That policy outlook is continuing to provide a supportive backdrop to equities despite recent volatility,” ANZ Bank analysts wrote in a note. Japan’s benchmark Nikkei average edged up 0.22% into positive territory while China’s blue-chip CSI 300 index climed 0.51%. MSCI’s broadest index of Asia-Pacific shares outside Japan rose 0.31% to 554.56. Hong Kong’s Hang Seng index however was down 0.24%, wiping out morning gains.
