The resource sector is off its lows, but weaker commodity prices and worse-than-expected updates from mining companies have encouraged traders to sell mineral extractors.
The world's largest mining company, BHP Billiton, reported a 30% decline in full-year profit earlier today. BHP is cautiously expanding its potash division, but the share price is 1.6% weaker.
The recently-merged miner Glencore Xstrata announced its first ever set of figures as a combined corporation, writing down £4.9 billion in assets. The stock is down by 2%.
John Wood Group posted an 18.6% rise in pre-tax profit for the first six months compared with the same period in 2012. The oil services provider lowered its annual forecast down to 10%-15% and as a result, the stock is off nearly 9%.
