Japanese corporations recorded their highest weekly equity purchases on record, significantly boosted by memory maker Kioxia Holdings Corp.'s share buyback program.

A significant decline in Kioxia Holdings Corp.'s shares is leading to speculation that the Japanese memory chipmaker will intensify efforts to boost returns for its shareholders.

China's Yangtze Memory Technologies Co. has reportedly surpassed Japan's Kioxia Holdings Corp. for the first time in flash memory shipments during the June quarter, benefiting from AI-driven shortages.

Kioxia Holdings Corp. is expected to experience more significant price swings as leveraged exchange-traded funds tracking the Japanese memory chipmaker's shares are set to be listed in the US.

Kioxia Holdings Corp. announced a 3-for-1 stock split after its profits fell short of expectations, suggesting a potential slowdown in the AI-driven surge in flash memory prices.
