The FTSE 100 index experienced a modest increase of 0.2% on Tuesday, recovering from a 0.3% decline noted in the previous trading session. The uptick was primarily driven by gains in the metal mining sector, where Anglo American saw a 3% rise, Antofagasta climbed by 1.8%, and both Glencore and Rio Tinto advanced by 1% each. The banking sector also contributed positively, with Barclays and Standard Chartered shares appreciating by 0.9%, HSBC Holdings increasing by 0.7%, and Lloyds Banking Group up by 0.6%. Additionally, AstraZeneca’s shares rose by 0.6% as investor sentiment improved following favorable developments in the industry. In the pharmaceuticals sector, Novo Nordisk's stock surged after receiving approval from the US to market an oral form of its popular obesity drug, Wegovy, boosting overall confidence in the industry. Conversely, major oil firms, including Shell and BP, experienced declines due to weak oil prices.
