LONDON, July 28 (Reuters) - Weak energy issues dragged Britain's top share index lower by midday on Wednesday, with BG Group <BG.L> a big faller on its quarterly results, although heavyweight miners and banks held firm.
At 1111 GMT, the FTSE 100 <
> index was down 24.58 points at 5,341.13, having hit an early peak of 5,398.10, just below resistance at 5,399 and the psychologically important 5,400 level."It's running out of steam a bit ... I hate to use the words profit-taking, but anyone involved in running these stocks up since the beginning of the earnings season and the end of the European banks stress tests is probably sitting on some decent gains," said David Morrison, market strategist at GFT Global.
"Maybe we have just run up too far, too fast," Morrison said.
Falls by integrated oils was the main drag on the blue chips around midday, with BG Group <BG.L> the worst sector performer after its second-quarter numbers failed to excite. [
]"Although BG's second-quarter figures were above consensus, we do not see any strong drivers of near-term share price performance in the results," said Collins Stewart in a note.
Peers BP <BP.L> and Royal Dutch Shell <RDSa.L> shed 1.5 and 0.3 percent, respectively, with crude prices <CLc1> also lower.
Investors had a deluge of other corporate earnings news to digest on Wednesday.
Invensys <ISYS.L> was the top FTSE 100 faller, losing 6.1 percent after the engineer's trading update raised concern over its Rail division's performance for Nomura, which cut its estimates for the firm. [
]Beverage-can maker Rexam <REX.L> shed 4.1 percent as the firm said visibility remained low and the global economic outlook uncertain after posting an above-forecast rise in underlying first-half pretax profits. [
]Weakness in heavyweight drugmakers also weighed on the blue chips, with AstraZeneca <AZN.L> shedding 0.5 percent ahead of second-quarter results on Thursday, while GlaxoSmithKline <GSK.L> fell 1.4 percent as it traded ex-dividend on Wednesday.
Scottish & Southern Energy <SSE.L>, down 4.2 percent, also traded without its payout attractions.
BANKS BOOSTED
Banks were the best performing blue chips on a sector basis, extending the rally made since Friday's publication of European stress tests on the sector, and after Basel regulation news.
The sector was helped by an upgrade in strategy rating by Deutsche Bank to "neutral" from "underweight", with the broker noting the Basel Committee on Banking Supervision's decision to make a "less stringent" set of regulatory recommendations.
HSBC <HSBA.L> was the top banking gainer, up 1.2 percent, in demand ahead of second-quarter results due next Monday, while Royal Bank of Scotland <RBS.L>, Barclays <BARC.L>, and Standard Chartered <STAN.L> added between 0.2 and 0.6 percent.
Lloyds Banking Group <LLOY.L> missed out on the rally, however, shedding 2.1 percent. The bank has shelved plans to sell off its 60 percent stake in mid-cap wealth manager St James's Place Capital <SJP.L>, which rose 4.6 percent. Miners also lent their strength to the blue chips, led by Xstrata <XTA.L>, up 1.5 percent after metal prices rose and copper hit its highest levels since mid-May, helped by an assurance from China on the economic growth outlook.
Bank of England Governor Mervyn King and fellow Monetary Policy Committee members Charles Bean, Paul Fisher, David Miles and Andrew Sentance took questions on the May Inflation Report from parliament's Treasury Committee on Wednesday.
"I am arguing that we have room to use monetary policy in either direction. I don't want to pre-judge where it will need to go. Our view so far has been is that we have not need to move in either direction, but we are prepared to do so in either direction, as seems appropriate," said BoE's King.
Adding to the picture of recovery in the UK, house prices in England and Wales rose 0.1 percent on the month and 8.4 percent on the year in June, figures from the Land Registry showed on Wednesday. [
