SKHX Trails as SK Hynix Erases a 10% Circuit-Breaker Crash on the NVIDIA Pact

The Cash Market Took the Lead

The number on the screen is SKHX up 4.54% over 23 hours to $1,271, but that undersells what happened in Seoul. SK Hynix common opened Monday in free fall, down roughly 10%, as a Level 1 KOSPI circuit breaker tripped on an index plunge of more than 8%. By mid-session almost all of it was gone: the stock narrowed its loss to just 1.59% at 2,037,000 won once the NVIDIA partnership hit the tape, recovering from a Friday close near 2.07 million won that was itself down nearly 10%.

That recovery is what matters for the perp. SKHX is a synthetic that marks one SK Hynix share's KRW price converted to USD at spot, and with the won hovering near multi-year lows around 1,550 per dollar, 2,037,000 won maps to roughly $1,310. The perp at $1,271 is therefore trading a few percent *below* the recovered cash mark.

Run the weekend tape forward and you see the whole arc. SKHX spent the weekend at a deep discount, pricing the crash before it happened; by the early-Monday print it had closed that gap and briefly overshot to about $1,307. Then the stock caught up and passed it. The basis that paid all weekend — long the cheap perp against the rich stock — has inverted. The perp is the discounted leg again, this time because the equity out-recovered it, not because anyone is bracing for another leg down.

What NVIDIA Actually Signed

The catalyst is a multi-year technology partnership between NVIDIA and SK hynix, and it is not a vague memorandum. SK hynix committed to co-developing memory across NVIDIA's next-generation stack: the Vera Rubin AI supercomputer, Vera CPU, RTX Spark PCs and the Jetson Thor robotics platform. The same agreement has SK hynix using NVIDIA's CUDA-X libraries to accelerate chip design and Omniverse digital twins to push toward autonomous fab operations. Jensen Huang's framing was blunt: SK hynix "will continue to be NVIDIA's largest partner."

It also landed inside a broader sweep. NVIDIA used the same window to announce deals across Korea with SK Group, Naver and Doosan for AI data-center buildout. For a memory maker whose entire bull case is high-bandwidth memory allocation to the AI complex, a public, multi-year volume commitment from its single most important customer is exactly the kind of news that stops a 10% crash mid-fall.

Why the Dip Got Bought: $1 Trillion and a US Listing

A circuit-breaker crash got bought rather than sold because of the structural backdrop. SK hynix shares are up roughly 250% this year, and the company's market value topped $1 trillion last week — the third in Asia to do it after TSMC and Samsung. On top of that, SK hynix confidentially filed with the SEC in March for a US ADR listing, targeting the second half of 2026 and proceeds of up to $14 billion, and told investors in early June that the plan drew "tremendously positive" feedback.

For SKHX traders the takeaway is that the bid under SK Hynix is wide and structural, not a one-day reflex. But the same setup cuts both ways on the perp. Because SKHX converts a KRW price to dollars, a strong equity day can still print a muted USD candle when the won is weak — and right now it is. The cleanest read is convergence: with the stock at 2,037,000 won and the perp a few percent under the implied dollar mark near $1,310, SKHX is the discounted leg, and that gap closes if Seoul holds the recovery into the next session.
