London’s FTSE 100 extended its summer rally on Friday, breaching 9,200 points for the first time in intraday trading after closing at a record high the previous session. The blue-chip benchmark is up for a fourth consecutive day, defying weakness on Wall Street and concerns about U.S. inflation. Gains were led by aerospace and defence stocks, which rose about 2%, and by financials. Insurer Aviva climbed 2.5% to a 17-year peak after lifting its interim dividend and reporting a 22% increase in half-year operating profit. Admiral Group jumped 6.6% on a 67% surge in pretax earnings, helping push the wider life and non-life insurers’ indices higher. Energy names were mixed. Centrica advanced 3.7% after announcing a £1.5 billion deal with U.S.-based Energy Capital Partners to acquire National Grid’s Grain LNG terminal. Oil and gas producers such as Harbour Energy and Shell slipped alongside lower crude prices. Latest economic data showed U.K. second-quarter GDP slowing less than economists expected, offering support to the market even as investors reassess the outlook for Federal Reserve rate cuts following stronger-than-forecast U.S. producer-price figures.
