Seeboard is thought to be the next utility to attract takeover attention. In busy trading the shares moved to a new peak, up 9p to 472p.
Speculators, still basking in the success of spotting the Northern Electric bid action, feel Seeboard, currently valued at £1.1m, represents an ideal target for a conglomerate wishing to tap into the electricity industry's huge cash resources.
Seeboard was one of the electricity shares that resisted the predictable profit-taking following the big gains scored in the past few weeks.
Yorkshire Electricity's 90p super dividend and its proposal to hand National Grid shares to shareholders also powered the sector. Yorkshire, with the special dividend stripped out, fell 60p to 687p, an effective gain of 30p.
Waters were also firm, with investors taking the view they could emerge as takeover targets next year.
The utility excitement helped the stock market to turn in its best display for eight weeks. The FT-SE 100 index rose 40.2 points to end the week above 3,000 .
Futures activity helped squeeze prices higher but the outbreak of corporate action, even if the SG Warburg-Morgan Stanley merger talks ended in acrimony after only a week, continued to encourage interest.
With New York enjoying an impressive opening, the market was again happy to ignore the package of doubts and worries that have weighed heavily on shares since the autumn.
The expiry of the December Footsie futures contract went smoothly although some traders thought they detected a head-on tussle between Morgan Stanley and Smith New Court in the dying minutes.
But the anxieties are likely to resurface at any time, and although shares have made progress this week, with the FT-SE 100 up 36.3 in often eventful trading., the atmosphere remains fragile. Some of the more optimistic souls claimed the festive rally was actually under way, if more muted than in previous years.
With trading likely to be thin in the last two weeks of the year it would not take much buying interest to produce a spectacular upsurge.
Even so there is clearly no chance of a repetition of last year's record-breaking performance, when the index soared more than 350 points..
