Asian shares hit a six-week high and the euro stayed under pressure on Wednesday as investors counted on the European Central Bank to unveil a stimulus drive, while the yen jumped after the Bank of Japan left policy unchanged. MSCI’s broadest index of Asia-Pacific shares outside Japan rose 1.3 percent, with shares in India (.BSESN) and New Zealand hitting record highs. Japan’s Nikkei (.N225) bucked the trend by slipping 0.5 percent and the yen gained 0.9 percent to 117.76 to the dollar (JPY=) after the BOJ did not expand its stimulus.
