SK Hynix (SKHY) had a wild Tuesday. Its U.S.-listed ADRs climbed 6.2% to $161.83 in premarket trading, even as the stock swung dramatically in South Korea — dropping as much as 9% early in the session before recovering to close up 3.7% at 1.913 million won ($1,279.90).

SK hynix Inc., SKHY

That gap between the two markets tells an interesting story. Since 10 ADRs equal one South Korean share, the premarket ADR price implies a valuation of $1,618.30 per share — a 26% premium to what investors in Seoul were paying.

The volatility follows SK Hynix’s record-breaking Nasdaq debut last Friday. The company raised $26.5 billion through its ADR offering, the largest U.S. listing ever by a foreign company. Its ADRs jumped nearly 13% on day one.

That strong opening triggered profit-taking when South Korean trading resumed Monday, sending the stock down 15%. The selling spilled into Tuesday before buyers stepped in.

Korean retail investors had been piling into SK Hynix for much of the year, using aggressive tools like leveraged ETFs. That added fuel to both the rally and the selloff.

Why the ADR Premium Matters

The 26% premium is notable in practical terms. ADRs can trade above the underlying shares due to U.S. investor demand and the friction involved in converting between the two instruments.

For investors watching valuation, SK Hynix ADRs traded at a forward price-to-earnings ratio of 5.71x as of Monday’s close, according to FactSet. Micron Technology (MU), the closest U.S. comparable, traded at 6.55x. That gap has drawn attention from analysts who see the ADRs as a cheaper entry point into the memory chip trade.

Micron itself rose 4.1% in premarket Tuesday, though the broader sector felt the pressure — SanDisk (SNDK) fell 12.63% as investors reassessed valuations across memory chip names.

What Analysts Are Saying

Despite the swings, analysts are not changing their tune on SK Hynix.

Samsung Securities analyst Jongwook Lee said investors shouldn’t read Monday’s drop as a sign the memory cycle has peaked. He described current market volatility as “a constant” rather than a warning signal.

Daniel Yoo, global strategist at Yuanta Securities, acknowledged that the expanded share count from the ADR offering added selling pressure. But he expects SK Hynix to recover over the next six to 12 months as investors settle on a fair value post-listing.

SK Hynix’s ADRs don’t yet carry formal analyst ratings. Among rated U.S. memory stocks, Micron holds a Strong Buy consensus with analysts projecting 67% upside.

The broader South Korean market also bounced back Tuesday. The Kospi index erased a 5% early loss to close up roughly 0.6%, with Samsung Electronics (SSNLF) helping stabilize the tech sector.
