Investors appeared unwilling to push the market significantly higher in the absence of news today, and following the milestone glimpsed in the previous session.

"There are two things at play in this market," said Kevin Caron, market strategist with Ryan, Beck & Co., LLC. "You’ve got fundamental conditions in the economy improving, but on the other hand you have the very human response of money managers, who are facing the year end and trying to position their portfolios after two or three down years."

According to preliminary calculations, the Dow closed down 1.56, or 0.02 percent, at 9,921.86. In the previous session, the index blipped above 10,000 for all of a minute.

The broader gauges were also essentially flat today. The Nasdaq composite index shut down 3.67, or 0.2 percent, at 1,904.65. The Standard & Poor’s 500 index fell 1.13, or 0.1 percent, to 1,059.05.

Investors were euphoric when the Dow tipped 3 points over the 10,000 mark yesterday, but they pulled back after the market failed to accelerate convincingly. They sought more profits when the Federal Reserve indicated interest rates would stay low for now.

"There’s a lot of information out there from yesterday," said Brian Williamson, an equity trader at The Boston Company Asset Management. "But you have to think the market has moved and is thinking about the next numbers that will tell us one way or another where rates are going to go."

Stocks have pushed higher for several weeks but analysts have questioned whether the values are justified, and the market remains vulnerable to the possibility of disappointing economic data and corporate earnings. Analysts were keeping a close eye on the Labor Department’s reports on producer and consumer prices, expected over the next week.

Luxury home builder Toll Brothers Inc. closed down $1.58 at $37.87 despite reporting better than expected earnings on strong revenue and orders for new homes. The entire sector broadly declined amid concerns about falling mortgage demand.

BellSouth closed down 25 cents at $26.96 after Morgan Stanley cut it to "equalweight" from "overweight," in part because of concerns that the stock was overvalued. The telecommunications firm has gained more than 20 percent since the end of the first quarter.

AutoZone Inc. ended the day down $11.09 at $80.25 after reporting first-quarter earnings that beat analyst expectations by 7 cents a share.
