SKHX Recovers 4% as SK Group's Chey Calls Memory Prices 'Abnormally High'

The Jeju Forum Signal

On July 20, at the Korea Chamber of Commerce Jeju Forum, SK Group Chairman Chey Tae-won called current memory prices "abnormally high" and said the industry should prioritize expanding supply over maximizing profit from the shortage. On its face that reads bearish coming from a memory maker. It isn't. He paired it with demand math only a supply-constrained bull would volunteer: overall memory demand up 50–60% next year, and AI-specific demand up 60–100%. The subtext is competitive, not cautious — talk prices down to keep PC, phone, and console makers buying, and to deny new entrants a fat-margin reason to build capacity. He also confirmed SK Hynix is weighing new fabs in the US and Korea, prioritizing speed of construction over labor cost. For a perp that tracks one Seoul-listed common share, that was the freshest tape-moving headline in the window, and it helped SKHX reclaim the ~$1,201 low it printed a session earlier.

The Premium Trade Still Runs the Tape

SKHX doesn't track the Nasdaq ADR — it tracks the Korean common share, which is the cheap leg of the most-watched arbitrage in Asian tech right now. After SK Hynix's record $26.5 billion ADR debut on July 10, the ADR premium to Seoul shares blew out past 50% because conversion was one-way: you could turn Korean shares into ADRs, but not back. That gap has since compressed to roughly 22%, down from about 38% two sessions earlier, as the market front-runs the July 29 open of two-way conversion. Don't assume it goes to zero. Bloomberg reports the premium may persist even after conversion opens, because retail conversion limits and FX-reporting friction blunt the arbitrage — TSMC's ADR has held a ~17–19% premium for years under nearly identical mechanics. But every basis point of convergence that does happen plays out on SKHX's side of the trade.

July 29 Is the Whole Game

The pivot is a single morning. SK Hynix's Q2 earnings call is confirmed for July 29, the same day the newly issued ADR-linked shares list in Seoul and two-way conversion opens. The bar is high: Korea Investment & Securities models Q2 operating profit near 60.4 trillion won — a 556% year-on-year jump, but roughly 8% under the ~65 trillion won consensus, after the firm cut its Q2 blended DRAM ASP growth estimate from 50% to 28.9% quarter-on-quarter. SK Hynix still holds the number-one HBM position at 56.4% share and ranks second in DRAM overall. So the month-end setup is a beat-or-miss earnings print landing at the exact moment the structural premium gap gets its first real arbitrage tool. That's the event SKHX is pricing toward — the 4% bounce is positioning, not resolution.
