A disappointing jobs report and negative outlooks for telecoms sent the Dow Jones Industrial Average sliding last week. Ad holding company stocks performed better than the market as a whole, perhaps buoyed by expectations of a positive first quarter, said Jason Helfstein, director of equity research at CIBC World Markets in New York. "The stocks have had a good fourth quarter, and a healthy first quarter looks good," Helfstein said. "Right now, investors are waiting to see where some big reviews land, such as Time Warner and Masterfoods." On the Big Board, Omnicom's shares fell 1.1 percent to close the week at $86.52, while IPG's stock price increased 5.1 percent to $16.41. WPP, trading as American Depository Receipts on the Nasdaq, climbed 5.9 percent to finish at $53.54.
