LONDON, March 3 (Reuters) - Britain's top shares were 0.1 percent lower in midday trade on Wednesday as falls in energy stocks and drugmakers offset a rebound in life insurers and a rally by Vodafone.
At 1148 GMT, the FTSE 100 <
> was down 5.85 points at 5,478.21, having gained 1.5 percent to hit a six-week high on Tuesday.The index has rallied almost 9 percent since its year-low in early February when the FTSE was weighed by fears over the impact of monetary tightening in China and Greece's debt issue, and is now up 1.2 percent in the year to date.
"Given the strong gains of the past few sessions, it is not too surprising to see some sideways trading so far this morning," said Tim Hughes, head of sales trading at IG Index.
Energy stocks were the heaviest fallers. Cairn Energy <CNE.L> dropped 0.9 percent, pressured by a price target cut from Morgan Stanley, while BG Group <BG.L>, Royal Dutch Shell <RDSa.L> and BP <BP.L> fell 0.3-0.8 percent.
But oil explorer Tullow Oil <TLW.L> bucked the sector trend, rising 0.8 percent as Morgan Stanley said recent falls presented an excellent buying opportunity.
Investors banked profits in drugmakers following a recent strong run, with AstraZeneca <AZN.L>, GlaxoSmithKline <GSK.L> and Shire <SHP.L> off 0.6-0.7 percent.
The banking sector was weighed by a 1.7 percent fall from Europe's largest bank HSBC <HSBA.L>, which on Monday reported below-forecast numbers.
HSBC's shares have see-sawed over the past couple of days, recovering on Tuesday after Monday's sharp post-results fall.
Other banks, however, were in positive territory after Standard Chartered <STAN.L>, the emerging markets-oriented bank, posted in-line results and said 2010 started strongly. [
]Standard Chartered <STAN.L> added 2.5 percent, while Barclays <BARC.L>, Lloyds Banking Group <LLOY.L> and Royal Bank of Scotland <RBS.L> put on 0.8-2.5 percent.
Irish Life & Permanent <IPM.I>, up 3.8 percent said it sees Royal Bank of Scotland's <RBS.L> Ulster Bank unit as a potential partner for its banking unit in an expected consolidation. [
]Among individual issues, British Airways <BAY.L> shed 1.4 percent ahead of traffic data due at 1415 GMT.
Ex-dividend factors knocked 4.83 points off the FTSE 100 index on Wednesday, with Alliance Trust <ATST.L>, BHP Billiton <BLT.L>, Diageo <DGE.L>, Hammerson <HMSO.L> and RSA Insurance <RSA.L> all losing their dividend attractions.
INSURERS SHOW LIFE
Prudential <PRU.L> rose 4.3 percent after falling around 20 percent in the past two days since agreeing a $35.5 billion takeover of the Asian life business of AIG.
Market players also pointed to talk the fall in the share price may make it a takeover target for overseas companies.
Peers, Legal & General <LGEN.L>, Aviva <AV.L> and Standard Life <SL.L> also recovered after recent falls, up 1.5-3.3 percent.
Mobile telecoms heavyweight Vodafone <VOD.L> added most points to the FTSE 100 index, up 1.2 percent as BofA Merrill Lynch added the stock to its influential "Europe 1" investment list. [
]Miners were back on the front foot. Kazakhmys <KAZ.L>, Antofagasta <ANTO.L>, Xstrata <XTA.L> and Anglo American <AAL.L> were up between 0.8-1.9 percent.
On the economic front, the U.S. ADP Employment Report, Challenger U.S. jobs cut report and U.S. ISM non-manufacturing in U.S. are due for release on Wednesday, and will be watched as pointers towards Friday's key U.S. February non-farm payrolls. (Editing by Dan Lalor)
