NEW YORK (CNN/Money) - Blue-chips led a modest stock selloff Tuesday morning as investors backed out of equities after a four-session run up.

The Dow Jones industrial average (up 55.47 to 10,586.23, Charts) and the S&P 500 (down 3.30 to 1,219.51, Charts) index both lost around 0.5 percent in the early going.

The Nasdaq composite (down 7.02 to 2,171.22, Charts) saw a smaller decline.

Declines were broad-based, with 26 out of 30 Dow components sliding at the open, with no standouts to the downside.

The major gauges had risen for four sessions in a row as part of a broader rebound over the last few weeks. On Monday, falling oil prices had sparked a late-session advance.

The optimism that had fueled the advance seemed to remain in place, but after the rally stocks were vulnerable to a pullback Tuesday morning.

Among the movers, Toll Brothers (unchanged at $39.41, Research), one of the leading homebuilders, slumped after warning that 2006 new home deliveries and earnings would likely miss estimates. The warning overshadowed the company's stellar fourth-quarter revenue and earnings.

That weighed on the broader homebuilding sector, sending the Dow Jones Home Construction (up $19.12 to $922.13, Research) index down nearly 6 percent.

U.S. light crude oil for December delivery fell 9 cents to $59.38 a barrel in electronic trading.

Treasury prices rose, lowering the yield on the 10-year note to 4.59 percent from 4.63 percent late Monday. Treasury prices and yields move in opposite directions.

The dollar rallied to hit a two-year high versus the euro and slipped versus the yen.

COMEX gold rose 10 cents to $460.50 an ounce.

In global trade, major Asian markets mostly ended higher, with the exception of the Japanese Nikkei, while European markets were mostly higher at midday.
