SK Hynix shares fell as investors grew cautious ahead of its third-quarter earnings report, expected later in October. Concerns included the potential effect of a stronger Korean won on overseas profits and the cost of large employee-bonus provisions.
The decline came amid a broader sell-off in memory-chip stocks. Investors reacted to Samsung Electronics’ record-breaking preliminary profits, which fell short of the highest analyst expectations, with a “sell-the-news” response. Negative sentiment persisted despite a positive report from Micron Technology pointing to tight supply and strong demand from the AI sector.
