UK equities extended their losses on Friday, with the FTSE 100 down 0.18% at close, amid continued weakness in mining stocks.
Antofagasta (ANTO.L) was the blue-chip index's biggest faller for a second consecutive session, down 4.69%, after the mining company cut its copper production guidance for full-year 2026 on Thursday.
"Following recent weather-related disruptions at Los Pelambres, management has lowered group copper production guidance by ~5% at the midpoint to 625-655 kt (from 650-700 kt), a risk we had previously highlighted following a seasonally soft start in H1'26. Los Pelambres has since resumed operations, with mining and processing rates ramping up as site conditions improve," Deutsche Bank Research said.
Meanwhile, Aviva (AV.L) gained 1.68% at close after reporting year-over-year growth in insurance revenue for the first half. However, the insurer's profit attributable to equity holders fell to 407 million pounds sterling from 698 million pounds a year earlier.
"Overall, we view 1H26 results as a small positive, with P&C ahead and Life in-line. GI COR was a 90bps beat at 93.3%, which was helped by higher PYD, with the company guiding to structurally higher releases going forward, although this has not led to better COR outlook. Company disclosed an 18% IRR in BPA, while Individual Protection and Health were slightly weak. While the shares have been strong into these results, on 10x FY27 P/E Aviva continues to trade at a meaningful discount to peers," according to RBC Capital Markets.
