Kioxia Holdings’ shares rose as much as 5.94% on May 25. This advance propelled Japan’s Nikkei 225 Stock Average past the 65,000 level for the first time.
The memory chip giant has now maintained a four-day winning streak. Its stock price increased nearly 30% during the previous week alone.
Investors attribute the rally to the global AI and semiconductor boom. Kioxia maintains a strong competitive position in the NAND flash memory market. Analysts cite the company's attractive valuation compared to its peers as a primary driver for the upward momentum.
Broader market sentiment also benefited from hopes regarding a U.S.-Iran ceasefire. Kioxia's performance led a wider rally among semiconductor-related stocks.
