The FTSE 100 traded higher on Wednesday, building on a second consecutive record close above 9,000 points, lifted by optimism over progress in US trade talks. Sentiment improved after the US and Japan reached a trade agreement that imposes 15% tariffs, avoiding a previously planned 25% rate. The deal also includes a $550 billion fund for US investments. Informa led gains, jumping 3.5%, after upgrading its full-year underlying revenue growth forecast to over 6%, driven by 20% revenue growth and stronger-than-expected margins in the first half. The firm also announced 150 million GBP in additional share buybacks. Major stocks like AstraZeneca (2.5%), Shell (1%), BP (1%), GSK (1.6%), and Diageo (1.7%) also supported the index. On the downside, Fresnillo fell over 3.5% after reaffirming its silver production guidance but noting weaker contributions from Silverstream and lower ore grades at its namesake mine.
