TOKYO :Asian stock markets bounced between gains and losses on Thursday, while the yen and U.S. bonds attempted to rebound, as global investors struggled to find their footing in a wild week for markets. Japan's Nikkei share average swung from early losses of as much as 2.5 per cent and gains of 0.8 per cent before trading 0.6 per cent lower as of 0445 GMT. That left the index down 2.8 per cent for the week, following Monday's 12.4 per cent plunge, despite the ensuing two-day rebound. Tech
