Tech stocks tumbled and the broader market also limped lower Monday, as early optimism gave way to profit-taking in 2005's first session.

The

Dow Jones Industrial Average

ended down 53.58 points, or 0.5%, to 10,729.43, its fourth straight loss since hitting a 2004 high last week. The

S&P 500

fell 9.84 points, or 0.8%, to 1202.08, and the

Nasdaq

shed 23.29 points, or 1%, to 2152.15, their biggest one-day point losses in a month.

The Nasdaq's skid was all the more worrisome given that the index rose in the day's opening hour. From its high point, the Comp fell 42 points Monday.

Volume on the

NYSE

was 1.50 billion shares, with decliners beating advancers by a ratio of almost 3 to 1. Volume on the Nasdaq was 2.19 billion shares, with decliners outpacing advancers by a ratio of about 7 to 3.

In other markets, the 10-year Treasury bond was up 1/32 in price to yield 4.21%, while the dollar was higher against the yen and euro. Gold was down $8.70, or 2%, its lowest level since November.

Energy prices eased as the northeastern U.S. continued to enjoy unusually mild weather. In Nymex floor trading, the February crude contract ended down $1.33 to $42.12 a barrel. The Philadelphia Stock Exchange oil index was off 3.7%, with all 15 components each posting losses of 2% or more.

On the economic front, the Institute for Supply Management's manufacturing index hit 58.6 in December, just above the 58.5 consensus forecast. The index registered 57.8 in November. But a subindex on employment showed a steep decline from 57.6 to 52.7. In addition, a report on construction spending showed an unexpected decline in November. Spending was down 0.4% vs. expectations for a 0.5% gain.

Chip stocks were notably weak, with the Philadelphia Semiconductor Index falling 2.1%. All 19 of its components ended in the red.

"The semiconductors for the last couple of weeks have shown a disconnect from the market and the Nasdaq, and has been the weakest sector," said Barry Hyman, equity market stratagist with Ehrenkrantz King Nussbaum. "It says that expectations may be a little too high for some of these growth sectors.

"It's a foreshadowing of how the market may react as we get deeper into this quarter, especially with worries about the fourth-quarter earnings coming out," Hyman said.
