SKHX Extends Its Slide as a Firmer Dollar Stacks on SK Hynix's Demand Scare

The Selloff That Won't Quit

SKHX is down 7.65% over the last 17 hours to about $1,664, and this isn't a fresh shock — it's the sixth day of the same trade. The selloff started on June 23, when Korean chip names cratered from a record high amid a global tech rout tied to reports that Nvidia may trim Rubin output and that SK Hynix is slowing its HBM4 capacity build. For a stock that had become the purest large-cap proxy for AI memory, any hint that demand is softening hits the multiple hard — SK Hynix fell roughly 12% in that single session.

Monday brought no relief. Even as Korea and SK Hynix unveiled fresh chip-investment plans at a presidential briefing, the shares slid more than 3% as the KOSPI sold off on a stronger dollar and broad profit-taking. After a run that took SK Hynix up roughly 280% on the year, this reads less like a verdict on the AI thesis and more like crowded positioning being unwound into known supply.

The FX Tax Hiding in the Oracle

Here's the part specific to SKHX and easy to miss: the perp doesn't track SK Hynix in won, it tracks the stock's KRW price converted to USD at the prevailing exchange rate. When the dollar firms against the won — exactly what reporting flagged into Monday's session — the USD-quoted SKHX price falls by more than the won-denominated move alone. You are effectively short the stock and short the currency at the same time.

That's why a roughly 3% move in Seoul can print as a steeper drop on the perp. It cuts both ways — a won bounce would amplify a recovery — but on the way down it means SKHX longs are paying an FX drag on top of the equity drawdown. Anyone trading this market off the underlying chart in won is reading only part of the move.

The $29 Billion Cap on Any Bounce

The reason no durable bid is forming sits two weeks out. SK Hynix is raising up to $29.4 billion in a Nasdaq ADR listing, an offering large enough to eclipse Alibaba's 2014 IPO and one that issues up to 17.79 million new shares. The timeline is now concrete: bookbuilding opens July 6, pricing follows, and trading begins around July 10, with ten ADRs representing each common share.

That's a dilution event landing on a stock still digesting a demand scare. Until the book is priced, the market knows fresh supply is coming and has every incentive to keep the underlying cheap — which is precisely how a 280% YTD winner ends up selling off into its own capital raise. The clearing event is the ADR price itself; until the July 9–10 print, dips here are buying directly into a known overhang.
