Shares of Kioxia Holdings <285A> rebounded sharply, temporarily rising nearly 5,000 yen to the 67,000 yen level to return to a record-high trajectory. After a pullback the previous day, renewed buying emerged today, underscoring strong investor appetite, particularly among overseas market participants.

In the U.S. market the previous day, major semiconductor memory maker Micron Technology surged up to 23%, drawing intense market attention. UBS lifted its price target for Micron roughly threefold, citing structural changes in the memory industry, a surprise move that drew massive inflows. The Micron rally spread to other semiconductor-related stocks, including Advanced Micro Devices and Applied Materials , which both posted significant gains. The Philadelphia Semiconductor Index (SOX) also gapped higher to reach a new record high.

SanDisk , which operates in the same sector and has a strategic partnership with Kioxia, also surged 7.8%. Driven by this momentum, large-scale funds, primarily from overseas, flowed into Kioxia. However, after touching the 67,000 yen level, concerns over the rapid short-term rally emerged, causing the stock to narrow its gains.
