SKHX Recovers 6.72% as the Circuit-Breaker Panic Fades and HBM4 Holds the Line

A Rebound, Not a New Bid

SKHX is up 6.72% over 23 hours to $1,334, and the honest read is that there's no fresh catalyst behind it. The move is the perp clawing back the ground it lost in Monday's KOSPI circuit-breaker selloff and settling roughly back at par with SK Hynix's 1,911,000 won cash close. Twenty-three hours ago the perp was pinned near its crash low as the index plunge dragged it down; everything since has been the dislocation normalizing, not new information hitting the tape. Treat this as mean reversion off a panic low, not a breakout.

What Took It Down Monday

The damage started in the US. Broadcom's soft AI-chip guidance — Q3 AI sales of $16 billion against a $17.2 billion estimate, with no raise to the full-year forecast — set off a $1.3 trillion semiconductor selloff that dragged Micron, AMD and Intel down double digits. That rolled into Asia: the KOSPI plunged more than 8% intraday Monday and tripped a Level 1 circuit breaker, with SK Hynix down as much as 10% before closing off 7.68% at 1,911,000 won — enough to knock it back out of the $1 trillion club it had only just joined. The perp tracked all of it.

The Floor Under the Name

What stopped the bleeding is structural, and it's why this bounced rather than bled out. On June 7, NVIDIA and SK hynix announced a multiyear memory partnership to co-develop memory for AI factories — HBM4 deliveries to NVIDIA starting in the second half of 2026 under a deal that runs through 2030, with Jensen Huang calling SK hynix NVIDIA's largest memory partner. SK hynix is projected to hold roughly 54% of the 2026 HBM4 market. Layer on a US listing targeted for June or July — an ADR offering of 2-3% of shares that could raise up to $14 billion to fund fabs in Korea and Indiana — and you have a name the market wants to buy the dips on. None of that is new today, which is exactly the point: the structural bid is what reasserts once the macro panic clears.

Where the Perp Sits Now

SKHX is a won-priced stock converted to USD at the prevailing FX rate, so two things move it: SK Hynix's Seoul tape and USD/KRW. Right now the perp is back near par with Monday's cash close, which means the discount that paid through the weekend and the crash has effectively closed — the easy dislocation trade is done. From here the perp is a clean proxy for the Tuesday Seoul session and the dollar-won: a firm cash open re-rates it higher, while renewed FX weakness can cut the USD price even if the won stock holds. With roughly $111 million in 24-hour volume on this market, the book is deep enough to express either side without much slippage.
