SK Hynix Seoul Shares Drop 12% After Nasdaq Debut
SK Hynix stock fell sharply in South Korea on Monday following the chipmaker's high-profile U.S. market listing.
SK Hynix shares plunged more than 12% on the Seoul stock exchange Monday, a steep single-session selloff that followed the South Korean memory chipmaker's blockbuster debut on the Nasdaq.

The sharp decline in Seoul reflects a pattern commonly seen when major companies list shares on a second exchange. Domestic investors who had accumulated positions ahead of the U.S. listing often move to lock in gains, creating downward pressure on the home-market stock even as overseas sentiment remains elevated.

Whether Monday's Seoul selloff represents a short-term correction or a longer-term re-rating of the stock remains to be seen. Market watchers will closely track how the two listings trade relative to each other in the sessions ahead, and whether institutional flows stabilize the home-market price. For now, the divergence between the Nasdaq debut enthusiasm and the Seoul reaction captures the complexity of managing a dual-listed global equity.
