"Sony Corp soared 11 percent after Daiwa Securities
raised its rating to 'buy' from 'neutral,' saying that the
company could turn profitable in fiscal 2014 due to strong
smartphone sales. The stock closed at a 11-month high of 1,668
yen and was the main board's most traded stock by turnover.
Japan's business daily Nikkei reported that the Xperia Z, a
new smartphone model Sony launched last month, was the
top-selling model in Japan for four straight weeks."
