LONDON/TOKYO—Shares from Asia to Europe gained on Wednesday on rising optimism about the global economy and corporate earnings, while government bond yields rose and the yen fell to its lowest in four years against the dollar.
The regional Euro STOXX 600 traded up 0.1 percent after opening in negative territory, amid a somewhat mixed picture for earnings even as investors were largely upbeat about prospects. German stocks also turned positive, adding 0.3 percent.
