* Carphone pares losses after 19 pct drop to lifetime low
* Energy and mining sectors lend support
* Retailers suffer on tough trading outlook
By Dominic Lau
LONDON, June 12 (Reuters) - Britain's top share index bounced back with a gain of 0.8 percent by midday on Thursday after a four-day losing run, as rising oil and mining stocks offset a slump in Carphone Warehouse <CPW.L> and retailers.
By 1121 GMT, the FTSE 100 <
> was up 45.9 points at 5,768.8 after shedding 1.8 percent on Wednesday to hit its lowest closing level since March 31."When we get a market which has been generally negative for so long, then obviously you are going to get days when you have a bit of bounce," said Peter Dixon, UK economist at Commerzbank.
Dixon added energy shares were doing well, and oil majors could still extract a significant premium from each barrel of oil sold, and would do so for some considerable time.
"(But) it's difficult to remain positive. Equities generally are going to take a cue from what happens in the U.S."
A tough trading outlook weighed on Home Retail <HOME.L>, Britain's biggest household goods retailer, which posted flat first-quarter underlying sales at its main Argos chain. Home Retail fell nearly 7 percent.
The Times quoted Philip Green, who owns the Topshop fashion chain, as saying that the worst of the credit crunch has yet to hit the high street, offering the latest sign that retailers may not feel its full effects until next year.
"The credit market crisis is well into the second half," said Howard Wheeldon, senior strategist at BGC Partners.
"It's going to get a lot worse before it gets better ... You could say this is the delayed-action shock that a lot of people were expecting for much of the last six to nine months. It's now turning into reality."
Carphone Warehouse fell by as much as 19 percent to hit an all-time low before trimming losses, after Europe's biggest independent mobile retailer said broadband demand slowed and was cautious about the year ahead. Carphone Warehouse was still down 8 percent after 17.5 million shares had changed hands by 1121 GMT, compared with a 30-day daily average of 8.54 million.
RETAIL SECTOR UNDER PRESSURE
Britain's general retail sector <.FTASX5370> has fallen 20 percent in the past month, and 12 percent in the past week, as a string of data has pointed to a slowing economy, while rising inflation has damped hopes of interest rates cuts.
Within the retail sector, Next <NXT.L>, Kingfisher <KGF.L> and Debenhams <DEB.L> were down between 0.8 and 5.2 percent.
Tougher lending terms have forced Britain's first-time home buyers to put down average deposits of 13 percent in April, the highest level in more than three years, the Council of Mortgage Lenders said. [
]Oil shares were generally in demand, with BP <BP.L> adding 0.8 percent and Royal Dutch Shell <RDSa.L> rising 0.3 percent.
Miners also gained, with BHP Billiton <BLT.L>, Rio Tinto <RIO.L>, Vedanta Resources <VED.L>, Lonmin <LMI.L>, Antofagasta <ANTO.L> and Anglo American <AAL.L> up between 0.7 and 3.3 percent.
Investors awaited U.S. retail sales at 1230 GMT for further insight into the health of U.S. consumer spending. U.S. index futures pointed to a higher opening on the Wall Street.
Traders said short-covering pushed shares in HBOS <HBOS.L> up 13.5 percent. Royal Bank of Scotland <RBS.L>, Standard Chartered <STAN.L>, HSBC <HSBA.L> and Lloyds TSB <LLOY.L> gained between 0.5 and 5.0 percent. (Additional reporting by Michael Taylor and Atul Prakash, editing by Will Waterman)
