NEW YORK — Commodity prices recovered some of last week’s losses Monday, helping to lift the stocks of energy and materials companies. The broader market also rose despite new worries about Greece’s debt problems. Oil prices once again moved above $100 a barrel and pushed energy stocks higher. Marathon Oil Corp. rose 5.3 percent. Baker Hughes Inc., which helps companies drill for oil and gas, gained 3.4 percent. Energy companies within the S&P 500 rose nearly 2 percent, the most among the 10 industries in the index.

The S&P 500 added 6.09 points, or 0.5 percent, to close at 1,346.29. The Dow Jones industrial average gained 45.94 points, or 0.4 percent, to 12,684.68. The Nasdaq composite index rose 15.69 points, or 0.6 percent, to 2,843.25.
