The 225-issue Nikkei average rallied to its highest level in more than a year Thursday, as investors bought back recently beaten down semiconductor-related shares on optimism for improved corporate earnings.
The Nikkei benchmark share average ended up 0.55 percent at 22,750.60. It earlier rose to 22,780.99, the highest since Oct. 18, 2018. So far it is up 13 percent for the year.
“We’re in the age of big data and artificial intelligence, and both require semiconductors,” said Kiyoshi Ishigane, chief fund manager at Mitsubishi UFJ Kokusai Asset Management Co. in Tokyo.
“I don’t see how you can argue that future demand for semiconductors will weaken. Japanese stocks can gain another 10 percent to 20 percent from current levels.”
Shares rose for the fourth consecutive trading session as investors who recently sold off Japanese technology stocks turned into bargain hunters after Microsoft Corp.’s higher-than-expected sales forecasts for its cloud computing services.
A slightly weaker yen, which tends to boost earnings repatriated from overseas, also supported share prices among Japan’s major exporters.
There were 166 advancers on the Nikkei index against 51 decliners on Thursday.
The information and technology sector was the biggest gainer, rising 0.25 percent. Chipmaking equipment manufacturer Tokyo Electron Ltd. rose 2.18 percent, while electronic devices maker Kyocera Corp. gained 1.13 percent.
The largest percentage gainers in the index were pharmaceutical company Eisai Co., up 15.3 percent, followed by parcel delivery firm Yamato Holdings Co., gaining 4.06 percent, and Hino Motors, up by 3.75 percent.
Eisai’s shares have gained rapidly since it agreed with its U.S. partner Biogen Inc. on Tuesday to revive plans to seek U.S. approval for an Alzheimer’s treatment.
The largest percentage losses in the index were materials maker Toray Industries Inc. down 4.35 percent, followed by SoftBank Group Corp. losing 2.94 percent, and property developer Tokyu Fudosan Holdings Corp. down by 2.59 percent.
SoftBank’s shares hit their lowest since Jan. 30 on Thursday on continued worries that its finances will weaken due to its bailout of office-space sharing startup WeWork.
The broader Topix index rose 0.34 percent to 1,643.74.
The volume of shares traded on the Tokyo Stock Exchange’s main board was 1.2 billion, compared with the average of 1.24 billion in the past 30 days.
