NEW YORK Wall Street has ended a wobbly session with mixed results as concerns about the financial sector eroded enthusiasm over a decline in oil prices and a report that signaled modest growth in the service economy.
The latest worries about financial companies flared after Moody's Investors Service warned it might downgrade its ratings on bond insurers Ambac Assurance Corp. and MBIA Insurance Corp. That followed two days of sharp declines fueled by fears regarding more bank write-downs and concerns about Lehman Brothers Holdings Inc. liquidity.
Buoyed earlier by a decline in oil prices and a positive report on the service sector from the Institute for Supply Management, stocks moved from positive to negative throughout the session. Some investors looking to sidestep the troubled financial sector moved into technology stocks, giving the Nasdaq composite index the only advance for the major indexes.
According to preliminary calculations, the Dow Jones industrial average fell 12.37, or 0.10 percent, to 12,390.48.
Broader indexes were mixed. The Standard & Poor's 500 index fell 0.45, or 0.03 percent, to 1,377.20, while the Nasdaq rose 22.66, or 0.91 percent, to 2,503.14.
Bond prices fell as stocks advanced. The yield on the benchmark 10-year Treasury note, which moves opposite its price, rose to 3.92 percent from 3.89 percent late Tuesday. The dollar was mixed against other major currencies, while gold prices fell.
Hugh Whelan, managing director at Hartford Investment Management Co., said Wall Street will likely remain moored to its current levels until there is a sustained pullback in oil and until a more robust corporate profit picture emerges.
"I think broadly speaking we'll probably trade at a range over the next few months," he said. "From a valuation perspective the market is right where it should be given current profit levels."
He said some investors are gravitating toward technology stocks thinking that profits at such companies are likely to hold up better in a weak economy and that tech could be an early winner should the economy begin to show signs of picking up.
"It's just a sector that is not plagued by some of the worries that are foremost on people's mind," he said, pointing to concerns about credit quality that are dogging the financial sector and unease over the effect of rising energy prices on companies dependent on consumer spending.
The latest evidence of uneasiness about the financial sector came from Moody's announcement that it is reviewing the AAA insurance financial strength ratings for Ambac and MBIA. The rating agency said the "most likely" outcome of the review will be a downgrade. Ambac fell 51 cents, or 17 percent, to $2.49, while MBIA fell $1.06, or 16 percent, to $5.63.
One company in the financial space that weighed on the market Tuesday showed a rebound. Lehman Brothers Holdings Inc. rose 79 cents to $31.40 after Merrill Lynch raised its rating on the company. Lehman on Tuesday denied rumors that it had tapped the Federal Reserve's discount window because of cash problems. Reports Tuesday that the investment bank needs to raise up to $4 billion in capital touched off further concerns about the health of the financial sector.
J.M. Smucker Co. said it agreed to acquire the Folgers coffee brand from Procter & Gamble Co. in a nearly $3 billion stock deal. Smucker slipped 12 cents to $53.87, while P&G advanced $1.04 to $66.45.
United Airlines parent UAL Corp. rose 61 cents, or 7.2 percent, to $9.14 after saying it plans to cut as many as 1,100 more jobs, remove 70 fuel-hungry aircraft from its fleet and reduce domestic capacity to trim costs in the face of surging energy costs. The nation's No. 2 carrier previously said it planned to cut 500 jobs and that it would mothball some of its least fuel-efficient aircraft.
Declining issues outnumbered advancers by about 8 to 7 on the New York Stock Exchange, where volume came to 1.3 billion shares.
The Russell 2000 index of smaller companies rose 4.71, or 0.64 percent, to 743.71.Overseas, Japan's Nikkei stock average rose 1.59 percent. Britain's FTSE 100 closed down 1.45 percent, Germany's DAX index fell 0.77 percent, and France's CAC-40 declined 1.38 percent.
