Wall Street slips at opening bell

NEW YORK (CNNMoney.com) -- Stocks opened lower Tuesday as investors looking for a flight to safety continued their move to bonds.

The Dow Industrials and the S&P 500 posted modest losses as the Nasdaq showed little change.

Treasury prices rose, taking the yield on the benchmark 10-year note to 4.6 percent from 4.63 percent late Monday, although that yield was up from the lows of the morning. Bond prices and yields move in opposite directions.

Target (Charts, Fortune 500), the nation's No. 2 discount retailer, reported earnings that met Wall Street forecasts, and reaffirmed its earlier guidance.

Oil prices fell in early trading, even as Pemex, Mexico's state-owned oil company, abandoned its offshore oil rigs just ahead of Hurricane Dean, which was making landfall as on Yucatan coast Tuesday morning as a monster Category 5 storm.
