On October 20, SK hynix fell 3.01% Overnight, trading at $138.75 per share, with turnover of $21.63 million.

The move aligned with a broader overnight pullback in memory stocks. Recent market updates indicated that SK hynix and Western Digital both retreated more than 1% in overnight trading, while a separate market interpretation noted that the sector had turned weaker after an earlier rebound in semiconductors and memory names.

Background pressure also remained from a regulatory development disclosed earlier: South Korean regulators said a potential listing of SK hynix subsidiary Solidigm could breach dual-listing restrictions and may require domestic review. While that issue did not prevent the prior session rebound, it remained a medium-term variable for valuation and sentiment as the company heads toward its next earnings report on October 27.
