SK Hynix falls 15% on Nasdaq debut as AI chip rally cools
SK Hynix's American depositary receipts plunged 15% on their Nasdaq debut, dragging South Korea's benchmark index into a circuit-breaker halt as investors reassess inflated valuations in the artificial intelligence semiconductor sector.
SK Hynix’s American depositary receipts opened at $170 on their Nasdaq debut but quickly plummeted 15%, pushing the stock to a one-month low. The ADRs had priced at $149 each, representing a 2.7% premium to the underlying shares' three-session average trading price in Seoul.
The sudden selloff triggered a near 9% crash in South Korea's Kospi index, activating a temporary circuit breaker designed to halt panic selling. This dramatic market dislocation reflects growing caution across global semiconductor stocks just as the US second-quarter earnings season begins.
Despite the turbulent trading, the listing ranks as the second-largest equity offering in US history, trailing only SpaceX's record initial public offering last month. The transaction was more than seven times oversubscribed, pointing to robust institutional demand ahead of the launch.
SK Hynix did not pursue a traditional US IPO but instead listed ADRs, which are US-traded certificates representing shares already listed in South Korea. The company intends to use the capital raised to fund new manufacturing facilities.
The offering provides the chipmaker with direct access to the deepest pool of equity investors in the world. This strategic move comes as SK Hynix cements its position as a primary beneficiary of the artificial intelligence hardware boom.
The company's leadership in high-bandwidth memory chips has made it a critical supplier to the AI accelerator market. Investor enthusiasm for this dominance propelled an 807% surge in the stock over the past two years, making it a top-performing global semiconductor name.
However, the shares have now erased more than 30% of their value since hitting a record high in June. Market participants are increasingly skeptical about whether the rapid expansion in AI-related spending has pushed valuations beyond underlying fundamentals.
South Korea's equity market has functioned as a key barometer for the global AI trade this year, with semiconductor stocks driving the Kospi's outperformance. The current volatility suggests investors are waiting for proof that hyperscalers' massive AI investments will generate sustainable returns.
