The Nikkei Average rose ¥705 at the close on the 29th, ending trading at ¥64,659. The index rose in the morning on the back of gains in U.S. stocks, but Advantest's sharp move significantly affected the market, and prices were volatile at times during the day.
Advantest announced an upward revision, sending its share price up 6%. This lifted the Nikkei Average, while buying in AI-related stocks temporarily expanded before returning toward its highs in the afternoon.
Trading value on the TSE Prime Market was approximately ¥13.86 trillion, as trading expanded in response to demand related to TOPIX rebalancing. The TOPIX, which had declined at the midday break, secured a gain at the close.

Across the market, banking, securities and mining stocks advanced, while machinery, electrical equipment and textile stocks declined. Overall, movements in AI-related stocks and companies' earnings revisions influenced the Nikkei's performance.
