On July 28, SK hynix declined 3.1% overnight, trading at $138.59 per share, with turnover of approximately $55.77 million. The stock fell further below its July 9 IPO price of $149 per share.

The decline was triggered by a massive global memory chip sell-off. The listing of Chinese DRAM maker ChangXin Technology on the Shanghai Stock Exchange intensified market concerns over future DRAM supply competition. Simultaneously, the Korean KOSPI index plunged as much as 7.6%, with SK hynix Korean shares recording their largest-ever single-day drop of up to 30%. Samsung Electronics fell over 8%, and Japan's Kioxia dropped as much as 18%.

SK hynix completed a record $26.5 billion IPO earlier this month but has now broken below its offering price in less than one month of trading. Multiple analysts noted that the market concern centers not on short-term earnings but on potential structural shifts in global DRAM supply dynamics, though most institutions maintain that SK hynix, Micron, and Samsung retain a durable lead in AI-critical HBM technology.
