LONDON (MarketWatch) -- Most U.K. stocks closed in the red Thursday after weaker-than-expected Chinese factory data created concerns about global growth, with banks and resource firms posting some of the biggest losses.

The FTSE 100 index dropped 0.8% to end at 6,773.28, the lowest closing level in more than a week.

Shares of Pearson sank 8.2% after the publisher of the Financial Times said it continues to face challenging trading conditions this year.

Resource firms were also lower, after a "flash" version of the HSBC/Markit China manufacturing purchasing managers index fell to a six-month low of 49.6, missing analyst expectations. A reading below 50 signals contraction. The resource sector is sensitive to growth indications from China as the country is a major user of natural resources. Metals prices were mixed.

Among miners, shares of Glencore Xstrata PLC (GLCNF) and Rio Tinto PLC (RIO) both lost 0.9%, while BHP Billiton PLC (BHP) fell 0.5%.

In the energy sector, BG Group PLC gave up 1.3% and BP PLC (BP) shed 1.1%.

Banks also dropped. Shares of HSBC Holdings PLC (HSBC) fell1.5% and Royal Bank of Scotland Group PLC (RBS) eased 0.9%.

EasyJet PLC lost 4.1% after the budget airliner said it expects to report a first-half pretax loss of between 70 million pounds ($116 million) and GBP90 million.

Also on decline, shares of SABMiller PLC dropped 2% after the brewer said it plans to invest $110 million expanding production capacity in Nigeria.

On a more upbeat note in London, shares of Marks and Spencer Group PLC climbed 2.6% after Exane BNP Paribas raised the retailer to outperform from underperform. The analysts said the company had endured three difficult years and profit declines, but that it's about to change as it revamps its approach to e-commerce.

SSE PLC climbed 0.2% after the utility firm lifted its dividend for the fiscal year 3% and reported a solid performance for the year so far.
