The FTSE 100 was little changed on Tuesday, with declines across pharma, consumer and banking stocks offset by gains in commodity-related shares. AstraZeneca fell 1.3%, while GSK dropped 2.5%. BAT declined 0.7% and Rolls-Royce slipped 0.5%, while Lloyds Banking led losses among the banks, falling 1.2%. Computacenter closed 5% lower after initially rallying on strong results. In contrast, energy and mining stocks advanced as commodity prices strengthened. Shell gained 0.7% and BP rose 0.8%, while Rio Tinto added 1.5%, and Glencore surged 4% as copper prices extended their gains to another record high. Higher oil prices added to concerns that inflationary pressures could keep interest rates elevated, with Brent crude approaching $100 a barrel before paring some gains. Meanwhile, UK retail sales increased 0.7% in August, according to the British Retail Consortium, significantly below the 1.6% 12-month average and the 3.1% growth recorded in August last year.
