London's FTSE 100 closed in the red for the fourth consecutive session on Thursday, falling 0.69%, as losses in mining and energy stocks outweighed stronger-than-expected UK economic data.
The UK's economy grew 0.4% in the second quarter, in line with expectations, following 0.6% growth in the previous quarter, preliminary data from the Office for National Statistics showed. GDP also rose 0.3% in June from May, beating expectations for no growth.
Berenberg said the data showed the UK economy had held up better than expected despite higher energy prices and mortgage rates. "We still expect quarter-over-quarter growth to slow in H2 as changing seasonal patterns exert their drags and the weakness of the labour market weighs on household incomes. However, the gain in GDP in June and the possibility of a sustained tailwind from AI infrastructure investment skews the risks towards a better outcome," the research firm added, maintaining its view that the Bank of England could resume cutting interest rates by the end of 2026.

"We had expected a guidance downgrade at the Q3 results, as company on course for [650,000 tonnes], but essentially the impact of the storms taking c.10-15kt of production out. Antofagasta appears to have been the most heavily impacted of the miners so far, with Lundin maintaining guidance," RBC Capital Markets said, while BofA Global Research trimmed the stock's price target to 46 pounds sterling from 47 pounds.
