LONDON, Nov 29 (Reuters) - Britain’s top share index fell on Tuesday, underperforming other European markets as energy and mining stocks were hit by weaker oil and metals prices.
The blue-chip FTSE 100 index, which is more heavily weighted towards commodity-related stocks than continental European indexes, was down 0.6 percent in morning trading.
Signs that leading oil exporters were struggling to agree a deal to cut production to reduce global oversupply ahead of a meeting on Wednesday pushed Brent crude down 1.6 percent, while copper, gold, iron ore and steel also fell.
That pushed the FTSE mining stocks index and the oil and gas index down 1.9 percent and 1.5 percent respectively.
“(With) continued production cut brinkmanship from both OPEC and Russia, scepticism is still rife about whether tomorrow’s official OPEC meeting in Vienna will be a success,” said Mike van Dulken, head of research at Accendo Markets.
Mining companies Fresnillo, Antofagasta and Randgold Resources were the biggest fallers, down by between 2.3 percent and 3 percent. Shares in BP dropped 1.6 percent while Royal Dutch Shell slipped 1.4 percent.
Aberdeen Asset Management fell 4.4 percent, after losing nearly 4 percent on Monday after its results, as RBC cut its target price on the stock. Other stocks with emerging markets exposure also came under pressure.
But banks stabilised after Monday’s fall, with Barclays rising 1.4 percent, even though Asia-exposed HSBC and Standard Chartered were flat.
Homebuilders Barratt Development, Persimmon and Taylor Wimpey also rose, gaining between 1.4 percent and 2.8 percent after Bank of England data showed mortgage approvals were stronger than expected in October.
Mid-cap stocks, which are less exposed to swings in commodity prices, rose. The FTSE 250 was up 0.1 percent.
Shares in broadband company TalkTalk rebounded 4.3 percent after touching a four-year low on Monday, as Britain’s telecoms regulator said it would try to force BT to legally separate its Openreach network infrastructure division into a legally separate entity.
This move would benefit smaller broadband firms such as TalkTalk as it would “allow them to see whether they have been paying over the odds for access to the UK’s copper and fibre optic network,” van Dulken said.
TalkTalk shares had fallen by a quarter over eight straight sessions after results earlier in the month, but have been up for the last three days. BT fell in early deals, but was last flat.
Mid-cap food service company SSP Group jumped 6.7 percent after reporting stronger revenues and profits.
