According to Korea Exchange, SK Hynix's American Depositary Receipts (ADRs) listed on Nasdaq on July 10 have maintained a 14–50% premium relative to shares traded on the Korean exchange. As of July 15, ADRs traded at approximately 25% above domestic shares; on July 16, the premium widened to 42%. The persistent premium reflects constraints in converting between ADRs and domestic shares—ADR issuance is capped and reversal conversion is economically unfavorable for arbitrage traders.
Analysts expect the premium to normalize over time, establishing a new pricing mechanism between U.S. and Korean markets. A Hyundai Motor Securities researcher noted that TSMC's ADRs maintain a 25–30% premium without causing structural outflows in Taiwan, suggesting similar dynamics may stabilize SK Hynix's dual listing over the medium term.
