SK Hynix IncADR premium at 35% is historically unsustainable and expected to narrow, weighing on ADR price.

SK Hynix's American depositary receipts are trading at a 35% premium over its South Korea-listed common stock, a gap that historical patterns suggest will narrow and weigh on the ADR price. The memory chip maker's first-quarter sales surged 198% year over year to $35.5 billion, while earnings jumped nearly 400% to almost $27 billion, driven by booming AI demand and a record 72% operating margin. Despite a price-to-earnings ratio of 28, well below the tech industry average of 35, the ADR premium has reached as high as 51%, far exceeding the typical 2% to 4% divergence found in a 2025 MCSI study. Analysts point to enormous U.S. flows into memory stocks at this exceptional moment, but caution that such a wide gap is unlikely to persist. Investors may want to wait until the premium cools significantly before considering the stock.
