Blue-chip stocks fell on Thursday as fierce fighting and a spate of kidnappings in Iraq pushed investors to take a cautious stance and sell stocks before the three-day holiday weekend.
Disappointment over Wal-Mart Stores Inc's profit prospects forced the Dow lower, while technology stocks held onto slight gains driven by a jump in earnings from Yahoo Inc and a bullish revenue forecast by Dell Inc.
"We started on a very positive note, but with the holiday weekend, there is a tendency to take a little money off the table," said Peter Dunay, chief market strategist at brokerage Wall Street Access.
On the eve of the anniversary of Baghdad's capture, US-led forces were locked in open urban warfare in Iraq's central Sunni town of Falluja, the Shia shrine city of Kerbala and Abu Ghraib on the western outskirts of the capital, witnesses said.
In addition, a number of South Koreans, Japanese and one Briton were involved in separate kidnapping incidents.
"The more this escalates, the worse this will be," said Dunay. "It is in the back of investors' minds."
Thin trading exaggerated the market's moves, with Wall Street modestly staffed through the Passover and Easter holidays. US financial markets will be closed on Friday in observance of Good Friday.

"These downdrafts are institutions exiting positions in front of the long weekend," he said.
Wal-Mart was the biggest drag on the Dow and the S&P 500 as the world's biggest retailer dashed hopes it would raise its profit forecast after some of its peers raised theirs. Its shares fell $1.29, or 2.2 percent, to $56.69.
General Electric Co's stock spent much of the session lower, but ended up 1 cent at $31.41 after it said quarterly earnings rose slightly on higher orders for industrial products. But GE also said investors will have to wait until 2005 for double-digit earnings growth.
