George W. Bush’s election win, coupled with a drop in oil prices and healthy October employment numbers, pushed stocks to their best weekly performance since March 2003. The Dow Jones industrial average ended at 10,388, having gained 3.6 percent in the last five days. The Nasdaq rose 15 points to 2,039, up 3.2 percent after a week of daily gains. Third-quarter results from Paris-based companies Publicis, which said organic revenue grew nearly 5 percent, and Havas, which reported an organic- revenue increase of 2.1 percent, appeared to have little effect on stock prices in the U.S. industry sector. IPG, which reported an unexpected net-income loss of $578.4 million, or $1.40 per share, recovered to close at $12.46 on the week, up 1.4 percent. Omnicom rose 2.2 percent to $80.53. WPP, trading as American Depository Receipts on the Nasdaq, climbed 3.1 percent to $51.80.
