Asian stocks were on the front foot on Friday, despite what has been a turbulent week politically in the region, with investors buoyed by good earnings reports and signs of more government support for China’s struggling economy. China’s bluechip stock index posted its biggest jump in more than five weeks, led by information technology companies, after US legislation to help its chip firms compete with Chinese rivals stoked expectations of more domestic support. Meanwhile, Japan’s Nikkei benchmark index surged above the 28,000 psychological barrier for the first time in nearly two months, helped by upbeat corporate earnings reports.
