SK hynix (KRX:000660; NASDAQ:SKHY) closed Monday at 1.764 million won in Seoul, down 4.23%, as the broader KOSPI index dropped 4.46%. The decline in South Korea has amplified the pricing gap between the company's dual listings, with American depositary receipts (ADRs) on Nasdaq commanding a significant premium.
Each ADR represents one-tenth of a common share. Based on Monday's closing exchange rate of 1,481.5449 won per dollar, the Seoul-equivalent value per ADR stood at $119.06. However, Friday's Nasdaq close of $154.03 reflected a 29.4% premium. Premarket indications on Monday pushed the ADR price to $162.36, widening the premium to 36.4%, though these early estimates are subject to change before regular U.S. trading begins.
The spread between the two markets has expanded by nearly four percentage points from 25.6% on July 13, indicating sustained robust demand from U.S. investors seeking direct access to SK hynix shares. "ADRs tend to be priced at a premium as they provide U.S. investors with direct access to the stock for the first time," said analyst Nic Puckrin. He noted that arbitrage trades typically drive convergence over time.
Local shares have fallen 19.1% since July 10, accelerating from a 15.5% decline in the prior week. The stock now trades 40.9% below its intraday peak reached on June 25. The divergence highlights uneven price discovery, driven in part by domestic leverage dynamics. The value of assets held in Korean and foreign leveraged funds dropped from $53 billion on June 22 to $28 billion by Thursday, with onshore vehicles still accounting for two-thirds of the total.
Despite the share price weakness, SK hynix's business fundamentals remain strong. According to Counterpoint Research, the company captured 58% of high-bandwidth memory (HBM) revenue in the first quarter, far ahead of Samsung Electronics (KRX:005930) and Micron Technology (NASDAQ:MU), which each held 21% shares. However, analyst Ryu Young-ho cautioned that HBM4 shipments have yet to ramp up significantly, and SK hynix is less sensitive to traditional DRAM price increases due to its HBM-focused revenue mix.
Recent executive comments have introduced a valuation pause. SK Group Chairman Chey Tae-won stated, "Memory prices are currently at an abnormally high level," and emphasized the need to increase supply to curb rising chip prices. CEO Kwak Noh-jung added that customer demand continues to grow, but capacity remains constrained, and he anticipates the industry's most severe supply shortage will occur in 2027.
The near-term focus shifts to U.S. market activity this week. If Seoul stages a recovery, the premium could narrow even if ADR selling remains moderate. SK hynix is scheduled to report its next earnings on July 29 at 09:00 KST. Risks remain elevated: the premium could contract if ADRs decline, Seoul markets rebound, or the exchange rate shifts. Additional volatility may stem from slower HBM4 deliveries, reduced AI spending, or forced deleveraging.
The growing gap between the two markets now provides investors with more insight than each price individually. Upcoming results on July 29 will reveal whether earnings—rather than leverage—become the primary driver for SK hynix's valuation.
