Japan's Nikkei drifts sideways as more earnings, US CPI awaited

Japan's Nikkei share average drifted sideways in a narrow range on Tuesday as investors braced for more local corporate earnings results and the release of all-important U.S. inflation figures the following day. The market was also cautious over a weakening currency and rising domestic bond yields amid speculation that the Bank of Japan could soon take additional policy tightening steps. The Nikkei entered the midday recess up 0.05% at 38,199.10, with 102 of its 225 components rising versus 123 that fell.
