FTSE 100 - LOSERS
SABMiller, down 0.8%. The brewer said that growth in the third quarter continued to be driven by its emerging markets business. Although the group's organic revenue growth came in at 4% for the period, ahead of Shore Capital's 3% forecast, it fell below consensus expectations of 5%, according to a Bloomberg survey, says Shore Capital analyst Phil Carroll. Furthermore, Carroll is concerned that many of the company's key countries have seen their currencies weaken against the dollar. "Whilst the impact of this is seen on a short-term basis through FX translation in reported numbers, we wonder if there will be a latent impact on consumer spending if imported inflation comes through," Carroll says.

African Barrick Gold, up 7.7%. The gold production company said it has exceeded its initial full-year gold production guidance and continued its cost-reduction strategy. The company said its gold production of 641,931 ounces for 2013 was 3% higher than the previous year and significantly exceeded the company's full-year production guidance of between 540,000 and 600,000 ounces of gold. The company also said its preliminary fourth quarter all-in sustaining cost is USD1,171 per ounce of gold sold, down 30% on the previous year and 8% on the previous quarter.
Polymetal International, up 2.5%. The gold, silver and copper-mining exploration company said it has produced 1.3 million ounces of gold equivalent in 2013, a 21% increase on the previous year and above its production guidance of 1.2 million ounces.

FTSE 250 - LOSERS
PZ Cussons, down 2.6%. The company has revealed that revenue for the half-year was up 4.1% on the comparable period, in line with management expectations, as it boosted its interim dividend to 2.53 pence per share. However, Shore Capital analyst Darren Shirley believes that, looking ahead, currency headwinds in Australia and Indonesia are strengthening, and he expects this will hold back progress in Asia. Furthermore, Shirley believes that the Nigerian naira will create a mid-high single digit hit to the company's second-half performance in Africa.
