Higher Still

The Dow managed to close slightly above 12,000 last week, despite some investor skittishness over the economy’s future. The index of 30 blue-chip stocks closed at 12,002.37, up 44.67 points, a 0.4 percent gain. But strong earnings from Google couldn’t boost the Nasdaq , which closed down 16.89 points at 2,342.30, off 0.7 percent. Most ad companies also finished higher. Omnicom closed relatively flat at 94.79. WPP Group posted a 2 percent gain to finish at 63.13. Interpublic Group was up 1 percent at 10.58. Publicis Groupe finished lower at 38.47, down nearly 1 percent.
