LONDON, Sept 24 (Reuters) - Britain's leading shares fell around midday on Friday, pulled lower by miners which were hit by comments from UBS and as investors remained nervous over the threat of a double-dip recession.
By 1046 GMT, the FTSE 100 <
> was down 17.92 points or 0.3 percent at 5,529.16, having closed 0.1 percent lower at 5,547.08 on Thursday, its third consecutive session of losses since hitting its highest close since late April on Monday.Global equities have been hit by downbeat data from the U.S. and Europe, which stoked fears over the strength of the global economic recovery.
"It's certainly been a choppy week for equity markets but the prospect of a double dip is looming yet again," Ben Critchley, sales trader at IG Index, said.
Miners <.FTNMX1770>, strong recent performers, were the biggest fallers on Friday, weighed on by a research note from UBS.
Anglo American <AAL.L>, Kazakhmys <KAZ.L>, Antofagasta <ANTO.L> and Vedanta <VED.L>, which were all downgraded by the broker, shed 1.2 to 3.2 percent.
UBS said in a note: "Unexpected government rulings on minerals leases and taxation in many national jurisdictions ... (are) challenging many sustainable corporate growth strategies."
The FTSE 100 bounced off its session low of 5,516.46, however, as German business sentiment rose unexpectedly in September, although companies now expect the pace of growth in Europe's largest economy to slow. [
]Wall Street futures pointed to a firmer open on Friday, with shares set to rebound ahead of a batch of U.S. data including August durable goods orders and new home sales.
"U.S. durable goods order readings ahead of the weekend break could easily inject another wave of pessimism should the number fall short of expectations," IG's Critchley said.
ORACLE SEES CHIPMAKER FIT
ARM Holdings <ARM.L> was the standout gainer among the blue chips, up 5.7 percent, as comments from the chief executive of U.S. software giant Oracle Corp <ORCL.O> revived bid speculation for the chip designer.
Oracle founder Larry Ellison, responding to a question from an analyst at an event, said he was more interested in acquiring companies with attractive technology than companies that provide services.
ARM shares have advanced by more than 130 percent in the current year, hitting an eight-year peak.
Hammerson <HMSO.L> rose 1.5 percent to be one of the top gainers on the FTSE 100 as Credit Suisse named the firm and British Land <BLND.L> as its top picks among real estate investment companies. The broker upgraded the sector to "benchmark" from "underweight".
Back among the fallers, banks <.FTNMX8350> were lower as risk appetite remained firmly off the table and after more sabre rattling from regulators.
Barclays <BARC.L> and Lloyds Banking Group <LLOY.L> were down 0.9 and 0.6 percent.
Britain's banks are facing a wide-ranging probe that will examine the break-up of retail and investment banks after the financial crisis forced taxpayers to pour billions of pounds into the sector. [
]HSBC <HSBA.L> shed 0.1 amid a dramatic upheaval among HSBC's top management after a boardroom row left the bank scrambling to limit damage to its reputation but unlikely to alter its increasing focus on Asia. [
