said Matt Lloyd, chief investment strategist at Advisors Asset Management in Monument, Colorado.

The ECB met under growing pressure to prevent the bloc's economy from entering recession. The bank has already cut borrowing costs to record lows, given cheap loans to banks, and started buying debt to kick-start lending and bolster growth.

"We expect more stimulus will eventually happen, and it will really help the European economy," said Lloyd, who helps oversee $16 billion in assets. "We're very bullish on Europe going into next year."

The Dow Jones industrial average .DJI fell 12.52 points, or 0.07 percent, to 17,900.1, the S&P 500 .SPX lost 2.41 points, or 0.12 percent, to 2,071.92 and the Nasdaq Composite .IXICdropped 5.04 points, or 0.11 percent, to 4,769.44.

The day's losses were concentrated in energy shares, where the S&P Energy sector .SPNY lost 0.8 percent alongside a 1 percent drop in the price of crude oil. ConocoPhillips (COP.N) fell 2.1 percent to $69.31 while Chevron Corp (CVX.N) was off 1.3 percent at $112.28.

The moves follow three days of gains, when the group advanced 3.2 percent.

Microsoft Corp (MSFT.O) rose 1.6 percent to $48.84, limiting the decline in all three major indexes. Earlier, Barnes & Noble Inc (BKS.N) struck a deal to buy Microsoft's stake in Nook Media LLC in a deal valued at $125 million. Shares of Barnes & Noble fell 5.4 percent to $21.03.

Investors are looking ahead to the government's non-farm payrolls report for November, due before the market opens on Friday. Expectations are that the U.S. economy created 230,000 jobs last month.
