FTSE 100 Index added 0.22% to trade at 5,508.30 at the time of writing. UK stocks found strong support after Ewald Nowotny, ECB policymaker, raised measures that may boost firepower of the bailout fund. However, a 0.7% contraction in UK's GDP in Q2 limited rally of riskier assets. Financial and technology stocks drugged the index higher, with Royal Bank of Scotland, Barclays and HSBC Holdings rising 3.03%, 2.19% and 2.03%, respectively. Meanwhile, mining and energy stocks were mixed amid global economic uncertainty. Rio Tinto and BHP Billiton advanced 0.74% and 1.13% while BP and Tullow Oil lost 0.11% and 4.53%.
