LONDON, Nov 1 (Reuters) - Heavyweight Vodafone kept Britain’s top share index afloat on Friday as speculation about a bid from U.S. peers AT&T fuelled a rally in Europe’s largest mobile carrier.
Shares in Vodafone rose 3.2 percent to 231 pence, adding 13 points to the FTSE 100 after a media report that AT&T was exploring strategies for a potential takeover of the British telecoms firm as part of a push into Europe.
BofA Merrill Lynch, which sees the UK mobile company as a good cultural fit with AT&T, said it expects Vodafone’s shares to rise 27 pence and that a potential bid from AT&T could offer further upside.
Merger & acquisition activity in the European telecoms sector has been picking up pace in recent months as operators sell some of their assets to cut debt and overseas investors take advantage of some of the lowest valuations in decades in the sector, which has been hit by Europe’s economic crisis.
“M&A is a big sector theme in European telecoms currently,” said Guy Peddy at Macquarie Research, adding any AT&T bid for Vodafone was likely to be in the 250 pence - 255 pence range.
“European operators are in some cases looking to divest assets to de-risk but also the implied valuation of European assets is noticeably lower than other geographies so you’ll see more interest from overseas investors.”
The FTSE was up 2.51 points to 6,733.94 points at 1553 GMT. The index hit a five month high at 6,819 earlier this week and is up 12 percent from June.
Societe Generale’s derivative strategists said a rally in the FTSE was now likely to pause and recommended that investors sell options to buy the index at 7,000 points by December.
Curbing gains on the FTSE was state-backed lender Royal Bank of Scotland, down 7.6 percent after it posted worse-than-expected results that overshadowed its moves to deal with a $61 billion portfolio of bad debts.
Joining the country’s fifth biggest bank by capitalisation among top fallers was aircraft parts supplier Meggitt, down 11.3 percent and on course for its worst daily loss in 12 years after the company cut its full-year revenue guidance.
The two firms’ results added to a largely negative tone from corporate reports this week and drove heavy selling of both stocks, with volume more than three times their respective full-day averages for the past three months, compared with less than 74 percent for the FTSE 100.
As the earnings season passes the half-way mark, 53 percent of companies so far in the STOXX Europe 600 index have missed consensus expectations, compared with less than half in recent quarters, running somewhat counter to the growing optimism about Britain’s macroeconomic numbers.
Analysts have cut their estimates for next year’s earnings from British companies by 1.1 percent in the past 30 days and now the mean estimate from analysts with the best track record is for a 10.8 percent growth rate.
“We’re still waiting for this point when we can proclaim ‘yes earnings growth is picking up significantly’,” said Lars Kreckel, global equity strategist at Legal & General Investment Management.
“We’ve done a lot of pricing out of risk and... my base case is that equities have roughly an upside equivalent to the earnings growth that we can expect (next year).” (Reporting By Francesco Canepa, editing by Gareth Jones)
