Shares of Japan’s SoftBank Group resumed their slide on Friday, following a broader slump in AI-related stocks as investors once again grew wary of the sector’s lofty valuations.

The conglomerate, which holds a wide range of AI investments across infrastructure, semiconductor, and application companies, dropped over 8%.

This comes after the group’s shares gained nearly 3% in the previous session after plunging 10% on Wednesday and clocking their worst day since April.

Other Japanese tech stocks also declined. Semiconductor testing equipment maker Advantest fell over 6%, chipmaker Renesas Electronics fell nearly 4%, Tokyo Electron, a chip production equipment maker, fell 1.46%.
