Stocks rebounded yesterday from their worst week in three months, led by energy shares as refinery shutdowns following Hurricane Rita lifted oil prices. Insurers gained after damage from the storm was less than forecast.

Boeing, the world's largest aircraft maker, was the best performer in the Dow Jones industrial average after the company reached an agreement with its striking machinists.

The Dow average increased 24.04, or 0.2 percent, to 10,443.63. The Standard & Poor's 500-stock index rose 0.34, to 1215.63. The Nasdaq composite index gained 4.62, or 0.2 percent, to 2121.46.

Valero Energy, the nation's largest refiner, said its Port Arthur, Tex., plant might be shut for two to four weeks. Six other facilities in Port Arthur and Beaumont, Tex., and Lake Charles, La., may stay shut because of lack of power and damage from winds or flooding. None of the operators said when output would resume.

The stock market's rebound was limited by concern that rising fuel prices, exacerbated by the hurricanes, will dent consumer spending.

Walgreen fell $1.01, to $41.50. The company said fiscal fourth-quarter profit increased 1.4 percent, less than analysts' estimates, as Hurricane Katrina damaged property and boosted costs.
