For the second day running US financial markets remained closed following Tuesday's terrorist attacks in New York and Washington.

At present, the impact of the outrage on the world’s advertising industry can be estimated only by stock price performance in non-US markets.

At close of trading yesterday on the London Stock Exchange WPP Group slid 5.73% to £5.57 ($8.18) while Cordiant Communications edged down by 5.7% to £1.39 ($2.04).

On the Paris Bourse, Havas Advertising was down 11.94% at E7.60 ($$6.89) by the end of the day and Publicis Groupe had slipped 4.29% to E20.10 ($18.22)
