Shares of CMG, one of the more reticent hi-tech companies, have joined in the fun, nearly trebling. They are now on a spectacular rating. Stockbroker Granville expects profits of pounds 47.3m. Last year the group hit pounds 38.6m.
The rest of the stock market put on a resilient display with Footsie improving 56.1 points to 5,898.4. The supporting indices also made headway.

Royal & Sun Alliance suffered the expected correction, off 45p to 655p, as Tuesday's rogue order driven trade was rubbed out.
Among the best performing leaders were BAT Industries, up 28.5p to 581.5p on Swiss buying, often a sign that corporate activity is in the wind, and Railtrack, back on the main line with a 41p gain (after 95p) on its results and its involvement in the high speed rail link between London and the Channel Tunnel.
Courtaulds, the chemical group, fell 21.5p to 444p as the American PPG Industries decided not to bid, leaving the way clear for Akzo Nobel, the Dutch group which has made a 450p cash offer.
MFI Furniture, the struggling retailer, was back in the takeover frame with Ikea, the Swedish group, punted as a possible predator. The shares rose 5.5p to 87.5p in brisk trading. Before trading prospects deteriorated the shares were riding at 160p.
Storehouse, ahead of an investment dinner at London's Savoy Hotel, hosted by Henderson Crosthwaite, shaded 1.5p to 274.5p.
Queens Moat Houses, the hotel chain which once teetered on the brink of collapse, softened 0.5p to 35.5p as Salomon Smith Barney, the US securities group, emerged as a 14.63 per cent shareholder.

Trading warnings made predictable impacts. Future Integrated Telephony fell 15.5p to 36p after forecasting a "substantial" loss. Kevin Clarke quit as managing director.
Theo Fennell lost 7p to 57.5p; the luxury goods group said year's figures would be hit by overseas expansion.
Tandem, the cycle maker, hardened 0.25p to 8.75p as a shareholders' revolt emerged. Investors with 16.2 per cent want to replace three directors with members of their consortium. The idea, it appears, is to pump a racecourse business run by consortium member John Sanderson into Tandem. Mr Sanderson's company manages the Catterick, Doncaster and Redcar courses. Loss-making Tandem's peak was 20.5p, hit two years ago.
Galen, the health group which came to market in July, fell 30p to 415p. The shares have been weak lately. Finance director Geoffrey Elliott said he doubted if there had been a leak of the profit announcement due later this month. Any leak "wouldn't provoke a sale", he said.
The fall, he said, was caused by selling by small shareholders. "There is no institutional selling," he maintained. The shares were placed at 150p; they peaked at 527.5p.
Packaging group MY Holdings firmed to 82.5p as stockbroker Albert E Sharp said a re-rating was overdue. It expects a modest profits advance to pounds 14.55m this year.
