Blue-chip benchmark snaps weekly run of wins

LONDON (MarketWatch) -- U.K. stocks ended lower Friday a day after the FTSE 100 notched a fresh record.

The FTSE 100 shed 0.7% to 6,911.80, with mining stocks extending losses as prices for metals slid following better-than-expected figures in the U.S. jobs report for February (http://www.marketwatch.com/story/economy-gains-295000-jobs-in-february-2015-03-06). The data sparked a surge in the U.S. dollar (DXY) against major rivals, hurting dollar-denominated commodities such as copper, platinum and gold.

Trading at the bottom of the FTSE 100, Randgold Resources Ltd. fell 5.3%, and silver and gold miner Fresnillo PLC fell 5.2%. Iron-ore producer Anglo American PLC declined 2.5%.

Also, the pound (GBPUSD) fell to $1.5064, down from $1.5242 late Thursday, while the euro (EURUSD) dropped to a 12-year low. U.S. stocks were also hit (http://www.marketwatch.com/story/us-stocks-futures-waver-ahead-of-key-jobs-report-2015-03-06)(SPX) (DJI) on concern the jobs report will prompt the Federal Reserve to raise interest rates sooner than later.

Holding the top of the FTSE 100 were shares Weir Group PLC . They jumped 4.3%, the best gain in a month, following British media reports the energy-engineering group may be the target of a takeover offer.

For the week, the FTSE 100 finished 0.5% lower, breaking a streak of four weekly gains.

It was just on Thursday that the FTSE 100 logged its highest close ever (http://www.marketwatch.com/story/ftse-100-wobbles-as-aviva-rises-admiral-falls-boe-statement-on-tap-2015-03-05), climbing alongside European stocks as the European Central Bank said it will start its massive asset-purchase program on Monday.

Citigroup analysts said the QE program was "significant contributing factor" in its decision to raise targets on the Stoxx Europe 600 . For the FTSE 100, Citi held its end-of-2015 target at 7,700.

"It is harder to be as constructive on growth or re-rating, compared to the rest of Europe, and there is also near-term political risk given the forthcoming General Election," in the U.K. in May, said Citi analysts led by Jonathan Stubbs. Citi also unveiled a 2016 target of 8,700 for the FTSE 100.

Topping the FTSE 250 on Friday, Thomas Cook Group PLC shares surged 24.5% after China's Fosun International Ltd. agreed to buy a 5% stake in the travel services firm. (http://www.marketwatch.com/story/ftse-100-wobbles-as-aviva-rises-admiral-falls-boe-statement-on-tap-2015-03-05)
