The surge means that half of one of the market's favourite bets has turned out to be a winner. Unfortunately most speculators had ignored Unitech, opting for the other half of the two-way bet, Eurodisc Electron.
It all started when Elektrowatt, the Swiss group controlled by the Credit Suisse bank, acquired Landis & Gyr, an electronics group. To help meet the pounds 1bn outlay the Swiss decided to sell peripheral investments, including 29.4 per cent of Unitech and 42 per cent of Eurodisc, an electronic components company they helped put together last summer.
Much of the speculation swirled around Eurodisc, which seemed to be the more likely takeover target.
In the event, Unitech, which missed the speculative whirl, has become the bid target while Eurodisc still awaits a suitor. The activity was enough to lift Eurodisc 11p to 295p. It has been as high as 312p with the market talking of a bid in the region of 360p.
Unitech is likely to fall to Siebe, the engineer. Late on Friday it disclosed it had picked up 25 per cent and had options on the rest of the Swiss stake. Talks will now take place. Unitech, which controls Nemic Lambda, a Japanese power supply group, is thought to want any bid to include a cash alternative.
Some, such as Societe Generale Strauss Turnbull, expect any bid to be worth 750p; others hover around 650p. Siebe lost 18p to 826p.
The rest of the market moved ahead although trading was rather lacklustre. The FT-SE 100 index jumped 24.8 points to 3,669.6 with continuing takeover speculation and a firm New York opening the main influences. Dividend payments, representing 11.8 points, masked the strength of the advance.
Cable and Wireless, reflecting the potential BT interest, gained 9.5p to 485p. BT rose 4p to 351.5p. A Cable take-out price is the subject of intense debate. The group's overseas interests, including its controlling stake in Hongkong Telecom, cloud the issue. Lehman, the US securities house, puts the bid price between 570p and 670p.
Insurance shares were firm, largely on the back of Credit Lyonnaise Laing support. Banks continued to recover from last week's mauling prompted by the lending war.
GEC fell 5p to 359.5p as it denied reports of a pounds 5n deal with United Arab Emirates. It did confirm that Lucas Industries' chief executive, George Simpson, would succeed Lord Weinstock as managing director. Lucas, little changed at 192p, is now seen as vulnerable to a bid.
National Power and PowerGen, somewhat surprisingly, greeted a delay in the monopolies examination of their proposed moves into the regional electricity industry by moving ahead. NP rose 9.5p to 471p and PG 11.5p to 518p.
Allied Domecq, the retailing and spirits group, rebounded 10.5p to 491p after Friday's sell-off. Takeover hopes were said to be responsible for the recovery. United Biscuits, another group where a bid is seen as a possible solution to its problems, firmed 4p to 246p.
Zeneca, another takeover favourite, ended 8p lower at 1,375p after stripping out a near 25p dividend. Elsewhere on the drugs front, Stanford Rook gained 30p to 510p ahead of figures and SkyePharma was duly suspended at 9p to accommodate a major acquisition.
BAT Industries had a volatile session, despite a "clear the air" over its legal problems in the US. The shares ended 12p lower at 488p after hitting 482p. They were tormented by a sharp fall in the shares of Philip Morris, the US group unsettled by one of its executives giving evidence to the Food and Drug Administration.
NFC, the old National Freight Corporation, which has had a torrid time in recent years as a succession of profit warnings have devastated the shares, moved ahead 3p to 155p with NatWest Securities making positive noises. The shares, it said, could "be about to turn".
The day's profit warning was contributed by Rainford, an electrical equipment group, which slumped 92p to 282p.
A warning that write-downs could result in an $87m loss hit XCL, the oil exploration group, 3p to 16p. The shares were 102p in October.
Figures helped some shares higher. Pearson put on 7p to 664p; Doeflex, the chemical group, 20p to 238p and TT, a mini conglomerate, 18p to 311p.Reuse content
