SK Hynix shares in Seoul fell more than 10% on Monday, wiping out much of the bullish momentum generated by the company's high-profile listing on the Nasdaq just days earlier.
The steep decline in the home market underscores the fragility of the recent rally, which was heavily fueled by retail investor enthusiasm and a surge in leveraged positions.
The sell-off came as traders began to liquidate positions following the US trading debut, exposing the stock to wild swings driven by speculative trading rather than fundamental shifts in the memory chip business.
The sharp reversal highlights the disconnect between the company's strategic expansion into US markets and the short-term trading dynamics dominating its primary listing in South Korea.
This volatility follows a period of intense interest in SK Hynix as a key beneficiary of the AI infrastructure build-out, with investors closely watching its competitive positioning against peers like Nvidia.
The recent Nasdaq listing was intended to broaden the shareholder base and increase liquidity, but the immediate aftermath has been marked by significant price instability.
