The Topix Index rose 0.5% to 3,162.84 as of 9:19 a.m. Tokyo time. Sony Group Corp. contributed the most to the increase, adding 1.2% Out of 1,675 stocks in the index, 963 rose and 619 fell, while 93 were unchanged.
The Nikkei 225 Stock Average advanced 0.7% to 44,678.12. Gains in technology stocks in the US point to buying of AI-related shares in Japan. The expiration of options and futures contracts on the Nikkei 225 Stock Average on Friday in the so-called special quotation settlement is also a factor for the market.
“With moderate growth seen in US CPI and the breach of the previous upper bound in US jobless claims, expectations for a rate cut at next week’s FOMC are even stronger,” said Nobuhiko Kuramochi, vice president of investment adviser Parasol Co. In Japan, AI-related shares are likely to continue rising, following strength in US technology stocks, he added.
