MSCI’s broadest index of Asia-Pacific shares outside Japan was up about 0.3 percent in late afternoon trade, after wobbling between positive and negative territory as it took its cues from a choppy, losing session on Wall Street overnight. Japan’s Nikkei stock average (.N225) ended down 0.7 percent, after the Bank of Japan offered a bleaker view on factory output. The BOJ maintained its massive asset buying program, as widely expected.
