SKHX Extends Its Slide as SK hynix's Seoul Rout Overpowers a Rising Won

Why the Slide Keeps Going

SKHX at ~$1,331 is a continuation, not a new shock. The underlying — SK hynix's Seoul-listed common — is now roughly 25% off its June 30 peak of about 2.749 million won, the tail end of a chip rout that tumbled Samsung and SK hynix more than 9% in a single Seoul session at the start of July.

This is a sector rerating, not a company problem. The market is repricing the memory trade on the idea that the AI capex cycle is topping — the selloff accelerated on reports that Meta is building a cloud business to sell excess AI compute, read as a signal that hyperscaler demand for the high-bandwidth memory SK hynix dominates could soften, with oversupply worries layered on top. That's awkward for a name that had run over 260% year-to-date into late June and controls the majority of the HBM market feeding AI accelerators.

The FX Crosscurrent Nobody's Pricing

Here's the detail that makes this leg legible. SKHX is not the Seoul stock — it's an oracle-converted synthetic that takes the KRW share price and divides by the prevailing USD/KRW rate. So a *stronger* won mechanically *raises* the USD value of the perp, all else equal.

And the won did strengthen. On July 8, dollar-selling tied to SK hynix's own share offering showed up in the dollar-won forwards market and pushed the won to a more-than-one-month high — proceeds from a US raise get converted back to local currency, and that flow bids the won. That FX move should have been a tailwind for SKHX. Instead the perp is down 13% on the session. The takeaway: the Seoul equity leg is falling hard enough to eat a currency tailwind and keep sinking. Don't read the -13% as an FX artifact — the spot rout is doing the work.

Into a Record Debut

The timing is the wildcard. SK hynix is set to list ADRs on the Nasdaq on July 10 under the ticker SKHY, issuing 17.79 million new shares to raise roughly $29 billion gross (~$28 billion net) — poised to be the largest US listing ever by a foreign company, with likely inclusion in the Philadelphia Semiconductor Index behind it.

Demand and price action are pulling in opposite directions. Cornerstones Coatue, Baillie Gifford and Situational Awareness Partners indicated up to $7 billion combined and the book came together fast — yet SK hynix still had to cut its reference price from 2.555 million to 2.425 million won and trim the raise by about $1 billion as the stock fell into its own debut. The July 10 open becomes a fairly binary read on whether the AI buildout is still accelerating — extreme pre-listing swings that Bloomberg flagged as a wild card for the $28B deal are exactly what SKHX is tracking now.
