LONDON, Jan 29 (Reuters) - Britain's blue-chip FTSE 100 index <
> extended earlier gains by midday on Tuesday, led by banks and miners, as hopes grew of an interest rate cut by the U.S. Federal Reserve this week. At 1140 GMT the UK's largest share index edged 88.6 points, or 1.5 percent, higher at 5,877.5 with trade relatively thin. The FTSE 100 has now lost 9 percent in 2008."It's still very fragile. The sentiment is still very nervous. There is genuine concern that the banks are still going to come out with some poor numbers from time to time, and more write-offs," said Tony Craze, a stockbroker at Dawntraders.co.uk on UK markets.
"Having said that, there are always opportunities," Craze said. "Markets overdo it on the upside and the downside and I think they have on the downside overdone some of these stocks."
Overnight, both U.S. and Asian markets rose after weak housing data cemented expectations the Fed will slash rates this week. The Fed will begin a two-day rate-setting policy meeting later in the day, with a decision due at 1915 GMT on Wednesday.
"There is a degree now of it being a case of how much the rate cut (will be). I still think it'll be a half (point)... any less than that would be a disappointment," Craze said.
Sectors boosted by the positive sentiment included banks, with vague M&A talk also driving shares. HSBC <HSBA.L>, HBOS <HBOS.L> and Royal Bank of Scotland <RBS.L> all gained between 1.7 and 3.1 percent. However, Alliance & Leicester <ALLL.L> (A&L) shares slipped 0.6 percent after the bank said it had secured funding to see it through this year but warned profits would plunge after it trebled the impact of its losses on complex financial instruments.
