WPP was up 2.2% today at 715p, the highest the stock has been for almost three weeks.
There was still no response from Havas Advertising, which has so far failed to respond to WPP's 555p counter-bid on Monday for media-buying group Tempus.
There is every expectation that Havas will come back with a bid by next week. On the Bourse in Paris, Havas was up 0.5% to €10.39 (£6.57).
There was little movement on Tempus. Its stock was down fractionally at 580p. At that price, it is considerably above WPP's offer and Havas's original 541p bid.
Just outside of the media triangle, Aegis, which itself could easily become a target in the takeover battle for Tempus, was at 113.7p, up fractionally on the day and steady on the week.
