Blue-chip stocks staged another late-day rally to lock in solid gains Wednesday, sparked by a plunge in oil prices, while tech stocks were forced slightly into the red by weakness in semiconductors.


Dow Jones Industrial Average

closed up 60.32 points, or 0.59%, to 10,262.97; the

S&P 500

added 3.80 points, or 0.34%, to 1125; and the

Nasdaq Composite

was off 1.79 points, or 0.09%, to 1988.98.

The 10-year Treasury note traded down 8/32 in price to yield 4.73%, while the dollar was lower against the yen and higher vs. the euro.

The Dow's rally took the index above its 50-day moving average of 10,251; all three indices are now above that technically significant level.

Trip Jones, managing director at SunGard Institutional Brokerage, attributed the afternoon rally to a short-term, overbought condition in the market. "The volume and breadth in the market shows absolutely no conviction in this move," he said.

"We don't think this market has finished its adjustment," Jones added. "We think this is a relief rally in a larger correction. Given the lack of volume in this thing, I'm not impressed at all."

More than 1.2 billion shares were traded on the

Crude-oil futures eased after Kuwait's Oil Minister Sheikh Ahmad Fahad Al-Ahmad Al-Sabah said OPEC could add 700,000 million barrels a day of real crude to the world's oil markets. Earlier, Qatar's energy minister suggested OPEC members should "produce what they want" in the near future to avoid price shocks. According to


, Abdullah bin Hamad al-Attiyah said the cartel is near a consensus to raise output by 2.5 million barrels a day when it meets Thursday in Beirut.

Saudi Arabia said its security forces killed two key militants with alleged ties to a shooting attack and hostage-taking in eastern Saudi Arabia that killed 22 people over the weekend, according to the

In Iraq, insurgents loyal to radical Shiite cleric Muqtada al Sadr fought U.S. forces near a mosque in Kufa and Baghdad, and officials said six Iraqis were killed and 40 others wounded. Elsewhere, a third fatal car bomb in as many days exploded in a Sunni Muslim district of Baghdad, killing at least five people and wounding about 33 others, including children, police said.

John Hughes, equity strategist at Shields & Co., said he thinks the market's ability to shake off both the news of violence in the Middle East over the weekend and record-high oil prices show that these negative factors, which have been weighing on stocks for weeks now, already are factored into the equation for investors and people are ready to trade on other positive factors.

"I think it's kind of built in now, and I think the fact that the market was able to take it in stride is important," Hughes said. "It's become sort of old news. Going forward, people are looking for a positive catalyst out of the Middle East or second-quarter earnings forecasts or a good employment number on Friday.

"We're a little overbought here on a short-term basis after last week's gains, so you might see some back-and-fill action for a couple of days leading up to these economic reports coming up," he added. "On balance, I think we're going to continue to see things push higher here."

Trading volume remains muted ahead of Friday, when the government will release its all-important employment report for May. Nonfarm payrolls are expected to have added 215,000 jobs, down from the 288,000 reported in April. Meanwhile, the unemployment rate is expected to stay flat at 5.6%.
