SINGAPORE/TOKYO (Reuters) – Asian shares took their cue from Wall Street and slipped on Friday, and Japanese stocks slumped after briefly jumping on the central bank’s statement that it would expand parts of its stimulus program. MSCI’s broadest index of Asia-Pacific shares outside Japan was down 0.3 percent. Japan’s Nikkei (.N225) rose briefly but fell back to end the day 1.9 percent lower.
