On September 10, SK hynix declined 3.06% in pre-market trading to $192.6/share, with turnover of $16.18 million, pulling back sharply after surging over 7% in the prior session to a record high above $196.

The retreat appears driven by a convergence of headwinds. Most notably, Kioxia CEO publicly warned that NAND flash prices have already risen enough, cautioning that further increases could damage long-term AI demand. The remarks injected uncertainty into the storage sector rally that Goldman Sachs had ignited just hours earlier. Meanwhile, large-scale bearish options activity weighed on sentiment, including an $8 million bear call spread and a $17.12 million dual-leg protective put structure targeting medium-term downside. SK hynix also reignited concerns by responding to reports that it may sell partial stakes in its Chongqing packaging facility, valued at approximately 4 trillion KRW. Broader US indices closed lower the prior session, with the Dow down 0.77% and Nasdaq off 0.64%, adding macro pressure.
