The largest foreign share sale in US history now has a full derivatives toolkit, giving traders new ways to bet on AI's most critical memory chip supplier
Options on SK Hynix’s American Depositary Receipts started trading on US exchanges on July 14, just days after the South Korean memory chip giant pulled off the largest share sale by a foreign company in US history. The $26.5 billion ADR offering landed on Nasdaq, and now the ripple effects are reaching the derivatives market.
Cboe and MIAX are among the exchanges listing options on the ADRs, which trade under the ticker SKHY.
From Seoul to Nasdaq in record fashion #
SK Hynix ADRs initially began trading on July 10 under the temporary symbol SKHYV before transitioning to SKHY on July 13. The shares were priced at $149 at offering and opened at $170, a 14% pop on day one.
That $26.5 billion raise eclipses every prior share sale by a foreign entity on US exchanges.
SK Hynix is the company making the high-bandwidth memory chips that power the GPUs Nvidia ships to every hyperscaler on the planet.
Why options matter here #
The introduction of options trading on July 14, just one day after SKHY began regular trading, is unusually fast. It reflects both exchange-level enthusiasm and a recognition that traders want more than just the ability to buy and hold shares.
The numbers back that up. Daily options premium in the semiconductor sector has recently surpassed $1 billion, driven largely by retail traders hungry for exposure to AI-adjacent names.
The AI supply chain gets its own asset class #
High-bandwidth memory is one of the tightest bottlenecks in AI infrastructure. Every next-generation GPU from Nvidia requires more of it, and SK Hynix has been the primary supplier.
What this means for investors #
The immediate implication is straightforward: investors now have a full toolkit for expressing views on SK Hynix. Bullish on AI memory demand? Buy calls. Think the 14% first-day pop was overdone? Buy puts or sell call spreads. Want to own shares but reduce cost basis? Write covered calls against your position.
There’s also a competitive landscape consideration. SK Hynix listing in the US puts it in direct comparison with Samsung and Micron, both of which are already accessible to American investors. Portfolio managers who previously had to choose between a Korean-listed stock with currency risk and its US-listed competitors now have a cleaner apples-to-apples comparison.
The risk side deserves attention too. SK Hynix derives significant revenue from a concentrated customer base, with Nvidia being the most prominent buyer. Any disruption to that relationship, whether from geopolitical tensions, export controls, or Nvidia developing alternative suppliers, would hit the stock hard.
