On Thursday, the FTSE 100 experienced a 0.3% decline, primarily influenced by downturns in major entities such as HSBC, which fell by 1.5%, and AstraZeneca, which decreased by 0.5%. Convatec emerged as the day's most significant loser, plummeting 4.9% to its lowest point since January, following US investigations into imports of robotics, industrial machinery, and medical devices. Despite these setbacks, mining companies provided some market support amid high copper prices: Rio Tinto climbed 2%, Glencore saw a 0.6% rise, and Anglo American edged up by 0.3%. In contrast, Antofagasta dropped 2% after a notable 9% gain in the previous session. Meanwhile, Halma saw an increase of over 1% after it revised its full-year revenue forecast upward to "low double digit" growth from the previous "upper single digit," supported by strong performance in its Environmental and Analysis division, especially in photonics. The company also emphasized robust cash flow and a "healthy" acquisition strategy, having already finalized two acquisitions this year.
